What is a Load Cell?

A load cell is a type of transducer that converts the power to electrical energy. This transformation takes place in two steps; the force is first sensed by a tensile flap then converted into an electrical signal by changing the electrical resistance of a connected line. Weighing cells are commonly used in a number of common scenarios, including electronic weighing of trucks and train cars, and even in smaller home electronic weight scales.

When power is applied to a load cell, it deforms the strain gauge or the meters installed in the cell. A strain gauge is a device that changes shape depending on the amount of force applied. As more force is applied to the tension flap, it deforms longer and longer. Through its deformation, it changes the amount of electricity flowing through the enclosed line; This results in the production of an elevated level of electric current, generating electrical power from the first mechanical force applied to the load cell.

An electronic scale can provide a good example of how a load cell works. As an individual steps on the scale, his or her body weight interferes with the deformation gauges mounted in the scale. This, in turn, interferes with the electrical signals flowing through the scale. By measuring the interruption change from the baseline value scale, it is able to determine how much weight is being used for it, giving an accurate reading of how much the user weighs.

A load cell typically contains more than one strainer. This allows the power to be accurately detected and reshaped even though the application of the power is not continuous and lies at the center of a particular meter. In a multi-flap load cell, these gauges are usually arranged in a diamond formation known as a Wheatstone Bridge formation, which looks roughly like a two-dimensional square that has been tilted 45 degrees to one side. There are four strain gauges in a Wheatstone bridge configuration, with one of the gauges located in the middle of each side of the square.
