BENTLY 3500/42 128229-01 Vibration Monitoring Module

BENTLY 3500/42 128229-01 Vibration Monitoring Module

Product Description
Bently Nevada 3500/42 128229-01 is a 3500/42M Proximitor Seismic Monitor Module used in the 3500 Machinery Protection System. It is designed for continuous vibration and position monitoring of critical rotating machinery. The module receives signals from proximity probes, seismic sensors, and velocity sensors, processes vibration data, and provides alarm monitoring and machinery protection functions.

The 128229-01 is commonly configured as a Prox/Seismic I/O Module with internal terminations for the 3500/42M system.
