DEVICE MEASURING FORCE Russian patent published in 1998 - IPC

FIELD: instrumentation engineering, converters of pressure, rarefaction, pressure difference, etc. SUBSTANCE: device measuring force has bearing plate and T-shaped force-absorbing member composed of central protrusion and transverse part which ends are directly joined to bearing plate forming together unitary structure. Surface of force-absorbing member carries dielectric substrate made from monocrystalline material with silicon resistance strain gauges placed into measurement bridge or differential electric circuit. Hole overlapped by dielectric substrate so that resistance strain gauges are positioned in zone of this hole is made close to base of central protrusion. Bearing plate and T-shaped force-absorbing member have different thicknesses with thickness ratio 2:1 and more. EFFECT: provision for high tensometric sensitivity, measurement accuracy, long-time stability and operational reliability within wide temperature range, simplified design and compactness. 5 cl, 4 dwg
