The principle of a tension sensor is that the elastic body (elastic element, sensitive beam) undergoes elastic deformation under external force, causing the resistance strain gauge (conversion element) attached to its surface to also deform. After the deformation of the resistance strain gauge, its resistance value will change (increase or decrease), and then the corresponding measurement circuit will convert the resistance change into an electrical signal (voltage or current), thus completing the process of transforming the resistance. External forces are converted into electrical signals.

Considering the impact of strategic acceleration and air buoyancy on conversion in the usage site, the performance indicators of tension sensors mainly include linear error, hysteresis error, repeatability error, creep, zero temperature characteristics, and sensitivity temperature characteristics.

The advantages of tension sensors are high accuracy, wide measurement range, long lifespan, simple structure, good frequency response characteristics, and the ability to work under harsh conditions. They are easy to achieve miniaturization, integration, and diversification. Its disadvantage is that it has a large nonlinearity and weak output signals for large strains, but certain compensation measures can be taken. Therefore, tension sensors are widely used in automatic testing and control technology.

Construction industry: Tension sensors, small lifting equipment integrating motors, reducers, and wire rope drums, mostly equipped with walking carts, combined with single beam bridge or gantry cranes to form a complete lifting machinery. It is an important lifting equipment for industrial and mining enterprises, storage terminals, and other places. Due to the need to lift heavy objects of different tonnages during the use of cranes, a set of tension sensor systems is required to monitor the lifting capacity in real time, in order to determine the current working conditions and provide corresponding sound and light indications.   Overload state, full load state, overload state, etc.

Sports equipment: The tension machine in sports equipment adopts an electromechanical integrated design, mainly composed of tension sensors, emission devices, microprocessors, load drive mechanisms, computers, and color inkjet printers. High precision electronic speed regulating motors can be set with stepless testing speed. All integrated components are connected using plug-in connections. The floor standing models, shapes, and paintings fully consider the relevant principles of modern industrial design and ergonomics. The computer monitor displays the entire test process and curve, and the computer automatically transmits the test settings and data. Users can modify the test report according to their own requirements and output standard reports. By overlaying and analyzing the experimental curves of the group, it is possible to accurately grasp the quality control parameters. The multi-mode data query function allows managers to clearly grasp the development trend of quality control. Specially designed software functions enable experimenters to quantitatively grasp the state parameters of key points in the application process of experimental materials, accurately adjust the process and control production.
