Product Overview

The Bently Nevada 21500-00-36-05-02 is a precision-engineered Proximity Probe Assembly, commonly referred to as a Proximitor. This non-contact sensor is a critical component in the Bently Nevada System 3500. specifically designed for the measurement of shaft displacement, shaft position, and keyphasor (rotational reference) in high-speed rotating machinery. The 21500-00-36-05-02 utilizes eddy current technology to detect the distance between the probe tip and a conductive metallic surface, typically the rotating shaft of a turbine, compressor, or motor.

Featuring a robust 11 mm diameter probe tip, this assembly is optimized for applications where space is limited or where a specific probe size is required for the sensor gap and frequency response. The 21500-00-36-05-02 is an integral part of the machinery protection system, providing the raw data necessary for the 3500 Series Monitor modules to calculate critical parameters such as eccentricity, shaft centerline position, and rotational speed. By integrating this probe into the monitoring system, operators can detect early signs of rubs, misalignment, and bearing wear, preventing catastrophic mechanical failure.
