Product Overview

The Bently Nevada 3500/65 Temperature Monitor 145988-02 provides critical temperature monitoring for rotating machinery. This module accepts RTD (100Ω Pt) and thermocouple inputs (J, K, T, E, R, S, B) with a range of -50°C to +750°C. It delivers ±1°C accuracy and <1 second response time for reliable bearing and process temperature protection.

Core Functionality

The 3500/65 monitor continuously tracks temperature inputs and generates alarms when thresholds are exceeded. Each channel features 4 independent alarms with programmable setpoints. It detects open-circuit sensor faults and provides configurable alarm outputs for shutdown or warning systems. The module supports both 2-wire and 3-wire RTD connections with automatic compensation.

Installation Guide

Power down the 3500 monitoring system before installation. Insert the 145988-02 module into an available slot in the 3500 rack. Connect RTD or thermocouple sensors to the rear terminal block. For 3-wire RTDs, connect all three leads. Configure alarm setpoints via the 3500 configuration software. Verify temperature readings against a known reference.

Engineering Advantages

This monitor provides ±1°C accuracy for precise temperature control. The 4 independent alarms per channel enable flexible protection strategies (alert, danger, and shutdown). Wide input type support (RTD + 7 thermocouple types) covers most industrial temperature sensors. Sub-1-second response ensures rapid detection of thermal events, preventing bearing or winding damage.
