Hardware Specifications

Eddy-Current Displacement Measurement

The 330102-00-12-10-01-05 utilizes eddy-current sensing technology to monitor shaft movement without physical contact. When used with a compatible 3300 XL extension cable and Proximitor sensor, the probe generates a signal proportional to the distance between the probe tip and a conductive target surface.

The transducer system supports vibration monitoring, radial shaft position measurement, thrust position monitoring, eccentricity analysis, rotational speed measurement, and Keyphasor reference applications. Factory calibration is based on an AISI 4140 steel target, allowing predictable linear performance across the specified measurement range.

The armored cable construction provides additional mechanical protection in areas subject to abrasion, vibration, or cable routing hazards commonly encountered in turbines, compressors, pumps, and generators.
