<p>In a casing (20) a probe holder (34) is arranged bearing on a housing which is concentrically arranged about a central longitudinal axis (40) against a bearing body (26) and of which the configuration enables the fixing of at least one probe (38). The probe holder (34) is secured in the middle of an elastic disk (30) normal to the longitudinal axis (40) and of which the outer edge is secured to the casing (20). At least one electric switch (56) emitting a signal during the excursions of the probe (38) is added to the probe holder (34). </p> |
