LORD Sensing Differential Variable Reluctance Transducer (DVRT®) systems enable precise micro-position measurement for a wide variety of applications. From slow, slight movements over time to high frequency vibration, the DVRT system provides accurate, repeatable measurement. Each system consists of a sensor, cable and signal conditioning module calibrated as one unit to ensure accuracy.
The Demod-DIGITAL stores specific calibration values in an internal lookup table and provides a highly accurate displacement output on both digital serial and analog output channels.

NOTE: Designed for use with LORD Sensing DVRT sensors. With a Demod-DIGITAL purchase, current LORD Sensing customers may return sensors for calibration free of charge.
