Overview
The Bently Nevada 79492-01 is a Six-Channel Temperature Monitor module designed for the legacy Bently Nevada 3300 series machinery protection system. This analog assembly is specifically engineered to interface with Resistance Temperature Detectors (RTDs) to provide continuous thermal surveillance of critical industrial assets. It serves as a vital diagnostic tool for monitoring bearing metal temperatures, stator windings, and lubrication systems in high-speed rotating machinery. The unit combines precise temperature measurement with programmable alarm thresholds to protect against equipment failure caused by overheating.
