Overview
The Bently Nevada 3500/65-01-01 is a 16-channel temperature monitor that provides precise monitoring by accepting resistance temperature detectors (RTD) and isolated tip thermocouple (TC) inputs. It conditions these inputs and compares them against user-programmable alarm setpoints to ensure high accuracy in various industrial environments.
Key Features
- The 3500/65-01-01 can be configured using the 3500 Rack Configuration Software for isolated tip thermocouples, as well as 3-wire/4-wire RTDs.
- For Triple Modular Redundant (TMR) configurations, the monitor uses two types of voting to guarantee accurate operation and minimize the risk of failures.
