GUI Software Programs Vert-X Angle Sensors

Variohm Eurosensor has launched a software application for communication and programming of Contelec Vert-X series contactless and non-contact angle sensors. As the UK distributor for the Swiss-manufactured range, Variohm has developed software with the ability to reconfigure and customise the sensor curve and output characteristics over its 0 to 360 measurement range. Vert-X Commander software is a PC-based application supplied with a special cable that connects Singleturn Vert-X sensors via an Aardvark USB host adapter.

With on-assembly sensor configuration, the software has the potential to simplify stock control and reduce build and design timescales by removing the need to purchase several different types of angle sensor across different machines. A GUI displays programmable and fixed information from the sensor's digital interface.

Programmable parameters include a selection of six different sensor types with varying gradient, deadband and curve characteristics. For each sensor type, the user can typically set specific voltage output and specify left and right angles with an adjustable deadband (or gap) angle. The information is displayed in a graph showing sensor angle vs voltage with a trace scaling function that allows closer examination of the output curve.

When the desired characteristics have been set on screen, a program key simply downloads the data to the sensor, overwriting the previously programmed information. Fixed displayed parameters include the sensor angle, output voltage level and as a primary quality control measure, the sensor serial number and a counter that records the number of times the sensor has been reprogrammed.

The compact and durable Vert-X range is aimed at precision, 0 to 360, angle measurement spanning applications from analytical instruments to extremely heavy-duty applications such as agricultural machinery, motorsports and automated industrial equipment where long life, high reliability and robust construction is required - often in space-restricted areas. Vert-X series sensors use hall-effect magnetic measuring technology, offering high-precision angle measurement in two design versions.

Singleturn contactless Vert-X sensors are characterised with bearing support for the rotating magnet and fixed sensor, whereas Singleturn non-contact Vert-X sensors are supplied in a two-part sensor and magnet design for free mounting. Both types may be used in normal ambient environments through to long life and zero-maintenance use in the most arduous and adverse conditions of high humidity, dampness, oil, dust and vibration.
