Description

The Bently Nevada 3300/35-04-02-01-00-00 is a specialized 6-channel temperature monitor module designed for integration within the 3300 Series rack-based monitoring system. This module provides essential oversight for rotating machinery, such as compressors and turbines, by continuously tracking thermal data from critical points. It is engineered to facilitate predictive maintenance and machinery protection through precise sensor input processing and automated alarm setpoint verification.

Features

• Six independent monitoring channels for versatile temperature tracking.
• Compatibility with standard industrial sensors, including RTDs (Pt100, Pt1000) and various thermocouple types (J, K, T).
• Integrated relay outputs for Alert and Danger alarm states.
• Proportional output signals (4 to 20 mA and 1 to 5 VDC) for external data logging and control systems.
• Front-panel LED indicators providing real-time status updates for OK, Bypass, Alert, and Danger conditions.

Applications

This module is typically deployed in power generation and petrochemical facilities to monitor temperature levels in critical assets, including bearing housings, stator windings, and equipment casings. It acts as a primary safety component in machinery protection systems to prevent catastrophic failure through early detection of thermal anomalies.

Technical Specifications

Installation Guidelines

• Ensure the 3300 rack is powered down before inserting or removing the module.
• Handle the module using proper ESD protection to prevent damage to sensitive internal circuitry.
• Verify that all field wiring is routed away from high-EMI sources to maintain signal integrity.
• Ensure proper grounding of the 3300 rack system per Bently Nevada site installation standards.
• Confirm that the input sensor type matches the module configuration before applying power.

FAQ

What type of sensors does this module support?

The 3300/35-04-02-01-00-00 is designed to support both RTDs (such as Pt100 and Pt1000) and standard thermocouples, including J, K, and T types.

What is the primary function of the relay outputs?

The relay outputs are configured to trigger automatically when temperature measurements exceed predefined Alert or Danger setpoints, allowing for immediate machine protection actions.
