Bently Nevada 3500/42M 176449-02 Vibration / Position Monitor Module
Bently Nevada 3500/42M 176449-02 is a 4-channel vibration and position monitor module for the 3500 machinery protection system. It accepts signals from proximity probes and velocity transducers to measure shaft vibration, rotor position and differential expansion, providing alarm and trip protection for rotating equipment.

This module supports configurable measurement parameters and built-in sensor fault detection. It adopts hot-swap design, and can generate protection trip signals when the measured value exceeds threshold, widely used for vibration monitoring cabinet maintenance, spare parts replacement and rotating machinery protection system retrofit projects.
