SENSITIVE ELEMENT Russian patent published in 2019 - IPC G01L1/22 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment, in particular, can be used for reliable and accurate measurement of high-value forces in a wide range. Sensitive element comprises an elastic cylindrical rod, both ends of which are equipped with force-receiving elements in form of top and bottom covers with conic recesses of specified taper made on their inner surfaces, along which covers are pressed to upper and lower chamfers of specified taper, made on elastic cylindrical rod, smoothly mating with its cylindrical and end spherical surfaces, respectively, and multi-directionally located with interference in the recesses strain gauge compression wire and resistance strain gage expansion wire, wherein the resistance strain gage thread is made along the whole chamfer height, and the resistance strain gage thread is made at resistance strain gage places.

EFFECT: dynamic loads measurement in wide range with high accuracy and reliability, including high value.
