The main application of strain gauges is the manufacture of force and pressure transducers, particularly load cells. A load cell is a type of transducer that measures the mechanical load on an object by converting it to readable electronic signals. They are used in various industries such as automation, process control, biomechanics, equipment monitoring, building integrity analysis, bulk material weighing, testing, and quality control.

Modern load cells work using a combination of the Wheatstone bridge equation and the strain gauge. The Wheatstone bridge equation was developed in 1833 by Samuel Hunter Christie, and improved upon and popularized in 1843 by Sir Charles Wheatstone. Wheatstone bridge circuits illustrate the concept of a difference measurement. Today, load cells are usually made up of four strain gauges in a Wheatstone configuration.

It’s difficult to obtain an ideal accuracy if choosing range is not matched actual situation. For example, we don’t suggest use a 1000bar range of pressure sensor on measuring 1bar pressure, it would be better if you could use 10bar range instead of 1000bar. Therefore, choosing the right measurement range is very important and efficient for you. Three major factors must to be taken into account:
