The wheatstone bridge network consists of four resistors r a r b r c and r x interconnected. A bridge with 2mvv sensitivity will deliver 2mv if the measurement is at full scale and the bridge is excited with 1v.

The basic circuit consists of four resistive elements which are connected together into a diamond shaped configuration.

Wheatstone bridge mvv. The output voltage is specified in mvv of excitation for a full scale pressure differential across the diaphragm. When the bridge is fully balanced the right side resistors identical to the left side resistors r1r3 and r2rx the voltage across the bridge is zero. Invented in 1833 by hunter christie the circuit was later studied by.

It is nearly always expressed in mvv. The wheatstone bridge is an electrical bridge circuit used to measure resistance. Single op amp differential amplifier the thevenin equivalent of the sensor is useful in calculating gain.

General wheatstone bridge illustrated below consists of four resistive arms with an excitation voltage v ex that is applied across the bridge. Given a sensor having 1 kw elements and a sensitivity of 10 mvv is being used. Signal conditioning wheatstone resistive bridge sensors 3 sig sig r2 r4 r1 r3 vo sig sig x r2 r4 r1r2 and r3r4 figure 2.

Excitation voltage v ex displaystyle vtextex is a known constant and output voltage v o textstyle vo is variable depending on the shape of the strain gauges. Wheatstone bridge strain gauge circuits are used extensively inside transducer to convert a mechanical strain into an electrical output signal. The gages are wired in a wheatstone bridge circuit including bridge completion resistors when needed so the pressure gage is electrically equivalent to a load cell.

Mvv millivolts per volt output signal it is an electrical signal which is proportional to the applied excitation voltage and is also referred to as a ratio metric or strain gauge output. If the ratio of the two resistances r b r a is equal to the ratio of the two r x r c then the voltage across bridge v b will be zero. A wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit one leg of which includes the unknown component.

The wheatstone bridge the wheatstone bridge is a familiar circuit for measuring resistance very accurately. The wheatstone bridge is a very useful circuit. The primary benefit of the circuit is its ability to provide extremely accurate measurements in contrast with something like a simple voltage divider.

A wheatstone bridge is a configuration of four balanced resistors with a known excitation voltage applied as shown below.
