Bently Nevada 330101-00-63-20-12-05 3300 XL 8mm Electrical Eddy Current Displacement Probe

Product Description

Bently Nevada 330101-00-63-20-12-05 is a 3300 XL 8mm eddy current proximity probe, the core sensing component of the 3300 XL machinery protection system. It adopts non-contact eddy current measurement principle. The model suffix codes define thread size, case length, cable length, armor type, connector and hazardous area certification. It forms a complete 3300 XL 8mm transducer system with matching extension cable and proximitor sensor. It outputs voltage signal proportional to the gap between probe tip and metal shaft surface for rotor radial vibration, shaft displacement and Keyphasor speed measurement. It complies with API 670 standard. Components are fully interchangeable without component matching or individual bench calibration, widely used for rotating machinery condition monitoring and protection.
