A number of different types of sensors are used within the engineering industry. Commonly, this includes sensors such as tension load cells, eddy-current sensors, and many other to monitor and keep track of laser displacement, pressure, vision, and color. Of course this is just the tip of the iceberg and all sensors vary in regards to their usages. The first bridge circuit-measuring device created for measuring electrical resistances, was originally invented by Samuel Hunger Christie. Subsequent to its release, most did not have interest until the English physicist; Sir Charles Wheatstone further developed and promoted it within the following year. Ensuing, these improvements and following a boost in popularity it became known as the Wheatstone bridge. The bridge circuit design, works similar to the original potentiometer. Mainly, it works by balancing two legs within the bridge circuit, consisting of one leg for the measurement of an unknown electrical resistance, while the ot...
