Product Overview
The Bently Nevada 3500/50 133388-02 is a Tachometer Module designed for precise rotational monitoring within the 3500 Series Machinery Protection System. It accepts input from proximity probes or magnetic pickups to measure shaft speed, rotor acceleration, and direction, providing reliable detection of overspeed, zero-speed, and reverse rotation conditions.
Engineers value the 3500/50 for its peak hold capabilities, front-panel LED indicators, and Keyphasor® output, which provides conditioned signals directly to the 3500 rack backplane without requiring a separate module. This module ensures machinery protection, predictive maintenance, and operational safety for turbines, compressors, and high-speed rotating equipment.
