Xentaur LPDT Loop Powered Dewpoint Transmitter Repair Service

Professional diagnostic and board-level repair service for this Xentaur LPDT Loop Powered Dewpoint Transmitter.

The Xentaur LPDT is a loop‑powered (2‑wire) dew point transmitter that uses an aluminum oxide or HTF sensor and features a miniature LCD display with push‑button programming. Common failure modes for this class of instruments include loss of loop current due to wiring corrosion, display backlight failure, sensor drift from contamination or aging, and internal power supply degradation in the 24 V loop. For troubleshooting, first verify that the 2‑wire loop is receiving proper voltage/current (≈12–15 mA) and check for any visible cable damage or loose connectors; next inspect the LCD backlight and button response, and finally review the instrument’s self‑diagnostic error codes via the display to identify sensor or internal fault conditions.
