Magnetic pickups are used to control the speed of a prime mover, speed controls compare actual speed to desired, or set, speed.

Speed Sensing Magnetic Pickups
The speed sensor most often used to detect prime mover speed is the magnetic pickup (MPU). When a magnetic material (usually a gear tooth driven by the prime mover) passes through the magnetic field at the end of the magnetic pickup, a voltage is developed. The frequency of this voltage is translated by the speed control into a signal which accurately depicts the speed of the prime mover. These field-verified and compatible speed sensors provide a complete turbine control solution when combined with our turbine controllers and actuators.
