Speed Sensor
An optional speed sensor for direct measurement of speed is available.
A special magnetic ring is pressed onto the outside diameter of the cylinder block and a Hall effect sensor
is located in the housing. The sensor accepts supply voltage and outputs a digital pulse signal in
response to the speed of the ring. The output changes its high/low state as the north and south poles of
the permanently magnetized speed ring pass by the face of the sensor. The digital signal is generated at
frequencies suitable for microprocessor based controls. The sensor is available with different connectors.
