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.

Technical Specifications

Installation Guidelines

• Ensure the 3300 rack is powered down before inserting or removing the monitor module to prevent electrical damage.
• The module must be seated firmly in the rack slot to ensure proper backplane communication and power distribution.
• Use shielded cabling for all sensor inputs to minimize EMI/RFI interference in industrial environments.
• Ensure proper grounding of the 3300 rack chassis to a common plant ground.
• Handle with standard ESD precautions; avoid touching the module's backplane connector pins.
