BENTLY 3500/50 286566-02 Product Overview

Product Description

The BENTLY 3500/50 286566-02 is a tachometer module designed for the BENTLY 3500 machinery protection and condition monitoring system. It is a 2-channel module that accepts inputs from proximity probes or magnetic sensors to determine shaft speed, rotor acceleration, or rotor direction. The module compares these measurements with user-programmable alarm setpoints and generates alarms when setpoints are violated.
