Universal Transducer Interface (UTI)

The Universal Transducer Interface (UTI) is a sensor-to-time signal converter, based on a self-calibrating period-modulated oscillator. Sensing elements can be directly connected to the UTI without the need for extra electronics. The output is digital and can communicate with any type of micro-controller. The UTI can operate in 16 different modes. To obtain accurate results in any of these modes, a reference element of the same kind as the sensor is required.

The UTI provides interfacing for all kind of resistive and capacitive sensors.

For convenient design-in, there is an evaluation board available. The UTI evaluation board and free down-loadable software ensure that custom applications will be up and running in no time.

Key Features

  • Accurate measurement of various sensors:
  • Capacitance values (2-300 pF, 14 bits)
  • PT100/1000 elements (14 bits 9 mK)
  • Resistive bridges (12 bits, resolution 700 nV)

Kits and Modules

We have developed a few modules that make designer’s lives easier and show off the great features of our sensors. Some of these boards are being used in measurement and production environments due to their ease of installation and the high quality of the outputs.

For the temperature sensors we offer the SMTAS04 and SMTAS08 boards. These boards can be connected to any PC using a USB cable – no extra power supply needed! These boards have high accuracy and great resolution (0.01C).

We have also developed a new UTI evaluation board; the UTI Evaluation Kit USB. This board is a real “plug and play” system. Very accurate capacitance and resistance values can be measured. Porting the very low output voltages of infrared sensors to other equipment is very challenging so we have designed an IIC interface module and USB module that make this very easy.

Key Features

  • Easy connect to pc/lt via USB
  • For 4 or 8 SMT172 sensors
  • From SMT172 to I2C
  • From SMT172 to SMT160
  • For UTI applications
  • Infrared modules with I2C (I2C to USB available)
  • Free software in the design notes

Improving flow data with faster flow measurement

Our world is moving faster and flow processes are not immune to this. Newer industrial communications protocols can deliver flow data from hundreds of flow meters in less than a second. This increased speed of data acquisition can improve your process, but the speed of your flow sensor can improve the data itself. In this post, we’ll take a look at two examples of how Alicat’s sensor speed can make your flow data better.

Fast flow totalization of transient flow events at oil and natural gas wells

When you need to know the total amount of a gas that has flowed, instead of just the live flow rate, the measurement speed of your flow meter becomes much more critical. If your gas or liquid is already flowing, a flow totalizer can start and stop a timed measurement to take a sample of the total amount flowed during that time period. However, when you need to know the entire amount that has flowed from start to finish, significant amounts of your data can be lost as your flow meter comes up to speed. One of the more striking examples of this came through a research application with the US Environmental Protection Agency (EPA).

Alicat was contacted by an EPA researcher who needed to quantify how much gas was being emitted by pneumatic controllers at oil and natural gas well pads. At these sites, the natural gas that is already present is typically used to drive these controllers, and when they actuate some of the natural gas escapes into the atmosphere. The challenge was that most of these controllers were intermittent pneumatic controllers whose actuation periods lasted just a few seconds. A previous study had used thermal mass flow meters to totalize these emissions. However, the 1-3 second response rate of these meters meant that a significant proportion of the flow data was lost as the thermal flow meter tried to catch up with the transient flow rate.

In order to preserve the greatest amount of flow data, the EPA turned to Alicat’s pressure-based laminar flow meters. These instruments measure flow rates 1000 times each second and have a pneumatic measurement response time of 5 ms. With these flow meters installed, the researcher was able to follow the precise curve of the pneumatic controller’s actuation, from its explosive opening to its sudden shutting. The response speed of the sensor itself recorded much more of the available data compared to the thermal flow meter, making these measurements more accurate and reliable. The Alicat flow meter’s sensor speed was able to improve the quality of the data that the researchers obtained. You can read the resulting paper published in Earth and Environmental Sciences.

