The Bently Nevada 3300/35-03-02-02-01-00 is a dedicated 6-channel Temperature Monitor module engineered for integration within the 3300 Series machinery protection rack systems. This module provides centralized, continuous thermal monitoring for critical rotating equipment, including turbines, compressors, and large motors, ensuring operational safety through real-time data acquisition and alarm processing.
Features
Six independent input channels capable of processing both RTD and thermocouple sensor data.
Provides proportional analog outputs (4-20 mA and 1-5 VDC) for external data logging or DCS integration.
Integrated relay logic for Alert and Danger alarm states to trigger machinery protection sequences.
Front-panel LED status indicators for immediate visual verification of OK, Bypass, Alert, and Danger conditions.
Designed for high-reliability operation in industrial environments with a wide operating temperature range.
Applications
This monitor is primarily utilized in power generation, petrochemical processing, and heavy industrial facilities to track temperature variations in:
Bearing housings and journal bearings.
Motor and generator stator windings.
Machinery casings and fluid processing lines.
