The best possible counter measure in this case is the use of self-compensated strain gauges. The temperature behavior of these strain gauges is adapted to a specific material so that they compensate for the apparent strain (and therefore the temperature-induced expansion of the measuring body).

how sensors work - strain gauge

A typical example for a strain gauge of the type used for measuring force in industrial environments is 15 mV/V at 1000 pounds. That is, at exactly 1000 pounds applied force (either compressive or tensile), the bridge will be unbalanced by 15 millivolts for every volt of excitation voltage. Again, such a figure is precise if the bridge circuit is full-active (four active strain gauges, one in ...

The gauge factor is defined as the ratio of fractional change in electrical resistance to the fractional change in length (strain). (The gauge factor for metallic strain gauges is typically around 2.) Small Changes in Strain. We set up a strain gauge load cell and measure that change in resistance and all is good, right? Not so fast.

Fatigue testing - Wikipedia

Deze pagina vertalen

Fatigue testing is a specialised form of mechanical testing that is performed by applying cyclic loading to a coupon or structure. These tests are used either to generate fatigue life and crack growth data, identify critical locations or demonstrate the safety of a structure that may be susceptible to fatigue. Fatigue tests are used on a range components from coupons through to full size test ...
