Bently Nevada’s 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 Standards 670 and 612 pertaining to overspeed protection.

3500/53 modules can be combined to form a 2-out-of-2 or 2-out-of-3 (recommended) voting system.

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

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.

Use for any input above 0.0167 Hz (1 rpm for 1 event/revolution).

Minimum signal amplitude for triggering is 1 volt peak-to-peak.

Under and Over Alert levels (setpoints) can be set for speed.

In addition, a Danger (Overspeed) setpoint can be set for speed. All alarm setpoints are set using software configuration. Alarms

are adjustable and can normally be set from 0 to 100% of full-scale of speed full-scale range.
