Product Overview

DRL‑DPM‑BKF is dual‑channel LVDT/RVDT position monitor module. It receives displacement sensor signals from valves, actuators and turbine governors, converts them into standard 4‑20 mA or 0‑10 V process output for DCS / PLC acquisition. On‑board configurable alarm thresholds trigger relay output for over‑travel or sensor‑fault events. Widely used for power‑plant turbine‑valve position monitoring and industrial actuator condition‑monitoring applications.

Application Notes

‑ Correctly set LVDT excitation‑frequency and gain‑parameters. ‑ Use shielded cable for LVDT sensor wiring. ‑ Perform full‑range calibration after installation. ‑ Typical deployment: power‑plant position‑monitor‑module spare‑part stocking.
