The same circuit also can be used with a semiconductor strain-gauge sensor and high speed digital voltmeter. If the DVM sensitivity is 100 microvolts, the current source is 0.44 milliamperes, the strain-gauge element resistance is 350 ohms and its gauge factor is 100, the resolution of the measurement will be 6 microstrains .
The Wheatstone Bridge Circuit. The Wheatstone bridge can be used in various ways to measure electrical resistance: For the determination of the absolute value of a resistance by comparison with a known resistance. For the determination of relative changes in resistance. The latter method is used with regard to strain gauge techniques.
A strain gage with a GF of 2 exhibits a change in electrical resistance of only 2 (500 x 10 -6) = 0.1%. For a 120 Ω gage, this is a change of only 0.12 Ω. To measure such small changes in resistance, strain gage configurations are based on the concept of a Wheatstone bridge.

On substituting all the resistors of the Wheatstone bridge circuit with four active strain gauges, we get a full-bridge arrangement. This configuration enables large outputs of strain-gage transducers, improves temperature compensation and offers even greater sensitivity.
A wheatstone bridge typically has 4 strain gauges (see diagram above), of which 2 are under compression (C) and 2 are under tension (T). A circuit is formed by joining the strain gauges together end to end to create a loop in this order. C1 ↔ e ↔ T1 ↔ f ↔ C2 ↔ g ↔ T2 ↔ h ↔ C1. If point ‘e’ is connected to a positive supply ...
Dec 13, 2004 · Bridge Excitation Techniques. A Wheatstone bridge is usually employed in strain-gauge sensors based on foil, thin film, or thick film. The Wheatstone bridge converts the gauge's strain-induced resistance changes into a differential voltage (Figure 1).
Apr 2, 2024 · The Wheatstone Bridge is one of the most common and simplest bridge network / circuit, which can be used to measure resistance very precisely. But often the Wheatstone Bridge is used with Transducers to measure physical quantities like Temperature, Pressure, Strain etc.
