Semiconductor Backed Half-Bridge Gages
Product Announcement from Micron Instruments
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.
Backed Gage are configured to measure Torque, Load and Bending Stress.
