This strain gauge arrangement uses an active WSG which is positioned on the test object in a uniaxial
stress field. This WSG is joined by 3 passive resistors within the imc CANSAS module to form a full bridge.
The strain gauge can have a resistance value of 120 .
This arrangement does not come with temperature compensation. The strain is computed as:
