Product Description
Bently Nevada 133396-01 Overspeed Detection I/O Module
Product Overview
- The Bently Nevada 133396-01 is an Overspeed Detection I/O Module designed for use with the Bently Nevada 3500 Series Machinery Protection System, specifically for critical overspeed protection in rotating machinery such as turbines, compressors, and generators in power generation, oil and gas, and industrial applications. Part of the 3500/53 Overspeed Detection System, this module interfaces with proximity probes or magnetic pickups to monitor shaft rotational speed and initiate shutdowns when overspeed conditions are detected, preventing catastrophic equipment failure.
