Bently Nevada 133388-02D 3500 Tachometer Module

The Bently Nevada 133388-02D 3500 Tachometer Module is a two-channel tachometer module for the 3500 Machinery Protection System that accepts two independent tachometer inputs from proximity probes or magnetic pickups to monitor shaft speed and related dynamics. Each channel provides speed data up to 250,000 RPM (configurable) with a 10 ms update rate and 0.1 RPM resolution, and it can relay conditioned Keyphasor signals to the 3500 rack; it also features a peak-hold function to store the highest speed, highest reverse speed, or number of reverse rotations, depending on channel type. Outputs include 4-20 mA analog, relay contacts, and digital communications to integrate with plant controls and data systems.
