TURN A ROTARY ENCODER INTO LINEAR POSITION SENSOR

TURN A ROTARY ENCODER INTO LINEAR POSITION SENSOR

Measuring Wheels Turn Rotary Encoders into Linear Position Sensors

Measuring Wheels: A Great Solution for Equipment Positioning Tasks

POSITAL has introduced a series of measuring wheel accessories for its IXARC family of rotary encoders. When one of these wheels is mounted on the shaft of an encoder, the result is an accurate and reliable instrument for measuring linear motion and position.

With the new measuring wheels, POSITAL provides a very convenient way to make linear displacement measurements while taking advantage of the proven performance of our extensive line of rotary encoders.

A Linear Measurement Range of up to 500 Kilometers!

The new measuring wheels are available in circumferences of 200 mm and 500 mm. When fitted to multiturn IXARC absolute encoders, this would translate into a linear measurement range of up to 500 kilometers!

Three rim treatments are available to ensure good traction between the wheel and a variety of surfaces.:

  • Knurled Aluminum
  • Smooth Polyurethane
  • Textured (knobby) Polyurethane

What is a Measuring Wheel? Watch and Learn!

Combination of Measuring Wheels and Programmable Incremental Encoders

POSITAL also offers great benefits from the combination of measuring wheels with our programmable incremental encoders. With this arrangement, a user could define exactly how many pulses the instrument would produce for a defined unit of linear motion. IXARC programmable encoders can be easily calibrated at the job site using POSITAL’s convenient UBIFAST programming tool.

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.

Now with the Open Source One-Cable-Technology BiSS LINE

MULTITURN KIT ENCODERS WITH BISS LINE INTERFACE

kit_encoder_biss_line

Now with the Open Source One-Cable-Technology BiSS LINE

POSITAL’s new family of kit encoders provide the manufacturers of motors and other machinery with rugged, accurate and cost-efficient tools for building rotary position feedback into their products. The new kit encoders are based on POSITAL’s highly successful self-contained magnetic rotary encoders. Now however, the core components of these instruments are available as separate assemblies that can be readily integrated into other products.

  • Asynchronous RS485 Interface, 4-Wire Configuration
  • Open Standard: BiSS Line
  • Smart Multiturn – Wiegand Technology – No Battery, No Gear!
  • Compact Single PCB Design
  • Auto-Calibration – No Mechanical Adjustment
  • Insensitive to Dust and Moisture

Non-Proprietary Interfaces Reduce Costs, Increase Versatility

The electronic interface for these encoders is based on non-proprietary BiSS Line and BiSS-C communications standards . Unlike proprietary, vendor-specific interfaces, these open-source standards are be supported by many manufacturers of sensors and motion controllers, freeing users from a “locked-in” relationship with a single supplier. Standard 4-wire RS485 connections are supported, so that motor manufacturers who adopt POSITAL kit encoders can often make use of existing connectors and cables. IP core software is available for FPGAs widely used in motion controllers. This reduces the development effort required to make use of BiSS communications technologies.

The BiSS Line standards also support a single cable approach to motor connections, with power and control wires combined in a single cable. Point-to-point or multi-slave network configurations are supported, simplifying wiring layouts in complex machines.

High Performance with Low Maintenance

The POSITAL kit encoder components offer advantages for motor and rotating equipment control feedback. Compared to analog resolvers, they provide improved accuracy and multiturn measurement capabilities. Their output is digital, which avoids the need for A/D converters in the control system. Compared to optical disk encoders, POSITAL’s magnetic encoders are less costly, less vulnerable to contamination from oil or dust and more resistant to shock and vibration. Multiturn absolute position measuring capability is based on an electronic rotation counter powered by the company’s well-proven Wiegand-effect energy harvesting technology . This system is self-powered, so rotation counts are always accurate, even if rotations occur when there is no control system power available. With no need for backup batteries and no need for periodic backup battery checks and replacements, maintenance requirements are significantly reduced.

Efficient Installation

POSITAL magnetic kit encoders are easy to incorporate into normal manufacturing processes since they don’t require near-cleanroom assembly conditions. A built-in self-calibration capability can be used to compensate for small sensor-to-shaft alignment errors occurring during assembly. The electronic components, including Hall-effect sensors, a 32-bit microprocessor and the Wiegand-wire energy harvesting system, are packaged in a convenient 36 mm diameter, 24.2mm deep unit. For servomotors with magnetic brakes, a special magnetic shield can be installed to isolate the magnetic pickups from external magnetic fields.

The resolution of the new POSITAL kit encoders is 17 bit, with an accuracy of better than +0.1°. The operating temperature range is -40 to +105 °C.

New Organization promotes No-Charge, Open Source Interface Technology for Industrial Control Systems

POSITAL PARTICIPATES IN LAUNCH OF BISS ASSOCIATION

biss_association

New Organization promotes No-Charge, Open Source Interface Technology for Industrial Control Systems

POSITAL FRABA has announced that it is participating as a founding member of the BiSS Association e.V. , a new organization dedicated to encouraging the use of the BiSS family of open-source industrial communications protocols.

BiSS communications protocols were developed by the German company iC-Haus GmbH as an efficient and feature-rich digital interface for communications between industrial sensors, actuators and control devices. iC-Haus is also the source of ASIC chips that support the implementation of this interface in industrial devices such as sensors, actuators and controllers.

Features of the New BiSS Interface

The BiSS interface is hardware compatible with the well-established SSI (Serial Synchronous Interface) digital interface, but offers significant enhancements. BiSS supports continuous (real-time) communications between controllers and sensors. BiSS Safety offers functionality for critical systems where safety ratings up to SIL 3 are required. Applications of the BiSS interface include manufacturing robotics, motor feedback, servo drives & motion control, position encoders and CNC drives.

An important new development is BiSS Line – an implementation of BiSS protocols that can be deployed in a single cable configuration and features forward error correction (FEC). This makes BiSS Line an ideal interface for servomotors where the single cable feature offers a significant reduction in wiring system complexity.

BiSS is offered as an open source interface. There are no licensing fees for either manufacturers of BiSS-enabled devices or their customers. BiSS Association e.V. is autorized to grant free-of-charge BiSS licenses to device manufacturers and BiSS users. The agreement defines rights and duties to make use of associated patents and trademarks for BiSS held by iC-Haus.

New BiSS Association Organization

The new BiSS Association organization aims to expand the use of BiSS technology throughout the world. It will also provide a communications platform for technical standards and cooperative marketing initiatives. POSITAL FRABA’S Jörg Paulus has been appointed Vice Chairman of the association, joining Dr. Heiner Flocke of iC-Haus (Chairman) and Alexander Ehnert of Hengstler GmbH (Treasurer). Membership in the BiSS Association is open to all companies and institutions. Members can participate in the development and promotion of this exciting new interface. Access to BiSS technologies and licensing arrangements are open to members and non-members alike.
