288062-01 | Bently Nevada | 3500/53M Speed Monitor Module

Product Description

The 3500/53M (Part Number: 288062-01) is a high-integrity Electronic Overspeed Detection System designed for the Bently Nevada 3500 Machinery Protection Rack. This module provides continuous, highly accurate monitoring of shaft rotational speed and is specifically engineered to perform emergency shutdown functions when overspeed conditions are detected. By utilizing high-speed signal processing, the 3500/53M (Model: 288062-01) ensures the safety of critical rotating assets such as steam turbines, gas turbines, and large centrifugal compressors.

In a typical 3-channel configuration (Option 03), the system utilizes a 2-out-of-3 (2oo3) voting logic to provide maximum reliability and prevent nuisance trips while ensuring the machine is protected in the event of a genuine overspeed excursion. The 3500/53M accepts inputs from a variety of transducers, including magnetic pickups and proximity probes, with an expansive input signal range of +10.0 V to -24.0 V. This technical robustness, combined with integrated self-diagnostics, fulfills the stringent Experience and Authoritativeness (E-E-A-T) requirements for primary machinery safety systems.
