Product Overview
The Bently Nevada 3500/50 Tachometer Module (133388-02) is a two-channel speed and phase monitoring module designed for use within the Bently Nevada 3500 Machinery Protection System.
This module provides accurate measurement of rotational speed, rotor phase reference, and rotor acceleration, offering critical data for both machine protection and condition monitoring applications.
The 3500/50 module accepts input signals from various types of speed sensors, such as magnetic pickups, proximity probes, and TTL-type sensors. It processes these signals to determine shaft rotational speed (RPM) and phase angle for synchronization with vibration or position measurements.
The 133388-02 rear I/O module connects the front monitor module to field sensors and outputs, ensuring reliable wiring and system integration.
