Description
The Bently Nevada 3300/35-02-01-01-00-00 is a dedicated 6-channel temperature monitoring module engineered for the 3300 Series rack-based machinery protection system. This unit provides high-reliability, continuous thermal monitoring for critical rotating assets such as large industrial turbines, compressors, and motors, facilitating early detection of thermal degradation and supporting robust predictive maintenance strategies.
Features
- Six independent input channels capable of processing signals from RTDs (Pt100, Pt1000) and common thermocouple types (J, K, T).
- Integrated alarm management with dedicated Alert and Danger setpoints for each channel.
- Standard relay outputs for direct integration with plant safety and shutdown systems.
- Proportional signal outputs including +4 to +20 mA and +1 to +5 VDC for external data logging or DCS integration.
- Comprehensive diagnostic LED indicators for real-time status monitoring, including OK, Bypass, Alert, and Danger states.
Applications
This module is typically deployed in critical industrial environments where precise temperature tracking of bearings, stator windings, and machine casings is required to prevent catastrophic failure. It serves as a primary component in machinery protection systems where rapid response to temperature excursions is necessary for safe operation.