Improving the temporal resolution of flow readings for environmental monitoring and beyond

Another example of the benefits of fast flow measurement comes from the realm of ambient air monitoring. The gas analyzers that measure the concentrations of greenhouse gases in the air we breathe must be periodically calibrated to ensure they are measuring these small concentrations accurately. To do this, air monitoring technicians use dynamic dilution calibrators to generate known concentrations of the gas that the analyzer is designed to measure. Because this process is dynamic, the mass flow controllers inside these dilution calibrators must also be calibrated on a regular basis.

As gas analyzers have become more sensitive, the dilution calibrators have added mass flow controllers with lower flow rates, typically 10-20 sccm at the lowest, in order to simulate smaller gas concentrations. In the past, a positive-displacement (PD) flow meter was commonly used to calibrate these mass flow controllers. This type of flow meter provides an averaged flow rate that is calculated by dividing the total amount flowed by the duration of the measurement, but the very low flow rates required hid some critical data. At a flow rate of 20 sccm, such a flow meter takes about 20 seconds to complete a single measurement (see this video). At 1 sccm (the lowest point in the required 20-point calibration), the measurement time is more than 6 minutes.

When a mass flow controller failed its calibration, there was no indication of what was happening to the flow rate during the long measurement, because the only recorded data came at the end of the measurement. Perhaps the flow controller was oscillating on a regular cycle, or perhaps it started out well and then got clogged. Sometimes, the fault was that the PD meter got stuck in the middle of its measurement, but there was no way to diagnose this scenario without continuously observing the meter.

Air monitoring technicians in these situations have turned to Alicat’s fast flow meters to make visible the data that was hidden from the other flow meter. Because an Alicat responds pneumatically to changes in flow rates within 5-10 ms, the technicians are able to diagnose the cause of a failed calibration. When data is captured in real time, recurring oscillations that come from an underperforming mass flow controller are easily distinguished from a clog in the flow path. Indeed, when an Alicat is connected to a positive-displacement flow meter, it can diagnose failures that result when the puck of the PD meter stutters in its cylinder or when the puck takes too long to accelerate to match the speed of the flow.

Making distilled spirits better with Persedo and Alicat instruments

Alicat instruments are used in a wide variety of applications. We’re found in vacuum coating applications, food processing and the creation of fiber optics cabling. Alicat instruments test components to verify they are space worthy, provide flow control precise enough for even paint deposition from automated painting machines and precise enough to control propulsion on spacecraft while having no unintended recoil or counter effect from the device. With multidirectional flow control, we can mimic filling a car tire to pressure under test situations or simulate breathing. Alicat devices are built for each customer and with each application in mind making Alicat devices well suited to many diverse industries.

But in distilling and the refining of alcoholic spirits?

Yes, Alicat instruments can even make your mixed drink better. A company called Persedo uses Alicat mass flow controllers in their process that improves the quality of distilled spirits using a combination of ultrasonic energy, vacuum and extractive food grade gases.

The quality of a whiskey, vodka, rum or tequila can be dramatically improved in a matter of minutes by removing components which cannot be removed by distillation alone and by changing others in situ. Persedo uses an Alicat mass flow controller to precisely control flow rates of food-grade gases flow into their distilled spirits processing system. By passing two gases through the Alicat instrument, they are able to selectively strip off-flavors and off-odors from distilled spirits. The system has been used to process as many as 1000 spirit test samples.

“No other device offered us the cost-effective, dynamic process control capability and precise control (better than 0.5% of total volume) of flow rates made possible by a mass flow controller from Alicat,” said Greg George, the senior chemist and technology lead. “Precise measurements of volume flow rate corrected for variations of temperature and input pressure from tank gases is key to the quality control in our process.”

ALICAT MCR Series High Flow Gas Mass Flow Controller

Alicat MCR Series High Flow Gas Mass Flow Controller

Because Alicat devices can be controlled simply from the home screen or through various communication and industrial protocols, it is easy for Persedo and other customers to tie Alicat devices into the rest of the instrumentation and have them communicating through, for example, RS-232 to a computer without any additional modifications. Clear communication means speed and accuracy are increased. It is easy to make adjustments as needed, from flow rates to turndown ratios and even to the percentages of gases flowing into the system.

