| 摘要 |
<p>The present invention relates to an apparatus for generating an electric signal corresponding to a force exercised thereon, e.g. a force arising out of the tension in a thread, preferably the tension in a thread in a loom or sewing machine, a mechanically bendable, tongue-like plate (1) being positioned in the path of the thread (14) in order to be bent by the thread (14) in correspondence to the force exercised in the thread, and at least one film resistor (R1, R2) being disposed on the plate (1) and being coupled into an electronic circuit for generating a signal corresponding to the mechanical action of the plate (1) to which the film resistor (R1, R2) is subjected on bending of the plate (1), and the path of the thread (14) past the plate (1) being substantially constant.</p> |
