Product Overview

The Bently Nevada 3500/50-01-00-01 288062-02 is a dual-channel tachometer module designed for precision monitoring of rotating machinery. As part of the industry-leading 3500 Series platform, this module integrates seamlessly with Bently Nevada’s machinery protection systems to deliver real-time insights into shaft rotational speed, acceleration, direction, and peak speed events. By accepting inputs from proximity probes or magnetic pickups, the 288062-02 processes signals to generate actionable data, ensuring early detection of overspeed conditions and minimizing unplanned downtime .

Key features include a peak hold function that stores the highest speed, reverse speed, and number of reverse rotations, enabling operators to analyze transient events post-alarm. Its modular design allows easy integration into existing 3500 Series racks, supporting applications in oil and gas, power generation, and manufacturing. Compliance with API 670 and SIL-2 standards ensures reliability in safety-critical environments, while dual 4–20 mA outputs per channel facilitate seamless integration with distributed control systems (DCS) .
