  • Product Name: 6-Channel Analog Rod Drop Monitor Module for Nuclear & Steam Turbine Applications

Product Description

The Bently Nevada 87199-01 is a specialized 6-channel analog component designed for Rod Drop Monitor applications. It is a critical part of the Bently Nevada machinery protection and condition monitoring ecosystem, specifically engineered for use in nuclear power plants and large steam turbines.
This module is responsible for monitoring the status of control rod drive mechanisms or similar critical actuation systems. It provides analog outputs that correspond to the position or status of the monitored rods, allowing the central monitoring system to verify proper rod insertion during a scram (emergency shutdown) event. The 87199-01 ensures that safety-critical systems are functioning as designed, providing an essential layer of protection and compliance in high-risk power generation environments.
