Designed for precision angle measurement, Contelec’s Vert-X 48E series non-contacting magnetic encoder is aimed at applications in agriculture, mining or construction equipment, and other applications where extreme environmental conditions exist and accurate control is required for steering, guiding or positioning etc.

  Contelec has recently announcedVert-X 37MT Hall Effect encoder combines a 16-bit single-turn angle resolution with 16-bit multi-turn count (65536 turns) for unconstrained position feedback, which is now available from Variohm EuroSensor.

Represented in the UK by Variohm EuroSensor, load and force sensor manufacturer ZEMIC has announced its participation in an innovative new machine for use at airports that scans, weighs and confirms that passenger’s carry-on luggage meets the weight and size restrictions required by the airlines.

An electric bike pedal force sensor has been developed by ZEMIC in conjunction with the Netherlands firm SPARTA – a successful e-bike brand in Europe. The sensor is a crucial component in the bike’s drive and control system that detects the pedal force applied, and through software settings determines a proportional amount of assisted motor power at the wheel.

ZEMIC has developed an electric bike pedal force sensor in conjunction with the Netherlands firm SPARTA – the most successful e-bike brand in Europe. The sensor is a crucial component in the bike’s drive and control system that detects the pedal force applied, and through software settings determines a proportional amount of assisted motor power at the wheel. Rather than a speed sensor, this control gives the rider a more intuitive riding experience with increased efficiency and longer battery life. The e-bike has several settings including Cruise, Tour and Sport.

The recently launched LP series low profile encoders from BEI Sensors are designed for high reliability position and speed feedback in harsh and challenging environments. Available from BEI’s UK distributor, Variohm EuroSensor, the IP66 rated encoder utilises innovative sensing technology with a choice of incremental or absolute single-turn output that allows for accurate position and speed feedback for demanding applications in industrial manufacturing, processing industries, agriculture, oil & gas and building automation. The impressive environmental specification includes temperature extremes of – 40 to +100⁰C, and thanks to encapsulated electronics, shock is rated to 3000 m/s2 (5 ms 1/2 sine) with vibration to 200 m/s2 (55 to 2000 Hz).

As in all areas of elite sports, teams and competitors go to great lengths to ensure their equipment set-up is optimised for the best possible performance levels. This is certainly the case for Loic Bruni, the 2015 UCI Mountain Bike & Trials Downhill World Champion. Loic and his French team have been using Variohm EuroSensor VLP and ELPM linear potentiometers to measure suspension-fork and frame shock absorber travel for more than three years. Fine tuning the set-up is critical and can make match- winning milliseconds of difference to the ‘sag’ of the bike – how it sits with the rider in real race conditions - and at the top end of the sport, dynamic measurement is essential.

Novotechnik’s RSB-3600 and RMB-3600 single- and multi-turn Hall Effect rotary position sensors are available in a wide choice of configuration options for maximum application flexibility. Available from Variohm EuroSensor, the highly durable sensor range is housed in a tough 36.5 mm diameter all-metal housing with a choice of solid or hollow shafts and environmental protection from IP67 to IP69K. With an absolute 12-bit resolution and linearity of +/- 0.03%, output options include analogue current or voltage and incremental for the single-turn model, and analogue and high-speed SSI for the multi-turn. Aimed at demanding positioning tasks on industrial and agricultural machinery or mobile and marine equipment, the sensors are also available in dual-channel redundant versions.  

Now available from Variohm EuroSensor, Novotechnik’s recently announced TF1 linear position sensor utilises an inductive measuring principle that is impervious to strong magnetic fields and has dynamic and environmental characteristics that suits arduous high precision and high speed positioning tasks on automated machinery. With its touchless and wear-free non-contacting design the TF1 provides a measurement range up to 1000 mm with a resolution down to 1 micron. Its 10 kHz refresh rate allows high speed position measurement and feedback, and a choice of current/voltage output as well as SSI, IO-Link and CANopen provides maximum interfacing flexibility. An Ethernet interface is also planned for release in the near future

Novotechnik’s RFC-4800 touchless technology, angle sensor, available from Variohm EuroSensor, is now offered with a CANopen interface increasing its extreme environment application flexibility in automotive, agricultural and construction equipment.

Variohm EuroSensor’s new VTP11 rotary position sensor combines well-proven resistive element technology and convenient D-shaft mounting in a durable and low cost IP66 rated package that ensures reliable and long-life operation for high performance motorsports - especially for throttle positon sensing. Variohm’s conductive plastic track and multiple fingered wiper assembly has been designed to maintain full sensing contact even in the most arduous shock and vibration conditions. With a 97⁰ measuring range and 5 kΩ throttle range resistance value from a 5…24 VDC input, the VTP11 will suit a wide variety of motorsports and specialist vehicle applications. The mechanical range of the sensor is 112⁰ and its rated operational life is 5 million cycles. Temperature extremes from -25 to +125 ºC with short term peaks to 150 ºC for 15 mins are possible.

With new Ex-approved pressure switches, level sensors and pressure transmitters from the German sensor manufacturer ADZ NAGANO, Variohm EuroSensor has extended its range of intrinsically-safe sensing and switching components. The new sensors will suit a variety of applications across chemical, oil & gas, HVAC, food & beverage and general engineering where ATEX certified approval is a prerequisite.

In an application where reliability and consistent operation are extremely critical, a pioneering and new DNA collection technology developed by M-Vac Systems uses pressure switches from the ultra-sensitive pressure, vacuum and differential switch manufacturer DesignFlex - represented exclusively in the UK by Variohm EuroSensor.
