Product Overview

The Bently Nevada 330104-00-11-05-02-00 is a high-precision 8mm proximity sensor designed for the 3300 XL transducer series. This non-contacting probe is engineered to measure the micro-distance between the sensor tip and a rotating shaft, providing essential data on vibration and mechanical positioning. Designed to meet the stringent API 670 standards, this probe serves as the primary detection element within a Turbine Supervisory Instrumentation (TSI) system. This specific configuration features a 3/8-24 UNF threaded body with a 1.1-inch unthreaded length and a 5.0-inch total case length, specifically designed for deep-insertion mounting in industrial machine casings.

Mechanical Monitoring and System Integration

This 8mm proximity probe is a critical component for monitoring the health of high-speed rotating assets such as steam turbines, centrifugal compressors, and large-scale industrial pumps. The 5.0-inch case length allows for precise positioning in thick-walled bearing housings commonly found in large-scale power generation equipment. It is primarily utilized to track radial vibration (shaft unbalance or misalignment) and axial thrust position (detecting rotor movement that could cause internal collision). By transmitting a deterministic signal to a 3300 XL Proximitor and subsequently to a 3500 series monitoring rack, the 330104-00-11-05-02-00 enables automated machinery protection and supports sophisticated predictive maintenance analytics to prevent catastrophic equipment failure.
