Resilient Weight Sensors: Utilizing strain gauge principle, they calculate the weight of an object by measuring the resistance value changes on the strain gauge. Common resilient weight sensors include sheet strain gauges and beam strain gauges.
Load Cell: Utilizes the piezoresistive effect to calculate the weight of an object by measuring the resistance value change of conductive materials. Common types of piezoresistive load cells include thin-film load cells and silicon load cells, etc.
The working principle of weight sensors can be divided into various types, including resistive strain gauge, capacitive, and electromagnetic, among others. Among them, 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 applied to the elastic body, it undergoes slight deformation, causing a change in the resistance value of the strain gauge. By measuring the resistance value change, the weight of the object can be calculated.
Weighing sensors have extensive applications across various fields. In the industrial sector, they are commonly used for material weighing, goods distribution, and production process control. In the commercial domain, they are frequently employed for product weighing and pricing in supermarkets and shopping malls. In healthcare, they are often used for monitoring and controlling the weight of medical equipment and beds. Additionally, weighing sensors can be applied in transportation, agriculture, environmental monitoring, and other areas.
