The plate-ring tension sensor utilizes the elastic deformation of an elastic body under the action of an external force, causing the resistance value of the resistance strain gauge adhered to its surface to change (increase or decrease). Then, through the corresponding measurement circuit, this resistance change is converted into an electrical signal (voltage or current), thereby completing the force measurement process.
