Proximitor monitor supplies excitation signal to eddy current probe, converts probe gap variation into linear voltage signal. It compares measured value with preset alarm and trip thresholds, triggers relay output when exceeding limits. It also detects cable open circuit and short circuit faults for loop health diagnosis.

Certification: ATEX, CE

Oscillator drive circuit, signal conversion board, threshold comparison circuit, relay output assembly, status indicator. Common faults: zero point drift, excitation signal loss, false alarm, relay contact burnout.
