Description

The Bently Nevada 3300/35-02-01-01-00-00 is a dedicated 6-channel temperature monitoring module engineered for integration into the 3300 Series machinery protection rack. This module provides critical, continuous thermal surveillance of rotating equipment, such as industrial turbines and compressors. By processing inputs from thermal sensors and comparing them against user-defined Alert and Danger setpoints, the monitor facilitates early detection of mechanical stress, supporting effective predictive maintenance and asset protection.

Features

• Six independent monitoring channels for high-density thermal data acquisition.
• Compatibility with standard industrial temperature sensors, including various RTDs and thermocouple types.
• Integrated alarm logic for Alert and Danger conditions with corresponding relay outputs.
• Front-panel LED indicators providing real-time status updates for OK, Bypass, Alert, and Danger states.
• Proportional output signals available for integration with external control or data logging systems.

Applications

This monitor is specifically designed for critical machinery applications, including:

• Bearing temperature monitoring.
• Stator winding thermal protection.
• Compressor and turbine casing temperature tracking.
• General-purpose multi-point temperature monitoring in hazardous or demanding industrial environments.

Technical Specifications

Installation Guidelines

• Ensure the 3300 rack system is powered down before inserting or removing the module to prevent electrical damage.
• Verify that the module is correctly seated in the designated rack slot to ensure proper backplane communication.
• Use appropriate shielded cabling for all sensor inputs to minimize EMI interference in industrial environments.
• Maintain proper ventilation within the cabinet to stay within the specified operating temperature range of -35 degC to +65 degC.
• Follow standard ESD protection procedures when handling the module to avoid damage to sensitive internal circuitry.

FAQ

What types of sensors does this monitor support?
