Magnetic pickups (MPUs) are speed sensors that detect the speed of a prime mover, typically an engine or turbine. They are the communication link between your engine and a Woodward electronic governor control. The MPU speed sensor is installed next to a drive shaft gear made of a material that reacts to a magnetic field.
MPU Speed Sensor’s function is mainly to monitor whether the flywheel speed of the diesel generator set is fixed Reasonable working value range. To ensure the normal voltage and frequency of the diesel generator set. If the speed of the generator set is abnormal, then the voltage and frequency of the diesel generator set will not be normal, and other equipment will not be able to use it normally.
