Abstract

A circular shaft having a platform formed on it by machining a circular flat into the surface of the shaft. A channel extends around the periphery of the circular flat with a depth in the range of 10 to 15% of the diameter of the shaft and in the range of 30 to 50% of the width/diameter of the platform. The width of the platform is 4 to 7% of the diameter of the shaft. A sensor is mounted on the platform, whereby the formation of the platform and surrounding channel reduces the strain arising in the device which is transferred to the sensor.
