Product Overview
The Bently Nevada 330980-71-05 3300 XL NSv Proximitor Sensor is a compact eddy-current sensor engineered for the 3300 XL NSv Proximity Transducer System. Designed for machinery with restricted installation space, it operates with compatible 3300 NSv Proximity Probes and 3300 NSv Extension Cables to provide accurate non-contact shaft displacement and vibration measurements.
This configuration features a 7.0 m (23.0 ft) system length, DIN-rail mounting, and the Multiple Approvals (05) option. Its compact housing, SpringLoc terminals, and enhanced immunity to electromagnetic interference make it an excellent choice for equipment upgrades, maintenance projects, and new installations.
