As mentioned in the previous post, in order to relate the measured voltage difference across the bridge circuit to a strain measurement, we need a way of calibrating the system. In most systems, including the Prosig acquisition systems, this is done by including a high-precision shunt resistor across one of the legs in the bridge. For example, the following diagram shows a quarter-bridge circuit with a shunt calibration resistor, RS, across the bridge completion resistor R2.

The number of active arms in a strain gauge Wheatstone bridge is known as the bridge factor.

As a simple guide when selecting bridge factors the following rules apply; (more…)

The following application note describes the test and measurement process for the fatigue & durability testing and development cycle of an automotive suspension component, specifically a tie rod. The component had been known to fail at various intervals. An estimate of the predicted fatigue life of the component was required in order to assess the feasibility of its continued use and to see if a design change was required. The component under test is shown in Figure 1. The testing was carried out by a major automotive manufacturer. Strain gauges were used to monitor the strain levels.
