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 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 (). A thermal insulation system is placed between the protective casing and the piezoelectric transducer and preferably includes at least one element () made of thermal insulating material, such as fiberglass, between the piezoelectric transducer and the support frame.
