From Wikipedia, the free encyclopedia.

In many cases, the significance of measuring the unknown resistance is related to measuring the jembattan of some physical phenomenon such as force, temperature, pressure, etc. The Wheatstone bridge is the fundamental bridge, but there are other modifications that can be made to measure various kinds of resistances when the fundamental Wheatstone bridge is not suitable. Published in “Engineering Science and Education Journal”, volume 10, no 1, Februarypages 37— The concept was extended to alternating current measurements by James Clerk Maxwell in and further improved by Alan Blumlein around Breathalyzer Carbon dioxide sensor Carbon monoxide detector Catalytic bead sensor Chemical field-effect transistor Electrochemical gas sensor Electrolyte—insulator—semiconductor sensor Electronic nose Fluorescent chloride sensors Holographic sensor Hydrocarbon dew point analyzer Hydrogen sensor Hydrogen sulfide sensor Infrared point sensor Ion selective electrode Whextstone chemistry sensor Nitrogen oxide sensor Nondispersive infrared sensor Olfactometer Optode Oxygen sensor Pellistor pH glass electrode Potentiometric sensor Redox electrode Smoke detector Zinc oxide nanorod sensor.

Retrieved from ” https: The primary benefit of the circuit is its ability to provide extremely accurate measurements in contrast with something like a simple voltage divider. The desired value of R x is now known to be given as:. Some of the modifications are:.

This setup is frequently used in strain gauge and resistance thermometer measurements, as it is usually faster to read a voltage level off a meter than to adjust a resistance to zero the voltage.

At this point, the voltage between the two midpoints B and D will be zero. On the other hand, if the resistance of the galvanometer is high enough that I G is negligible, it is possible to compute R x from the three other resistor values and the supply voltage V Sor the supply voltage from all four resistor values.

The Wheatstone bridge illustrates the concept of a difference measurement, which can be extremely accurate.

Geophone Hydrophone Microphone Seismometer. First, Kirchhoff’s first law is used to find the currents in junctions B and D:.

The Kelvin bridge was specially adapted from the Wheatstone bridge for measuring very low resistances. One of the Wheatstone bridge’s initial uses was for the purpose of soils analysis and comparison. To do so, one has to work out the voltage from each potential divider and subtract one from the other. Views Read Edit View history.
