Bently Nevada 3300/20 Dual Thrust Position Monitor

Product Introduction

The Bently Nevada 3300/20 Dual Thrust Position Monitor is a specialized module within the 3300 XL series, designed to monitor axial position (thrust) of rotating machinery shafts. By providing accurate dual-thrust position measurement, it ensures that machinery operates within safe axial limits, preventing damage to bearings, seals, and other critical components.

This module continuously monitors the shaft position using inputs from proximity probes, processing the signals to detect deviations, misalignment, or excessive thrust. Its real-time monitoring capability is essential in applications where axial movement directly impacts machine safety and reliability.

With a vertical size of 83 mm, the 3300/20 fits standard system racks and is widely used in turbines, compressors, and pumps. Its robust industrial design ensures accurate performance under vibration, temperature fluctuations, and other harsh conditions. The module is integral to predictive maintenance programs, helping operators identify and correct potential issues before catastrophic failures occur.
