Description

The Bently Nevada 3500/60 Temperature Monitor Module is a critical component of the 3500 Series Machinery Protection System. This module is engineered to provide six independent channels of temperature monitoring, ensuring reliable data acquisition for industrial rotating machinery. It accepts inputs from Resistance Temperature Detectors (RTDs) and thermocouples (TCs), comparing these inputs against user-programmable alarm setpoints to trigger alerts or machine trips as required by plant safety protocols.

Features

• Six independent temperature monitoring channels per module.
• Universal input compatibility supporting both RTD and thermocouple sensors.
• Configurable alarm setpoints via 3500 Rack Configuration Software.
• Integrated recorder outputs for each channel to facilitate continuous trending and diagnostic analysis.
• Designed for continuous, high-availability online monitoring in compliance with API 670 standards.
• Model 3500/60-05-01 configuration supports specific input/isolation requirements for standard rack integration.

Applications

The 3500/60 module is widely utilized in heavy industrial environments for monitoring bearing temperatures, stator winding temperatures, and process fluid temperatures in critical assets such as steam turbines, gas turbines, compressors, and large electric motors.

Installation Guidelines

• Ensure the 3500 rack power is disconnected before inserting or removing the module to prevent electrical damage.
• The module must be seated firmly into the designated rack slot to ensure proper backplane communication.
• Use shielded twisted-pair cabling for all sensor inputs to minimize electromagnetic interference (EMI).
• Verify that sensor wiring polarity is correct for thermocouple inputs to prevent measurement errors.
• Maintain proper ventilation in the rack cabinet to ensure the module operates within the specified -30 degC to +65 degC range.
• Always follow standard ESD (Electrostatic Discharge) precautions when handling the module to protect sensitive internal circuitry.
