The working principle of load sensors is based on the piezoresistive effect or strain gauge principle. The piezoresistive effect refers to the change in the resistance value of conductive materials when subjected to pressure or gravity. The strain gauge principle means that the resistance value on the strain gauge film changes when the object is subjected to external force. By measuring the change in resistance value, the magnitude of the pressure or gravity acting on the object can be calculated.
The working principle of weighing sensors can be divided into various types, including resistive strain gauge, capacitive, and electromagnetic, among others. The resistive strain gauge is a common and widely-used type. It works by attaching strain gauges to an elastic body. When an object is placed on the elastic body, it undergoes minute deformation, causing a change in the resistance value of the strain gauge. By measuring the resistance change, the weight of the object can be calculated.
