Product Description

The Bently Nevada 3500/50 (part number 133388-02) is a precision 2-channel tachometer module designed for the 3500 Machinery Protection System. This module accurately measures shaft rotational speed, rotor acceleration, and rotor direction by processing inputs from proximity probes or magnetic pickups. It plays a vital role in industrial asset management by comparing real-time measurements against user-programmable alarm setpoints, ensuring timely detection of abnormal operating conditions. Its ability to provide conditioned Keyphasor® signals to the 3500 rack backplane simplifies system architecture by often eliminating the need for a dedicated Keyphasor module.

Frequently Asked Questions

Q: Can the 133388-02 be used as a standalone overspeed protection system?

A: No. Bently Nevada tachometer modules are designed for monitoring and annunciation purposes. For critical overspeed protection, Bently Nevada offers dedicated systems (such as the 3701/55).

Q: Does this module eliminate the need for a separate Keyphasor module?

A: Yes, it can be configured to supply conditioned Keyphasor signals to the 3500 rack backplane, allowing other monitors to utilize the signal for phase reference information.
