Proximitor monitor for 3500 machinery protection rack. It excites eddy current probe, processes clearance signal and converts it into standard voltage value. It compares measured value against configured alarm and trip setpoints, outputs relay status and analog signal to DCS or SCADA, with built-in cable break and short circuit detection.

Certification: ATEX, CE, TÜV

Signal conditioning board, oscillator circuit, threshold comparison logic, relay output group, status LED and backplane connector. Common faults: zero drift, probe excitation failure, false alarm, backplane communication failure.
