How Load Cells Work

Load cells operate by converting mechanical force into an electrical signal. This process is particularly precise in strain gauge load cells, which use a Wheatstone bridge circuit to measure resistance changes caused by deformation. The electrical signals generated by load cells vary with the applied force, and these signals are processed to provide accurate measurements. The Wheatstone bridge is crucial in this process, enhancing sensitivity and compensating for temperature variations, ensuring consistent accuracy. The processed data is then displayed through a weighing indicator, providing a clear and readable measurement of the applied force or weight.
