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.
Claims20
A method of attaching a sensor to a device (1) so as to dilute the strain to which the sensor is exposed and hence ensure the sensor is always operating in its optimum range, comprising the steps of
- forming a platform (2) on the device (1) for mounting the sensor on;
- forming a channel (3) in the surface of the device (1) which extends entirely around the platform (2);
- and
- mounting a sensor on said platform (2).
A method of attaching a sensor to a device (1) so as to dilute the strain to which the sensor is exposed and hence ensure the sensor is always operating in its optimum range, comprising the steps of:
- forming a platform (2) on the device (1) for mounting the sensor on;
- forming a channel (3) in the surface of the device (1) which extends entirely around the platform (2), wherein the channel (3) is machined into the device (1);
- and
- mounting a sensor on said platform (2).
An apparatus comprising:
- a device (1) having a platform (2) formed thereon;
- a channel (3) which extends around said platform (2);
- and
- a sensor mounted on said platform.
