Product Introduction
The Bently Nevada 330910-01-19-10-02-00 3300 NSv Proximity Probe is a precision-engineered proximity sensor developed for industrial machinery vibration and displacement monitoring applications. Part of the Bently Nevada 3300 NSv Proximity Probe System, this model offers highly accurate, stable, and repeatable measurements in harsh industrial conditions where space limitations and high reliability are essential.
The 330910 series is specifically designed for small shaft applications such as small turbines, compressors, pumps, and gearboxes, where accurate measurement of shaft vibration and position is critical for machine protection and predictive maintenance. The probe operates based on the Eddy Current principle, detecting the distance between the probe tip and the target metallic surface with exceptional linearity and temperature stability.
The 330910-01-19-10-02-00 model delivers high-frequency response, superior signal integrity, and full compatibility with the Bently Nevada 3300 NSv Proximity Transducer System. It is commonly paired with 3300 NSv Extension Cables and Proximitor Sensors to form a complete transducer assembly.