Challenge us with a new application or process. Alicat instruments are being used to improve outcomes in new and exciting ways on a regular basis. With a team of skilled Applications Engineers working with each customer every step of the way and a cohort of test, electrical and fluid dynamic engineers developing the next generation of our devices, Alicat devices are always evolving and moving science and technology forward.

Flow and pressure control tailored for you

Highly customized flow and pressure control for demanding applications

You know your process. We know the parts you need to help get you there.

An Alicat PC-15PSIG-D pressure controller

At Alicat, we are not only focused on accuracy but customizability. We give our customers the best solution for their application, whether that be in a humid, corrosive or heavily regulated environment. Every Alicat pressure, liquid or mass flow controller is completely tailored to the customer’s needs, from flow rates to communication protocols.

Alicat devices are as diverse as the applications they are used in. For example, one customer needed to control pressure in a test environment to adjust humidity. They purchased this device: PC-15PSIG-D/5P, 5IN; a 15 PSIG pressure controller. For many customers, this level of customization is enough to satisfy the application needs.

However, some customers need more.

A customer called us looking for a pressure controller that could control gas at 155 PSIG and handle flow up to 5,000 SLPM. The controller needed to be placed in an OEM box system but not lose interactivity from outside of the box. Within the box, the system was set to operate at temperatures up to 70 oC, and to be consistent with the rest of the equipment the device required analog signals and connections.

They also expressed some concerns to us: the system included pressure sensitive instruments which would break above 155 PSIG. Since the supply pressure was 180 PSIG this would damage or break the instruments, so the controller needed to measure pressure precisely at these sensitive instruments to ensure the pressure limit was not exceeded. While the operating temperature was 70 oC, the storage temperature of the box dropped down to -50 oC making condensation a big concern. With previous Alicat devices they’ve purchased, they noticed that the devices retained the last setpoint in its memory at power up, which was a security concern.

The instrument we designed for this customer addresses all of these concerns and is represented by the part number below:

PCRH3-100PSIG-RD-REMOTE-M12-40×55-SAE24-CC/CP, 5IN, RANGE (155 PSIG), P1: 180 PSIG, FLOW (5000 SLPM), GT[1], PUSP: 0, RD: 1.5’, REM: 1’

Now, this might look a lot like alphabet soup, but every letter and number lets us know exactly what this Alicat will look like.

Alicat PCRH3-100PSIG-RD-REMOTE high flow pressure controller with remote sense port and panel-mounting

Let’s walk through the part number:

High-flow pressure control: PCRH…40×55…P1: 180 PSIG, FLOW (5000 SLPM)

The first letters, simply put, designate that the device is a pressure controller, shown as PC. The RH afterwards means that this device has a pair of Rolamite valves in Hammerhead configuration. This allows for 5,000 SLPM high flow capacity. Hammerhead valves open and close simultaneously which doubles the surface area of the valve orifices, allowing more flow. Additionally, we built the valves with a custom size of 40×55, 40 being the orifice size (0.040”) and 55 being the number of holes in the Rolamite hole pattern. This specific hole pattern was determined to afford the greatest control across the expected range of inlet pressures (P1: 180 PSIG) and desired maximum flow rate (FLOW: 5000 SLPM).

Remote pressure sensing: 3

The customer wanted to maintain pressure after a delicate system of other instruments, but needed to regulate the airflow before it reached this system. The 3 signifies a remote sense port, which allows such pressure controllers to sense flow in a different area than where the valves are controlling the flow. This system is ideal in applications with limited space because the valve does not need to be located where pressure is being measured.

Customized pressure range: 100 PSIG…RANGE (155 PSIG)

The maximum pressure that the customer intended to control was 155 PSIG, so we modified the sensor range from the 0-100 PSIG stock sensor range to 0-155 PSIG.

