Wheatstone Bridge Wiring Diagram. It can be used in all electronic circuits. As shown in the circuit diagram there are four resistances connected as a bridge circuit.
The output of a Wheatstone bridge is measured between the middle nodes of the two voltage dividers. 4-17a Is Known As A Wheatstone-bridge Circuit. The output voltage of the Wheatstone bridge circuit is expressed in millivolts output per volt input.
It was invented by samuel hunter christie in the year 1833 which was later popularized by sir charles wheatstone in 1843.
It can be used in all electronic circuits. R1 R2 R3 and R4. We also must connect the 5V output pin of the myDAQ to the top of the bridge to serve as the excitation voltage high and connect the Digital Ground DGND to. Notation of Wheatstone and b is another notation that is usually easier to understand by a person without a background in electrical or electronic engineering.
