Backed Semiconductor Half-Bridge and Full-Bridge Strain Gages are a range of semiconductor backed bridged strain gages. The gages are installed on a flexible insulated circuit with easy to solder pads which can be bent without hurting the gage and will perform like a foil gage except that the resistive change is 30 to 55 times greater.

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. This reduces the transverse gage factor to 42. The average GF for the half bridge would be 91.
Our Full-Bridge Backed Gages are constructed using four thermally matched gages bonded to a backing.

Backed bridged gages are available in three styles: Bending, Load and Torque

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 Backed Gages are constructed using two thermally matched gages applied 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. This reduces the transverse gage factor to 42. The average GF for the half bridge would be 91.
