Non-Contact Eddy-Current Proximity Probe for Machinery Protection
The Bently Nevada 30000-00-30-18-02 Probe Vibration Sensor is a non-contact eddy-current proximity probe designed for continuous monitoring of shaft vibration, shaft position, and rotor displacement in critical rotating machinery. It is used in condition monitoring and machinery protection systems to provide accurate measurements of shaft motion without contacting the rotating surface. Bently Nevada proximity probes are widely used in industrial asset protection systems for turbomachinery and other rotating equipment.
The 30000 series probes operate as part of a complete transducer system consisting of a proximity probe, extension cable, and Proximitor® sensor. Together, these components convert shaft displacement into a proportional electrical signal for machinery monitoring systems.
