Product Overview

The Bently Nevada 330193-09-20-10-00 is a specialized 8mm proximity sensor designed for the 3300 XL transducer series, optimized for high-precision machinery health monitoring. This non-contacting displacement probe measures the gap between the sensor face and a rotating shaft to provide critical data on radial vibration and axial position. Engineered to comply with API 670 standards, this transducer is a fundamental component of Turbine Supervisory Instrumentation (TSI). This specific configuration features a 3/8-24 UNF thread with a 0.9-inch unthreaded length and a 2.0-inch total case length, providing a versatile mounting profile for industrial bearing housings.

Hardware Configuration and Technical Metrics

Industrial Utility and Strategic Applications

This proximity probe is a cornerstone for the protection of high-speed rotating assets in the power generation, petrochemical, and oil and gas industries. It is primarily used to monitor radial vibration on machines with fluid-film bearings, such as steam turbines, centrifugal compressors, and large industrial motors. By providing a deterministic signal to a Bently Nevada 3500 monitoring rack, the 330193-09-20-10-00 allows for the early detection of mechanical faults including shaft unbalance, misalignment, and oil whip. Additionally, its rugged armored design ensures it can withstand the high-temperature and chemically aggressive environments typical of machine internal casings, making it an essential tool for proactive predictive maintenance and automated safety interlocks.
