Product Overview
The Bently Nevada 3500/50 Tachometer Module (133434-01) is a two-channel speed and phase monitoring module designed for the Bently Nevada 3500 Machinery Protection System.
It provides precise, continuous monitoring of rotational speed, phase reference, and acceleration of rotating machinery such as turbines, compressors, pumps, and generators.
This module is a key component in high-integrity protection and condition monitoring systems, providing accurate and stable measurements essential for overspeed protection, synchronization, and vibration phase analysis.
The 133434-01 model includes the rear I/O module, which works together with the front 3500/50 monitor to form a complete tachometer unit within the 3500 rack system.
