Displacement Signal Conditioner
MicroStrain Linear Variable Differential Transducer (LVDT) systems enable precise micro-position measurement for a variety of applications. Each system includes a sensor, cable, and signal conditioning module calibrated as one unit to ensure accurate, repeatable measurement.
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 MicroStrain LVDT sensors. With a Demod-DIGITAL purchase, current customers may return sensors for calibration free of charge.
