Bently Nevada 330905-00-08-10-02-CN 3300 NSv Proximity Probes

Product Introduction

The Bently Nevada 330905-00-08-10-02-CN 3300 NSv Proximity Probe is a high-precision, non-contact displacement sensor designed for advanced industrial machinery monitoring. As part of the 3300 NSv series, this probe is engineered for compact installations and small-shaft machinery, providing reliable measurement in areas where traditional probes may not fit.

Operating on the eddy current principle, the probe detects changes in the electromagnetic field caused by the proximity of a conductive target. This allows it to accurately measure static shaft position and dynamic vibration signals with high linearity. The 330905-00-08-10-02-CN is compatible with Bently Nevada 3300 NSv Proximitor modules, forming a complete monitoring system that meets API 670 machinery protection standards.

Its robust stainless steel housing and compact design make it suitable for turbines, compressors, pumps, and motors, enabling early detection of potential faults and supporting predictive maintenance programs.
