145988-02 | Bently Nevada | 3500/65 Temperature Monitor

Description

The Bently Nevada 3500/65 is a 16-channel temperature monitor used in industrial applications to monitor critical equipment. It accepts both resistance temperature detector (RTD) and isolated tip thermocouple (TC) temperature inputs. The monitor compares these inputs against user-programmable alarm setpoints.
