ABSTRACT:
An instrument composed of a measurement head (1) and a fixed stop (2) which are connected by a body (3) formed of interchangeable extension pieces (4, 5), the instrument being intended to check the dimensions of bulky parts.
The two contact stops (12) of this instrument are offset at the end of two parallel measurement feelers (10, 11).
With each of these two contact members there is associated an instrument for measuring their inclination, which consists of an electronic clinometer (25, 26).
The two clinometers are connected to an apparatus (30) for reading the inclination of the two measurement feelers.
The inclination of one of the two measurement feelers (11) is adjustable by means of an operating screw (17).
In this way it is possible to reestablish parallelism of the measurement feelers when the instrument bends, upon measurements of large dimensions.
