What is a load cell used for?

A load cell is primarily designed to measure the amount of force or weight applied to it. It does this by converting a physical force or load into an electrical signal, enabling accurate measurement of that weight or force. Load cells are widely used in various applications, including scales, industrial equipment, and material testing, where precise weight and force measurements are essential for monitoring and controlling processes.

The other options describe functions of different devices that do not pertain to the measurement of force or weight. For instance, converting electrical energy into mechanical energy pertains more to motors or actuators, measuring electrical resistance relates to ohmmeters or resistors, and regulating voltage levels is the function of power supplies or voltage regulators. Each of these roles is distinct from that of a load cell, which is specifically focused on providing accurate weight or force readings.
