Position sensor for dosing systems

Paul Boughton

The WAL200 potentiometric sensor from Contelec is available exclusively in the UK from Variohm EuroSensor.

The tried and tested conductive plastic technology potentiometer has been developed specifically as a solution for valve position feedback in industrial volumetric and gravimetric dosing applications.

The durable and compact sensor is just 22mm in diameter and 7mm thick, with a 6mm diameter keyed through hole and an anti-twist pin for simple installation in syringe type dispensers.

Ensuring high accuracy and repeatability of the dosing process, the sensor has a ±1% linearity, ±0.3° resolution and a 280° electrical angle, which can be extended to a maximum of 340°. With a generous shock and vibration resistance the IP50 protection class sensor is cost effective and well suited solution for precise dosing control.