Designed for panel-mounting: RD-REMOTE…RD: 1.5’, REM: 1’

This pressure control system was located inside of a box, but needed to be controlled from the outside. A remote display, noted as RD, allows the display to be mounted outside of the box, giving user access to all of the functions inside. RD: 1.5’ is the length of the cable that connects the remote display to the rest of the controller. The remote display was tested to withstand temperatures down to -50 oC, the lowest anticipated storage temperature.

With operating temperatures within the boxed system as hot as 70 oC, a REMOTE electronics package was specified. In high temperature scenarios which would damage the standard electronics, we separate the sensor assembly from the rest of the electronics package, so only the sensor interacts with high temperatures and the electronics are kept safe. REM: 1’ is the custom length of the cabling needed to connect the electronics to the sensor and flow body of the device.

Locking industrial connector: M12

The customer requested a locking M12 electrical connector to keep their system from coming unplugged inside the box.

Coated to protect against condensation: CC

Moving from the -50 oC storage temperature to room temperature would sometimes lead to condensation within the system, and this could short out the electronics. To prevent this, we added a protective conformal coating (CC) on the circuit board to protect against any condensation.

SAE24 fittings

The customer was already using SAE24 threaded process connections, so we matched it.

Mismatched analog signals: CP, 5IN

Another customization for this device is a mismatched analog input and output: a 4-20 mA output pressure data (CP) and a 0-5 Vdc setpoint input signal (5IN). Typically customers use an input and output that match, but this customer needed a mismatched setup to make this pressure controller work with their existing system signals, including a PLC that has an output of 0-5Vdc.

Remote analog tare: GT[1]

Because the customer was not using a digital interface for communications with the PLC, they needed a way to remotely tare the controller using analog signals. To satisfy this need, we designed this device to be tared by grounding Pin 1 of the M12 connector.

Preconfigured setpoint: PUSP: 0

To avoid revealing potentially sensitive information, this pressure controller will always bring up a setpoint of 0 PSIG (PUSP: 0).

Tough environments call for tougher instruments

Alicat instruments are built specifically for the conditions under which they will operate and the environments where they will be used, according to each customer’s needs. We work directly with customers to understand the stressors that will be placed on the instrument to ensure that every Alicat is up to the challenges they may experience in the field, lab or factory. Because the best repair is the one you never need, Alicat has a number of options to keep your process flowing smoothly.

In a precision test setting, it is unlikely that errant particulates, changes in ambient conditions or back flow of water will ever reach instrumentation. But Alicat instruments are often used far from the clean room. They are used to calibrate air monitors where the weather is a factor. They are used to maintain pressure and control gas mixtures in bioreactors, where cleaning means running the risk of splashing instruments. Some processes require the use of gases far more aggressive than air and other such nonreactive gases.

Humidity

In ambient air monitoring applications, humidified air can make it difficult to achieve the required accuracy in the field, especially when it is hot and humid. That is why we developed the FP-25. This flow meter incorporates a live humidity sensor that ensures accuracy of measurement at any temperature and humidity.

Recently we worked with an air monitoring customer who needed to control the flow of ambient air in humid areas at a high level of accuracy. We developed a flow controller that uses the same internal relative humidity sensor and software to correct readings based on relative humidity that we use in the FP-25. This allows for accurate sampling of ambient air as temperature and humidity change.

Water

Water outside the process line can cause issues as well. While some solutions might include creating some sort of protective box around process control instrumentation, or simply placing a plastic bag over the equipment and hoping for the best, we can build units to be rated up to IP66. Because our gas flow bodies are the same as our liquid flow bodies, a little water in the system won’t cause complete failure of the device, provided that it can be dried out later. Additionally, we have a conformal coating option to protect the interior electronics for situations where changes in temperature can cause condensation. Rain, back splash from a hose or conditions that might lead to condensation on or within the instrument are non-issues for Alicat instruments equipped with these options.

