Abstract (en)
[origin: WO2009153013A1] The present invention relates to an attachment displacement sensor for use when mechanically measuring the change in length of a sample as a result of stretching. It also relates to a method for measuring the change in length of a sample by means of such an attachment displacement sensor, to a system for measuring the change in length of a sample with such an attachment displacement sensor, and to the use of such an attachment displacement sensor for measuring the change in length of a sample. The attachment displacement sensor comprises a body which is used to make contact with the sample. According to the invention, the body is rotatably mounted and arranged in such a manner that, if the sample is torn, it causes the body to rotate. As a result of the fact that the sample causes the body to rotate if torn, only a small amount of energy is transmitted to the attachment displacement sensor which is thus not overloaded or damaged.
