Method for determination of length by means of comparison gauge involves snuggling of comparison gauge with pathway of device and signal is applied to comparison gauge and it receives response signal from comparing gauge

摘要

The method involves snuggling of comparison gauge (8) with the pathway of device. The signal is applied to the comparison gauge and it receives a response signal from the comparison gauge. The response signal is produced when the signal passes from the comparison gauge. The length is determined on the basis of response signal. Independent claims are also included for the following: (A) length measuring device; (B) and use of measuring device.
