Metal foil type of strain gauges are superior to wire wound metal strain gauges because This change in resistivity is measured by a wheatstone bridge which is related to strain by a quantity called. gauge factor. In a single sensor strain gage. a metal foil pattern is mounted on a flexible substrate. which also serves to insulate the metal from the object under test.

A current is run through the foil pattern. The six wires are used in pairs for sense. excite. and measure. This experiment uses two active strain gages focusing on bending strain created. which is why the wheatstone half bridge. type ii (figure 2). was chosen.
The Main Theme Of This Application Note Is Aimed At Strain Appendix B Contains Schematics Of Many Of The Ways Strain Gages Are Used In Bridge Circuits And The Equations Which Apply To Them.
The objective of the experiment involves using the bending beam and the circuit bridge in the calibration of the strain gauge. The strain gauge can also measure displacement force by the strain in a fixed arm. generally described as a load cell. Strain gauge uses the practical form of wheatstone’s bridge to measure the strain developed by an element.
