LVDT-ASC
Industrial AC-LVDT Signal Conditioner
DIN-Rail Mounted Signal Conditioning Module for AC LVDT Sensors
The LVDT-ASC is a DIN-rail mounted industrial signal conditioner for AC-excited LVDT sensors. The module provides sine-wave excitation to the LVDT primary, conditions the differential secondary signal using synchronous phase-sensitive demodulation, and provides simultaneous voltage and current outputs for PLC, DAQ, control, and monitoring systems.
