330101-00-12-05-02-05 | Bently Nevada Proximity Probes

Product Overview

The 330101-00-12-05-02-05 is a high-precision non-contacting transducer engineered by Bently Nevada for monitoring radial vibration and axial position on critical rotating machinery. As a cornerstone of the 3300 XL 8mm proximity probe system, this sensor converts the distance between the probe tip and a conductive target (such as a turbine shaft) into an accurate electrical signal. Designed to operate in high-temperature and high-pressure environments, it provides the essential data required for early machinery fault detection and automated safety shutdowns in accordance with API 670 standards.
