DEVICE FOR PART HEIGHT MEASUREMENT Russian patent published in 2013 - IPC G01B17/00 

FIELD: measurement equipment.

SUBSTANCE: device for part height measurement includes a base, a rod with a mounted frame with a holder, a piezoelectric converter with a probe and facilities for visual reflection of measurement, at the same time the piezoelectric converter is made in the form of a hollow body, in which a piezoelectric element is elastically mounted and pressed to the rear inner side of the body with the help of a spring, at the same time the piezoelectric element is equipped with two flat electrodes-contacts connected with a LATR supplying power, one is fixed electrode contact mounted between the piezoelectric element and the rear inner side of the body, and the second one is the movable electrode-contact mounted between the piezoelectric element and the probe, at the same time the device is equipped with an indicator of probe contact with a measured part, electrically connected with the power supply source.

EFFECT: increased accuracy of part height measurement and value of its wear.
