EMD Speed Sensor description/theory of operation
Function of the speed sensor is to detect the shaft speed and the direction of rotation. The sensor is
mounted to the endcover of a Danfoss motor and senses the speed from a magnet that is rotating inside
the motor. Because of the digital output signals for speed and direction and a non speed dependent
output voltage level, the sensor is ideal for high and low speed measurements.
The speed sensor is designed for rugged outdoor, mobile or heavy industrial speed sensing applications.
The detection of the speed is contactless. It is a plug-and-perform device that does not need any
calibration or adjustments.
