Description

The Bently Nevada 3500/65 Temperature Monitor is a high-density, 16-channel module designed for the 3500 Machinery Protection System. It provides continuous, reliable temperature monitoring for critical rotating machinery. The module accepts inputs from Resistance Temperature Detectors (RTDs) and thermocouples (TCs), comparing measured values against user-programmable alarm setpoints to ensure equipment safety and operational integrity.

Features

  • 16 independent temperature monitoring channels per module.
  • Compatible with both RTD and thermocouple sensor types.
  • Provides dedicated recorder outputs for each channel to facilitate external trending and diagnostic analysis.
  • Configurable via 3500 Rack Configuration Software for customized alarm logic and setpoints.
  • Available in both non-isolated and isolated versions (250 VDC channel-to-channel isolation) to mitigate electrical interference.
  • Designed for continuous online monitoring in accordance with API 670 standards.

Applications

The 3500/65 monitor is primarily used in industrial environments for critical asset protection, including large motors, turbines, compressors, and gearboxes. It is essential for detecting overheating conditions early, preventing catastrophic machine failure through integration with the broader 3500 rack system.

Installation Guidelines

  • Ensure the 3500 rack power is disconnected before installing or removing the module.
  • The module is designed for standard 3500 rack slots; ensure proper seating in the backplane connector.
  • Use shielded cabling for all sensor inputs to minimize electromagnetic interference (EMI).
  • Follow proper grounding procedures for the 3500 rack to ensure signal integrity and safety.
  • Handle with care to prevent electrostatic discharge (ESD) damage to the module circuitry.
  • Verify that the module configuration matches the physical sensor wiring (RTD vs. TC) within the 3500 Rack Configuration Software.

FAQ

What is the primary function of the 3500/65?

The 3500/65 is a temperature monitor that tracks up to 16 channels of temperature data from RTDs or thermocouples, providing alarm status and recorder outputs for machinery protection.

Does this module support both RTDs and thermocouples?

Yes, the module is designed to accept inputs from both RTDs and thermocouples. Depending on the specific version ordered, it can handle these inputs in isolated or non-isolated configurations.
