Abstract
A sensor for detecting the stress profile of a thread that has moved. The sensor contains a signal generator, a thread guiding member and a body of resilient material. The signal generator is resiliently mounted in a vibration damping manner and in the manner of a cantilever in a body. Through this mounting arrangement the influence through mechanical action and also the influence of the thermal expansion caused by heat as a result of the heating up caused by the running thread are largely cancelled and thus measurement errors are avoided.
