DEVICE MEASURING FORCE Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: device measuring force has two elastic element arrange one inside another and measurement converter mounted on internal element. One of elastic elements is manufactured in the form of cylindrical case and the other one - internal element is made in the form of tube cylindrical part of which borders on parts of tube, one having external conical surface and the other one having internal conical surface. Angle between generating line of each conical surface and axis of cone is equal to 45 deg and conical surfaces and surfaces of cylindrical part of tube bordering on them have longitudinal cuts forming individual tabs. Primary measurement converter can be manufactured in the form of wire ring resistance strain gauge. Measurement converter can be fabricated in the form of two wire ring resistance strain gauges, one in compression zone , the other in tension zone. EFFECT: high measurement accuracy within wide range. 4 cl, 2 dwg
