Abstract
A touch probe () for applications in machine tools or measuring machines includes a support frame () with a protective casing (), and a movable armset () with a feeler () to touch a part to be checked (). The probe includes a detection device () with a laminar piezoelectric transducer () made of polymeric material, such as polyvinylidene fluoride, which is connected to the support frame and fixed at a bearing and locating area (), on which the movable armset rests in a position defined by an isostatic rest system (). Conditioning electronics () connected to the support frame include processing means for processing a force signal (M) provided by the detection device, comparing it with a threshold value (S) and generating a touch signal (T). The conditioning electronics include differential charge amplifiers () and a processing system () to dynamically vary the threshold value depending on the most recent values of the force signal detected.
