The ProTech 203 Overspeed Protection System monitors three individual magnetic pickups (MPUs) to provide overspeed protection for steam and gas turbines and other prime movers.

9907-147 Data sheet
|
The system replaces mechanical overspeed devices, especially in high-speed applications (above 10 000 rpm) when a mechanical overspeed device becomes unreliable Ease of calibration and testing, accuracy, and repeatability are the hallmarks of this system.
|
|
The ProTech device is unlike mechanical overspeed devices which equire considerable trial and error to set the overspeed trip setpoint. Because it uses digital speed-sensing technology, the ProTech device's setpoint is configured simply by programming the value from the touch panel on the front.
|
|
To insure its accuracy and functionality, each of the three speed-sensing units can be individually tested while the prime mover is running, using the integral frequency generator. A key lock prevents programming and testing by unauthorized personnel.
