If a static load test is performed (1.) the strain gauge can be used in one direction (tension or compression) and exceed the yield limit. It still delivers a valid measured value in the plastic deformation zone. The maximum values for electrical strain gauges are specified as absolute strain in the strain gauge PDF catalog. The values for tension and compression are specified separately. For these tests, high strains between 1% and 10% are possible with HBM's foil strain gauges.
