How Does a Strain Gauge Load Cell Work? Load Cell Central

A load cell is a type of transducer, which is a device that converts energy from one form to another. Specifically, load cells are force transducers, converting the kinetic energy of a force such as tension, compression, pressure, or torque into a measurable electrical signal. The strength of the signal changes in proportion to the force applied.
