Introduction
The component with part number 3500/62-01-00 163179-03 is a specialized monitoring module within the Bently Nevada* 3500 Machinery Protection System. This part number refers to the 3500/62 Dual Channel Temperature Monitor.
This module is specifically designed to monitor temperature by accepting signals from up to two Resistance Temperature Detectors (RTDs). It converts the RTD resistance into engineering units (e.g., °C or °F) and provides continuous surveillance and protection based on programmable alarm setpoints. It is a key module for preventing machinery damage due to overheating in bearings, motors, and other critical components.
*Bently Nevada is a part of Baker Hughes.

Application Scenarios
The 3500/62 Temperature Monitor is deployed to protect machinery from damage due to excessive heat. Key application scenarios include:
Bearing Temperature Monitoring:
The most common application. RTDs are embedded in bearing housings to monitor the temperature of journal or thrust bearings in turbines, compressors, pumps, and motors. An alarm or shutdown is triggered to prevent bearing wipe.
Motor Winding Temperature Monitoring:
Used to monitor the temperature of stator windings in large electric motors using embedded RTDs, protecting the motor insulation from thermal degradation.
Lube Oil and Process Fluid Temperature:
Monitors the temperature of lubrication oil, seal oil, or other critical process fluids to ensure they are within safe operating limits for proper viscosity and cooling.
Integrated Machinery Protection:
Works in conjunction with other 3500 modules (like vibration and position monitors) to provide a comprehensive protection scheme. A high-temperature event can trigger an alarm or a Danger shutdown to protect the machine.
General Purpose Temperature Monitoring:
Can be used to monitor any critical temperature point on a machine where an RTD is installed.
Typical Machinery and Parameters Monitored:
Turbines & Compressors: Bearing Metal Temperature, Lube Oil Temperature
Pumps & Motors: Bearing Temperature, Motor Winding Temperature
Gearboxes: Bearing Temperature
Generators: Bearing Temperature
