PRODIS® PD-TDC Digital Process Meter for Time-of-flight Sensors • • • • • • Description Specifications For POSICHRON® position sensors with pulse output Integrated sensor supply 6-digit LED display RS-232 interface Optional 4 comparator Output Easy programming 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 a POSICHRON sensor the calibration parameters of the sensor will be uploaded to the meter at power-on. This avoids the need for recalibration when the sensor has been changed. A tare function or programming lock can be activated by two control terminals. Sensor excitation is supplied by the meter. Optional comparator functions with 4 NPN opencollector Output are available, additional 2 of them have relay output.
