Therefore, modern detection calculation is often adopted, such as high-precision sensor combined with software programming, but in the process of detecting by using the sensor, due to the specificity of a processing device, a special sensor clamp is required to be used for clamping, fixing and installing the sensor, so that the sensor can always keep parallel to a detection surface and unchanged in height along with the rotation of a processing tool.
