The measuring range describes the space of a Sensor in which the object to be measured must be situated so that the specified technical data are satisfied. The extreme regions of this space are termed the start and end of the measuring range. Some sensors exhibit a space (cf. start of measuring range) between the measuring range and the Sensor. With contacting sensors, the measuring range is the distance between the mechanically minimum and maximum possible distance of the Sensor mounting to the Measurement object.
