Product Description

The Bently Nevada 3500/42 assembled with 140471-01 main board and 176449-02 auxiliary board is a high-precision four-channel Proximitor and seismic monitoring module for the 3500 series machinery protection systems. As a core dynamic parameter acquisition unit, it supports simultaneous signal collection from proximity probes and seismic sensors, accurately measuring radial vibration, axial thrust position, eccentricity, differential expansion, velocity and acceleration of rotating machinery. It provides reliable real-time data and threshold alarm judgment for key equipment such as turbines, compressors and generators, serving as the core monitoring guarantee for unit safe and stable operation.

This industrial-grade monitoring module features independent four-channel signal processing design, supporting flexible configuration of multiple mechanical parameter monitoring modes. It integrates high-sensitivity signal conditioning and noise reduction circuits to effectively filter on-site electromagnetic interference and ensure high-precision data repeatability. The module supports user-programmable alarm and trip thresholds, with automatic fault judgment for sensor disconnection, signal overload and circuit abnormalities. Equipped with front-panel LED status indicators, it realizes intuitive working status feedback. Adopting standard 3500 rack hot-swap design, it supports online non-stop replacement. With industrial wide-temperature resistance and enhanced EMC anti-interference performance, it adapts to harsh industrial environments and supports 24/7 long-term continuous equipment condition monitoring.
