Description

The Bently Nevada 133388-02 is a 3500/50 Tachometer Module designed for the 3500 Machinery Protection System. This module is a four-channel device that accepts input from proximity transducers or magnetic pickups to measure shaft speed, rotor acceleration, and rotor direction. It is a critical component for monitoring rotating machinery, providing essential speed data for protection and control functions within the 3500 rack environment.

Features

  • Four-channel monitoring capability for speed and acceleration.
  • Compatible with standard Bently Nevada proximity transducers and magnetic pickups.
  • Provides proportional DC voltage outputs for speed and acceleration signals.
  • Supports programmable alarm setpoints for overspeed and underspeed protection.
  • Integrates directly into the 3500 rack backplane for power and communication.
