The device includes a long spindle (6) that can be pushed outwards. The spindle does not rotate and is held by a rotating nut (6.1). One end of the spindle butts against a sprung toothed plate (1), which is arranged against a measurement head (3) so that it can be linearly displaced. A pressure sensor (2) with an electronic amplifier plate is integrated in the measurement head casing.
