The DEWETRON Rugged Industrial Encoder (RIE) was developed to be mounted between engine and brake shaft. The very rugged encoder works based on transmission light principle which avoids attrition and malfunction.

The DEWE-RIE offers TTL signal output and can be connected directly to any DEWE-CA or DEWETRON torsional and rotational vibration analysis system.

The function is based on transmission light principle. An infrared beam is emitted and received at the sensor unit. The customized marker disk (with slits) is mounted in-between the sensors gate.The slits will interrupt the infrared beam, the receiver transforms the light to voltage.

The marker disk is manufactured according to your specifications.
There are two possible types available:

• 360 slits = 1° resolution (outer diameter 120 mm)

• 720 slits = 0.5° resolution (outer diameter 230 mm)

(Other diameters on request)
