Product Introduction
The Bently Nevada 3500/40M-01-00 Proximitor Monitor is an advanced condition monitoring module designed specifically for use in the Bently Nevada 3500 Series Machinery Protection System. This module processes input from proximity probes and delivers high-resolution vibration, position, and thrust measurements for critical rotating machinery such as turbines, compressors, pumps, and motors.
Equipped with advanced signal conditioning and diagnostics, the 3500/40M delivers real-time monitoring of shaft dynamics to help identify wear, misalignment, or imbalance long before they lead to catastrophic equipment failure. It interfaces seamlessly with Bently Nevada’s proximity transducers, including the industry-leading 3300 XL series, and offers easy integration into plant-wide monitoring strategies.
