Axial configured strain gages measure strain in one principal direction: along the long axis of the shim. They can be oriented in either the longitudinal or circumferential direction on the component being tested. Consult factory as shims may be pre-curved to fit surfaces with small radius curvatures.
These waterproof weldable gages are specifically designed to evaluate and monitor live-load stresses for railroad, bridge, and other structural applications and are 100% full water immersion tested. Standard gage resistances offered are 120Ohms & 350ohms nominal.
The precision foil gage is bonded to a stainless steel shim, pre-wired and protected with a molded water-proofing material. The stainless steel shim permits easy field installation with any conventional capacitive discharge spot welder.
Instrumentation cable and wiring options can be customized to your specifications. Custom gage sizes and resistance may be also available. Please see the table below for options.
