TILTIX INCLINOMETERS

LINARIX Linear Sensors Group

Inclinometers, also called tilt sensors are designed to measure the angle of an object with respect to the force of gravity. These tilt or level meters determine pitch and/or roll angle and output these values via the appropriate electrical interface. Inclinometers are easy to integrate to an application, because there is no need for mechanical linkages other than just the installation itself – a real advantage for design engineers. Posital developed several inclinometer types to have a suitable solution for different applications for each industry. Accurate measurement of the degree of tilt or inclination from a horizontal position is very important for many motion control systems or to ensure safety. 

  • Well Protected up to IP69K
  • Rugged and Compact Design
  • Measurement Range ±80° (Dual Axis) or 360° (Single Axis)

Dynamic Inclinometers

These inclinometers are equipped with a 3D MEMS accelerometer and a 3D MEMS gyroscope. A smart algorithm combines the signal of accelerometer and gyroscope to eliminate the effect of accelerations (e.g. due to rapid motion of the equipment), vibrations and shocks. 

  • Compensation of External Accelerations
  • Clean Measurement During Dynamic Movements
  • Accuracy 0.3°
  • Interfaces: CANopen

Static Inclinometers

These inclinometers are equipped with a 2D MEMS accelerometer as sensor cell. This type of inclinometer achieves a high accuracy in a static system or when the machine is only in a slow motion. 

  • Accuracy 0.1° or 0.5°
  • Interfaces: CANopen, Analog Current, Analog Voltage, RS232, SSI, J1939, DeviceNet

Installation and Mounting Options

Dependent on the application and machine it may be necessary to mount the inclinometer horizontally to monitor the tilt angle of two axes or to install the sensor vertically to measure one axis.

dual_axes

dual axis sensor is used for horizontal mounting and is ideal for leveling applications. This version got two outputs, one for the X-Axis and one for the Y-Axis. Each of the axes show the tilt angle with respect to the field of gravity.

single_axis

single axis tilt measurement version with one axis output is intended for vertical mounting.

Applications

Inclinometer offer an easy and efficient way of monitoring spatial orientation without the need for mechanical linkages – a real advantage for design engineers.

Static inclinometers can significantly improve operating safety in mobile machines, platform monitoring or medical applications by continuously monitoring the tilt or inclination angles. Inclinometers are much easier and thus less expensive to install compared to Rotary Encoders, which makes them ideal for applications like solar trackers. 

The dynamic inclinometer outputs a clean measurement signal and can be used reliably on mobile equipment such as construction machinery, mining equipment, agricultural machinery, cranes, and anywhere else where sudden movements, shocks and vibrations are likely to be encountered.

CLOSED-LOOP MOTOR FEEDBACK WITH THE
ABSOLUTE ADVANTAGE

  • 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.

FRABA GROUP CELEBRATES 100TH BIRTHDAY WITH STRONG FINANCIAL PERFORMANCE AND MARKET GROWTH

FRABA GROUP CELEBRATES 100TH BIRTHDAY WITH STRONG FINANCIAL PERFORMANCE AND MARKET GROWTH

christian_leeser_ceo

The international FRABA Group, which is about to mark the 100th anniversary of its founding, has enjoyed a year of significant growth in sales and profitability. In fiscal 2017 (ending December 31) turnover increased by 21.5% over the previous year, with total sales revenues of € 31.5 million. Growth has been driven by strong performance of the Group’s two product-oriented business units: POSITAL (industrial position/motion sensors) and VITECTOR(safety/security systems for large motorized doors). FRABA now has 220 employees, located at offices in Europe, Asia and the USA.

“Our success has been the result of hard work and careful planning” comments Christian Leeser, majority shareholder and CEO of the FRABA Group. “Innovative products, such as our high-resolution IXARC magnetic rotary encoders and the motor feedback Kit Encoders have been well received by the market”. Leeser continues: “Our future success will be supported by our Aachen-based R&D center, which is making significant progress in the development of innovative signal processing algorithms for of our magnetic encoder products and improved performance from our Wiegand wire energy harvesting technologies.”
While the VITECTOR business experienced significant growth, especially in North America, the largest area of advance was in the production of compact Wiegand devices for energy harvesting. In 2017, production of these ‘mini-power plants’ (which convert rotary motion into electrical energy through a magnetic process) more than doubled. FRABA, which is the exclusive producer of Wigand wire, makes use of this technology in its self-powered rotation counters for multi-turn encoders. It also supplies Wiegand modules, packaged as surface-mountable devices, to manufacturers of gas and water meters. Here, the energy harvesting capability is used to eliminate the need for external power or batteries. There are now more than 500,000 Wiegand devices in use worldwide.

WIEGAND WIRE ENERGY HARVESTING COMPONENTS

WIEGAND WIRE ENERGY HARVESTING COMPONENTS

posital_wiegand_sensoren_590

POSITAL’s Wiegand assemblies offer a compact and efficient way of harvesting power for electronic circuits in electromechanical devices, eliminating the need for backup batteries.

The operating principle of POSITAL’s Wiegand modules is simple. A “Wiegand wire” is a short length of specially prepared Vicalloy (vanadium-iron-cobalt) wire. When exposed to a changing external magnetic field (e.g. a nearby permanent magnet mounted on a rotating shaft) the Wiegand wire will initially retain its original magnetic polarity, and then abruptly ‘flip’ its polarity when the change to the external magnetic field reaches a certain threshold. This sudden change in the magnetic state of the core induces a current pulse in a copper coil wound around the Vicalloy core. This current pulse is very short-lived, but the energy harvested from the mechanical movement of the magnet can be captured and used to activate a low-power electronic circuit. An important feature of the Wiegand effect is that the amount of electric power generated with each reversal of the magnetic polarization is constant and completely independent of the rate of change of the external magnetic field, even if this happens very slowly. POSITAL Wiegand modules have been used to reliably power rotation counters in tens of millions of devices, including multi-turn rotary encoders, gas and water meters.

  • Production Since 1974 – Started by John R. Wiegand
  • Proven In Encoders & Water Meters Since > 10 Years
  • Used In Access Cards For > 30 Years
  • Power Supply For Future IoT Applications
  • High Energy Output of ~170 nJ
 “The process for making Wiegand wire from raw Vicalloy wire was invented by John Wiegand in the 1970’s” comments Christian Fell, Chief of Technology Development for POSITAL-FRABA. “It involves a complex set of steps, including cold-working the wire through a combination of stretching and twisting, then heat-treating the product to lock in the desired characteristics.” POSITAL acquired the original wire-conditioning machinery and intellectual property from the Wiegand estate in 2013. Fell continues: “This acquisition has meant that we have reliable supply of Wiegand wire. It also gave us an opportunity to refine the manufacturing process for improved product quality. Thanks to our research, we can now produce wires that reliably generate 190 nanojoules of energy at 7 volts with each polarity flip”.
Wiegand assemblies are a core component in POSITAL’s IXARC multiturn absolute rotary encoders, providing a maintenance-free method for powering the counter that records the number of complete rotations that the device experiences. POSITAL also offers Wigand assemblies to other manufacturers. These consist of a 15mm length of Wiegand wire surrounded by a copper coil, all contained in an SMD-mountable plastic structure. Wiegand wire production is carried out at locations in the U.S. and Europe, ensuring a stable, reliable supply chain. These assemblies can be used wherever low-cost, zero-maintenance, battery-free energy harvesting systems are needed to energize electronic counters and other low-power electronic devices.
