Bently Nevada 3500/53M 286566-01+133396-01 Overspeed Detection Module

Product Introduction

The Bently Nevada 3500/53M Overspeed Detection Module (part numbers 286566-01 and 133396-01) is a critical safety and protection module designed for the Bently Nevada 3500 Series Machinery Monitoring System. Its primary function is to monitor shaft speed in rotating machinery and provide rapid overspeed detection to prevent mechanical failure.

Engineered for industrial applications, this module is used in turbines, compressors, and other high-speed rotating equipment where exceeding design speed could result in catastrophic damage. The 3500/53M module continuously monitors speed via proximity probes or other speed sensors and triggers alarms or shutdown sequences when predefined overspeed thresholds are exceeded. Its fast response, high reliability, and integration with the 3500 Series ensure that machinery remains protected under all operating conditions.
