DEVICE AND METHOD FOR MONITORING RESISTANCE STRAIN GAUGE GLUING QUALITY Russian patent published in 2019 - IPC G01B7/16 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measuring equipment, namely to strain-gauge measurement of objects deformation, and is intended for checking the quality of gluing resistance strain gauges (RSG) on products from any materials. Device comprises verifiable RSG 13, attached to strain gauge object 12, a resistor, a power supply, an amplifier connected to the band-pass filter, an internal half-bridge, intrinsically safe barriers, as well as a loading RSG appliance. A spring-loaded rod 4 is installed in the housing of the device; on one side the rod is fixed with cover 5 of the housing, on the other side it protrudes beyond the limits of the housing and is equipped with nozzle 6 with tip 7 of sticky material. Device comprises limiter in form of vertical plate 11, one part of which is fixed on housing, and other rests on object of strain gauge, rod is installed so that tip 7 is in contact with RSG, and with the possibility of displacement to the distance limited by the spring movement.

EFFECT: technical result consists in improvement of accuracy of determination of quality of adhesion of RSG on any materials.
