The Bently Nevada 3300/35-02-02-01-00-00 is a 6-channel Temperature Monitor module engineered for integration into the 3300 Series rack-based monitoring system. This module provides continuous, high-reliability monitoring of critical temperature points in industrial rotating machinery, including turbines, compressors, and large motors. By processing inputs from RTDs or thermocouples and comparing them against user-configurable alarm setpoints, the unit facilitates proactive machinery protection and predictive maintenance.
Features
Six independent monitoring channels for multi-point temperature data acquisition.
Compatibility with standard RTDs (Pt100, Pt1000) and thermocouples (J, K, T types).
Integrated relay outputs for Alert and Danger alarm conditions.
Proportional analog outputs (4 to 20 mA and 1 to 5 VDC) for external integration.
Front-panel LED indicators providing real-time status for OK, Bypass, Alert, and Danger conditions.
Applications
This module is specifically designed for monitoring thermal conditions in critical assets, including:
Bearing temperature monitoring for large rotating equipment.
Stator winding temperature tracking in generators and motors.
Casing temperature monitoring for compressors and turbines.
