Description
Description
The Bently Nevada 3300/35-03-02-02-01-00 is a 6-channel Temperature Monitor designed for the 3300 Series rack system. This module provides continuous, high-reliability monitoring of multiple temperature points in critical rotating machinery, such as turbines, compressors, and large motors. By comparing sensor inputs against user-defined alarm setpoints, the module facilitates predictive maintenance and provides essential machinery protection by triggering relay outputs during abnormal temperature conditions.
Features
- Six independent monitoring channels for high-density temperature data acquisition.
- Compatible with standard industrial RTDs (Pt100, Pt1000) and thermocouples (J, K, T types).
- Provides proportional 4 to 20 mA and 1 to 5 VDC outputs for integration with external control systems.
- Integrated relay outputs for Alert and Danger alarm conditions.
- Front-panel LED indicators for quick status verification of OK, Bypass, Alert, and Danger states.
Applications
- Bearing temperature monitoring in rotating equipment.
- Stator winding temperature sensing for large motors and generators.
- Casing temperature monitoring for industrial compressors and turbines.
- General-purpose multi-point temperature data acquisition in process plants.