And if water or other damaging conditions are anticipated to a point where the electronics are at risk of damage greater than what can be protected with an IP66 rating or coating, we can build the device with the sensor and the electronics package as a separate remote option. This option is most frequently used in high heat environments, but can efficiently remove the more sensitive electronics away from wet conditions.

Corrosive Gases

Some processes throw more at the device than the forces of Mother Nature, and not all gases are as gentle as air, nitrogen or other common gases. Many customer processes require corrosive gases like ammonia or sulfur dioxide that could cause damage to the instrument. Depending on the gas being used, we can use FFKM or EPDM elastomers and stainless steel components. For some applications, we can customize from there, too. Our S series instruments are built with 316L stainless steel sensors, and in many cases the flow bodies and valving can also be ordered as 316L.

Hazardous Environments

For processes and environments that are potentially explosive, most Alicat instruments can be built with a CSA Class 1 Division 2/ATEX Zone 2 area certification. These instruments can be used in oil and gas applications where exposure to combustible gases is possible.

Your process can be messy, rough, jarring and abrasive. The last thing you want to worry about is your process control instrumentation being too delicate to handle the task. That’s why at Alicat we custom-build each unit with the customer’s process in mind. These Alicats are not just built to withstand tough process conditions; they can be configured to thrive in harsh ambient conditions as well. Backed by annual recalibrations and our limited lifetime warranty, an Alicat instrument will keep your process running smoothly, even in challenging environments, for years to come.

Your process, your project and the end results are what are most important. Spend your time on the things that matter, not worrying about your instrumentation.

CLOSED-LOOP MOTOR FEEDBACK WITH THE ABSOLUTE ADVANTAGE

CLOSED-LOOP MOTOR FEEDBACK WITH THE
ABSOLUTE ADVANTAGE

stepper_kits_1

Upgrade Your Existing Motion Control Application

POSITAL has expanded its line of kit-style encoders for feedback for servo and stepper motors with new models that utilize the same mounting form factor as incremental kit encoders from US Digital, Broadcom and other manufacturers.

  • Mechanical Drop In Replacement for Easy Upgrade to Absolute Position Control
  • Same Footprints as US Digital’s E5 Models and Broadcom’s (Avago) HEDS-5500 Models
  • Identical Assembly Procedure – No Training Required
  • Various Hub Diameters from 4 mm to 10 mm (and 1/4 to 3/8 inch)
  • Magnetic Technology Which Is Generally More Robust Than Optical
  • Improved Connectivity via M12 Connector Additionally Available

See our Cross Reference Guide

POSITAL kit encoders provide absolute position feedback so that the control system always has complete information on the physical position of the mechanical components that it is directing. “Absolute position feedback is a natural way of providing accurate position control” comments Jim Stevens, market specialist for robotics at POSITAL. “Almost any position feedback application could be absolute-based. Many current systems were designed around incremental encoders because incremental feedback devices were historically much less expensive than their absolute counterparts.” However, with the introduction of POSITAL’s absolute kit encoders at prices much more in line with incremental devices, system designers no longer have to work around the shortcomings of incremental feedback in an absolute position world.
Incremental encoders are effective for speed control. However, to monitor absolute position, the controller needs to maintain a complete count of the number of pulses received from the encoder. This can lead to problems. If, for example, the pulse count becomes corrupted due to a power outage, or if the control system fails to update the pulse count when the machine moves, positional accuracy is lost. The usual remedy is to “re-home” the machine by returning it to a known reference position and zeroing the pulse counts. By contrast, absolute encoders measure position directly. After a power outage, the controller can re-establish complete knowledge of the position of mechanical components by simply polling the sensors and reading their rotational position.

Multiturn Absolute Kit Encoders Provide Robust Solution

Multiturn Absolute Kit Encoders from POSITAL are based on magnetic sensing technology which provides a very robust encoder solution. The multiturn counting system is powered by Wiegand wire energy harvesting technology, which enables the absolute encoder to maintain true absolute position over power cycles and rotation of the encoder during power off conditions.

