The Bently Nevada 3300/35-03-02-02-01-00 is a dedicated 6-channel temperature monitoring module engineered for the 3300 Series rack-based system. This module provides critical, continuous surveillance of temperature parameters across rotating machinery, including industrial turbines, compressors, and large motors. By processing inputs from various temperature sensors and comparing them against user-defined alarm setpoints, it facilitates reliable machinery protection and enables proactive maintenance workflows.

Features

  • Six independent monitoring channels for high-density temperature data acquisition.
  • Support for diverse sensor types including RTDs (Pt100, Pt1000) and thermocouples (J, K, and T types).
  • Integrated relay outputs specifically configured for Alert and Danger alarm conditions.
  • Analog output support including 4 to 20 mA and 1 to 5 VDC proportional signals.
  • Front-panel LED indicators providing real-time status for OK, Bypass, Alert, and Danger states.

Applications

This module is typically deployed in power generation, petrochemical, and heavy manufacturing facilities to monitor bearing temperatures, stator winding temperatures, and equipment casing temperatures. It serves as a vital component in machinery protection systems, ensuring early detection of thermal anomalies that could lead to unscheduled downtime.

Installation Guidelines

  • Ensure the 3300 rack is powered down before inserting or removing the module to prevent electrical damage.
  • Verify that all field wiring is properly shielded and routed away from high-EMI sources to maintain signal integrity.
  • Confirm proper grounding of the 3300 rack system to the plant signal ground to minimize noise interference.
  • Ensure adequate ventilation around the rack assembly to maintain operating temperatures within the specified -35 degC to +65 degC range.
  • Handle with care to prevent electrostatic discharge (ESD) damage to the internal circuitry.

FAQ

What sensor types are compatible with this monitor?

This module supports RTDs (Pt100 and Pt1000) and common thermocouple types including J, K, and T.

What is the primary function of the relay outputs?

The relay outputs are designed to trigger external trip or alarm systems when measured temperatures cross the pre-configured Alert or Danger thresholds.

Does this module require special configuration?

The 3300/35-03-02-02-01-00 is a standard configuration unit; please refer to the Bently Nevada 3300 system manual for specific software configuration procedures and setpoint programming.
