ABSTRACT:
The measuring device comprises a body (1) whose end (1a) is secured to a rod (2) connected to a measuring instrument. A probe assembly (3,4,5) is provided with a feeler head (4a) and is secured to a lever (6) which rotates around a pin (8) in the body (1). The angular path of the lever (6) is limited by a stop (12) built into the body (1) and by a stop adjustable by means of an eccentric part (11a) in such a manner that the body (1) always takes the same position in each measuring direction on alternate measuring of two opposite surfaces lying in the same plane. A spring (9) urges the lever (6) towards its upper position. By this means, the measurement of the distance between opposite surfaces requires no calculation, i.e. addition or subtraction of measuring constants, thus making measurement easier and precluding errors in calculations.
