Measuring principle
The plate ring tension sensor utilizes the elastic deformation of an elastic body under external force to cause a change (increase or decrease) in the resistance of a strain gauge attached to its surface. This change in resistance is then converted into an electrical signal (voltage or current) by a corresponding measuring circuit, thereby completing the force measurement process.
