Product Description

Bently Nevada 3300/35 79492-01 Six-Channel RTD Temperature Monitor

Precise Multi-Channel Temperature Monitoring for Machinery Protection & Asset Condition Management

1. Product Overview

The Bently Nevada 3300/35 79492-01 is a six-channel resistance temperature detector (RTD) monitor, a key component of the 3300 Series machinery protection system, designed for real-time online temperature monitoring of rotating machinery critical parts (e.g., bearings, windings, gearboxes, lubrication systems). It accepts inputs from up to six 4-wire RTD sensors (Pt100 standard), features independent channel configuration, high-precision measurement, and configurable alarm thresholds (alert, danger) for early fault warning. Compatible with 3300 Series standard racks, it supports hot-swappable replacement and seamless integration with 3300 system monitors, widely used in power generation, oil & gas, petrochemical, and heavy manufacturing for machinery over-temperature protection and predictive maintenance.
