High-Capacity Temperature Monitoring for Reliable Equipment Protection
The Bently Nevada 3500/65-02-00 16-Channel Temperature Monitor is a powerful monitoring solution engineered for the Bently Nevada 3500 Machinery Protection System. Designed to provide continuous thermal monitoring of critical rotating equipment, this module accepts both resistance temperature detector (RTD) and isolated-tip thermocouple (TC) inputs across 16 independently configurable channels. By comparing real-time temperature measurements against programmable alarm thresholds, it helps operators detect abnormal thermal conditions early, improving equipment reliability and reducing the risk of unexpected shutdowns.
The 3500/65-02-00 configuration features an RTD/Isolated Tip Thermocouple I/O Module with External Terminations and no hazardous-area approval option. Its external termination design simplifies field wiring and maintenance, making it an excellent choice for industrial facilities seeking flexible installation, precise temperature measurement, and seamless integration with the complete Bently Nevada 3500 monitoring platform.
