The Bently Nevada 3300/35-02-01-01-00-00 is a dedicated 6-channel Temperature Monitor module engineered for integration within the 3300 Series rack-based monitoring system. This module serves as a critical component for machinery protection, providing continuous thermal surveillance for rotating equipment such as turbines, compressors, and large motors.

Features

  • Provides six independent input channels for high-density temperature monitoring.
  • Supports a wide range of sensor types, including RTDs (Pt100, Pt1000) and thermocouples (J, K, T types).
  • Features integrated Alert and Danger relay outputs for automated machinery protection and shutdown logic.
  • Includes proportional +4 to +20 mA and +1 to +5 VDC outputs for external signal processing or data acquisition.
  • Equipped with front-panel LED status indicators for real-time monitoring of OK, Bypass, Alert, and Danger states.

Applications

This module is optimized for industrial environments requiring precise thermal management of critical assets. It is commonly utilized for monitoring:

  • Bearing temperatures in turbines and large compressors.
  • Stator winding temperatures in electric motors and generators.
  • Process fluid or casing temperatures where rapid detection of thermal anomalies is required for predictive maintenance.

Installation Guidelines

  • Ensure the 3300 rack is powered down before inserting or removing any monitor module to prevent electrical damage.
  • Handle modules with care to avoid damage to the backplane connector pins; ensure the module is fully seated in the rack slot.
  • Use appropriate shielded cabling for all sensor inputs to minimize electromagnetic interference (EMI) in industrial environments.
  • Verify that the sensor wiring matches the configured input type (RTD vs. Thermocouple) at the field wiring terminal block.
  • Maintain proper ventilation within the cabinet to keep the module within its specified operating temperature range.

FAQ

What sensor types are compatible with this module?

The 3300/35-02-01-01-00-00 supports standard RTD sensors (such as Pt100 and Pt1000) and common thermocouple types (J, K, and T), allowing for flexible integration with existing plant instrumentation.

How are alarms managed by the 3300/35?

The module performs continuous comparison of input signals against user-defined alarm setpoints. When thresholds are exceeded, the internal relays actuate to trigger Alert or Danger conditions, providing a reliable interface for plant control and safety systems.
