What is a load cell?
A load cell converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured. Strain gauge load cells are the kind most often found in industrial settings. It is highly accurate, versatile, and cost-effective. Structurally, a load cell has a metal body to which strain gauges have been secured. The body is usually made of aluminum, alloy steel, or stainless steel, which makes it very sturdy but also minimally elastic.
