Description

PRODIS-TDC displays measurement values of magnetostrictive position sensors,

programmable scaling is provided to display units like mm or inch. The request signal will be

sent to the sensor periodically. The time between the start pulse and the stop pulse will be

counted by a high-resolution time-digital-converter (TDC). When used with POSICHRON

sensors the calibration parameters of the sensor will be uploaded to the meter at power-on.

This avoids a calibration when the sensor has been changed. A tare function or

programming lock can be activated with two control terminals.

Sensor excitation is supplied from the meter. Optional comparator functions with 4 NPN

open-collector outputs are available, additional 2 of them have relay output.
