The working principle of weight sensors is based on the piezoresistive effect or strain gauge principle. The piezoresistive effect refers to the change in the resistivity of conductive materials when subjected to pressure or gravity. The strain gauge principle means that when an object is subjected to external force, it causes a change in the resistivity on the strain gauge film. By measuring the change in resistivity, 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, electromagnetic, etc. Among them, the resistive strain gauge is a common and widely used type. It operates by attaching a strain gauge to an elastic body; when an object is applied to the elastic body, it undergoes minute deformation, causing the resistance value of the strain gauge to change. By measuring this resistance change, the weight of the object can be calculated.
