Description:

The Bently Nevada™ Electronic Overspeed Detection System for the 3500 Series Machinery Detection System provides a highly reliable, fast response, redundant tachometer system intended specifically for use as part of an overspeed protection system.

It is designed to meet the requirements of American Petroleum Institute (API) Standards 670 and 612 pertaining to overspeed protection. 3500/53 modules can be combined to form a 2-out-of-2 or a 2-out-of-3 (recommended) voting system.

The Overspeed Detection System requires the use of a 3500 rack with redundant power supplies.

The 3500 Overspeed Protection Module will support from 1 to 255 events per revolution with a maximum full-scale range of 99,999 rpm and a maximum input frequency of 20 kHz. Minimum input frequency for proximity transducers is 0.0167 Hz (1 rpm for 1 event/revolution) and for passive magnetic pickups is 3.3 Hz.

If the 3500/53 is added to an existing 3500 System the following firmware and software versions (or later) are required:

3500/20 Module Firmware – Revision G

3500/01 Software – Version 2.00

3500/02 Software – Version 2.03

3500/03 Software – Version 1.13

The use of redundant power supplies in a 3500 rack containing the Overspeed Detection System is required.
