Piezo-Metrics Backed Semiconductor Half-bridge Gage SSGH

BACKED SEMICONDUCTOR STRAIN GAGES HALF-BRIDGE (SSGH) & FULL-BRIDGE (SSGF) Micron Instruments offers a wide range of semiconductor backed half and full bridge strain gages. Backed bridges are installed on a flexible high temperature insulator that can be bent around a one half inch radius without hurting the gage. Our Half-Bridge Backed Gages are constructed using two thermally matched gages bonded onto a backing which allows them to track each other. When used as one side of the bridge, they compensate each other thermally even when bonded since they both see the same thermal expansion and temperature. When both gages have a gage factor (GF) of 140 the transverse gage will normally see the Poisson’s effect, which for most steels is 0.3.
