135313 01 is an Electronic Overspeed Detection System manufactured and designed by Bently Nevada as part of the 

3500/3 Series used to control the machinerycondition monitoring system The sstem ypicaly consists of speed sensors, a 

contol unit and output relys Sped sensors, such as magnetic pickups or proximnityprobes, are mounted near the 

rolating shaftor gear teth to continuouslymeasure sped These sensors generate electical pulses proportional to the 

rotational sped ofthe machine The pulses are then transmitted to the controlunit which processes the signals and 

compares them to predefined overspeed thresholds Modern overspeeddetection systems often incorporate Triple 

Modular Redundany (TIMR, where three independent Channels measure and veriy speed values to ensure high 

reliablity andminimize false trips.

Frequently asked questions：

1.What is the Bently Nevada 3500/53 Overspeed Detection System?
The Bently Nevada 3500/53 Overspeed Detection System is a highly reliable and advanced monitoring solution 

designed to detect and prevent excessive rotational speeds in critical rotating machinery. It is part of the Bently 

Nevada 350o Series Machinery Protection System and is primarily used in turbines, compressors, and generators
2.Why is Triple Modular Redundancy (TMR) important in overspeed detection?
TMR enhances system reliability by using three independent speed channels, ensuring that a single sensor failure 

does not trigger false trips or system malfunctions. The system makes a decision based on a 2-out-of-3 voting 

mechanism, allowing operations to continue even if one sensor fails.
3.What types of speed sensors are compatible with the 3500/53?
The system supports various sensor types, including proximity probes, magnetic pickups, and Hall-effect sensors. 

This flexibility allows it to be integrated with different machinery setups, ensuring accurate speed measurements 

across a range of industrial applications.
