Bently Nevada 3500/65 145988-02 is a 16-channel temperature monitor for the 3500 TSI machinery protection system, supporting RTD and isolated tip thermocouple inputs for bearing and winding temperature monitoring.

Product Overview

Bently Nevada 3500/65 (145988-02) is a high-density temperature monitoring module belonging to the famous Bently Nevada 3500 Turbine Supervisory Instrumentation platform. It provides up to 16 configurable temperature channels, compatible with 3-wire / 4-wire RTDs and isolated tip thermocouples (Type K, J, E, T). It collects bearing metal temperature, stator winding temperature, lube oil temperature and other thermal data of rotating equipment, compares readings with user-defined Alert and Danger setpoints, and triggers alarm or trip logic through the rack relay modules. It supports TMR redundant configuration to reduce false trip risk and meets API 670 machinery protection standards. It is widely used in power plants, petrochemical and gas turbine units as a critical TSI spare part.
