Speed Sensor Inputs

To sense speed, each ProTech-GII module (A, B, C) accepts a signal from a speed sensor mounted on a

gear connected to the turbine rotor or engine crankshaft. Speed sensors may be any of the following:

 Passive magnetic pickup unit (MPU)

 Active proximity probe

 Eddy current probe