With 17 bits (131072 positions) of single turn resolution and 16 bits (65536 turns) of multiturn range, KCD Absolute kit encoders from POSITAL are ideal for position control applications.

Meet an Alicat: In the lab with Foose

The Alicat Touch

When you call Alicat you will never hear a robotic voice directing you to press some combination of numbers. You will never be left to navigate a frustrating menu. You will never have to fend for yourself on the phone. When you call Alicat, or chat with us online, you’ll talk directly with one of our Applications Engineers. Our Apps Engineers, as we call them, each have unique backgrounds in scientific and technological fields. And, of course, they know the ins and outs of all our instruments.

Alicat is able to produce highly customized instruments with some of the shortest lead times in the industry in part because our Apps Engineers are multidisciplinary experts and are very familiar with our mass flow and pressure controllers. They are always ready to jump up and head to the production line, engineering or test lab to work out the best solution for each customer – fast.

With hundreds of variations of mass flow and pressure controllers and just as many interesting and varied uses needing just as many interesting solutions, some of our Apps Engineers spend their time working out solutions as much as they do talking with customers. This is to everyone’s benefit because it can lead to improvements to devices and new ways applications to use an Alicat.

One Apps Engineer, Foose, is often in the test lab, surrounded by tangles of wires, equipment and devices. For every minute he spends on the phone with customers, he spends one in the lab solving their problems.

Foose is a chemist with the heart of a tinkerer. Like most Alicats, he is solution driven. He not only identifies the source of the problem, but the cause to ensure that he can help customers purchase, troubleshoot or fix their device – not just the right way but the best way. He’s so good at fixing things that when one of us is having an issue with the new demo for an upcoming trade show, setting up the equipment for a presentation or fixing the electronics in an old arcade game, we all go to him.

I recently sat down with Foose to ask him a few questions:

What is your favorite part of the day?

Since we are based in Arizona and are ahead of the clock from many of our customers, the later part of the day is when I have time to expand my knowledge of our own products and ways they are used. Currently the bulk of this special projects time is spent learning to program PLCs and use automation software so that I can better troubleshoot our devices and understand how our products interact with industrial systems.

What is the most interesting project you have worked on?

My favorite application that I’ve worked on was a research project designing an olfactometer to test a dog’s ability to distinguish very low concentration odorants. I love animals, and the application was memorable and unique. The basic parameters of the system were already understood by the customer, but I was able to show how our very high turndown ratios could allow a handful of dilution steps to deliver accurate odorant concentrations across many orders of magnitude, how the customer could improve repeatability with active backpressure control and how we could customize the valve configuration to reduce system purge time between experiments.

How are you Alicat fast?

I’m good at troubleshooting. I always want to know more about how devices are built, how they are used, how they perform and how they break.  Sometimes this means I can save customers expensive downtime by helping them identify complex problems and fix equipment in the field without ever having to return a device to Alicat. I often spend time in the lab making short instructional documents for customers who need to modify or configure our devices in a certain way. For example, one time a customer broke the front display of their Alicat and wanted to return it for repair. I know that replacing the front display cover and membrane switch is a fairly simple task requiring only a few minutes and some simple hand tools but learning how to do it over the phone would be harder than following a written guide with pictures. I created a small guide on how to do this simple repair, overnighted the customer a membrane switch and the customer’s process was back up and running in less than 24 hours.

Alicats, from the Apps Engineer you talk to on the phone when you place your order, to the Calibrator in production, are all working to make every instrument we sell exactly what each customer needs, as fast as possible. All while…

  • Maintaining NIST-traceable: +/- (0.8% of the reading + 0.2% of the full-scale range) on mass flow controllers and NIST-traceable: +/- 0.25% of the full-scale range for pressure controllers.
  • Collecting data fast with response time of 50-100ms on readings.
  • Being easy to use, right out of the box – with straightforward plug and play set up, front display controls and clear data readings – so processes aren’t held up by installation.
