A load cell is a type of force transducer. It converts the kinetic energy of force into a measurable electrical signal.
A strain gauge load cell is comprised of a solid metal body (or “spring element”) on which strain gauges have been secured. When force is applied to a mounted cell, the body of the load cell is slightly deformed. In response to the body shape changes, the strain gauges also change shape, resulting in a change in the electrical resistance of the strain gauges.
When arranged in a Wheatstone Bridge this change in resistance can be measured as a voltage change. Since the change in output voltage is directly proportional to the force applied, the amount of force applied can be calculated.
