The tension load cell is a force sensor. They convert the kinetic energy of forces such as tension, pressure, pressure or torque into electrical energy; more specifically, the tension load cell is a measurable electrical signal. The strength of the signal is proportional to the applied force.The principle of the tension load cell is that deformation of elastomer under the action of external force, TM's resistance strain gages stick on the elastomer, resistance strain gauge deformation, the tension load cell conduct to resistance value change (increase/decrease), and then through the corresponding measurement circuit convert the resistance change to electrical signals (voltage or current), so as to complete the process of external force transforms into electrical signal.
