Fully radiate the common energy of resistance strain sensor, and flexibly match each component to assemble a force measuring sensor. The sensor is produced in the development of science and technology, and has also made a great contribution to the development of technology.
Tension sensor technology has matured in the coming months, and it has played a great role in many fields. With the development of the times, people's requirements for tension sensors are getting higher and higher. There are different factors in the development of tension sensors.
With the development of technology, there are more and more data to be measured, so a variety of sensors came into being. With these sensors, many measurement problems can be solved, such as the improvement of measurement accuracy, the measurement environment The limitation can be solved by the indirect measurement of the sensor. The generation of sensors in the development of science and technology has also made a great contribution to the development of science and technology.
Tension sensor principle: there are one or more elastic bodies that can be generated after being stressed, and a money point circuit composed of a resistance strain gauge that can sense this deformation amount, and a resistance strain gauge can be fixedly pasted on the elastic body and can conduct The strain sensor is composed of three parts: the adhesive of the dependent variable and the sealant for protecting the electronic circuit. After the force is applied, the strain gauge attached to the elastic problem will deform and cause resistance change. The resistance change will make the bridge unbalanced and output a power signal that changes linearly in proportion to the external force. change. Fully radiate the common energy of resistance strain sensor, and flexibly match each component, you can assemble a force measuring sensor.
However, the load cell is indeed affected by the ambient temperature. The strain-type tension sensor is mainly affected by the creep of the elastomer inside the sensor and the temperature of the sensor. We treat the two aspects as follows. The 50KN creep and endurance test machine uses a 100KN load cell, and the 100KN creep and endurance test machine uses a 200KN load cell. The purpose is to influence the creep of the sensor elastomer itself. drop to lowest. To minimize the heat transferred from the connecting rod to the sensor at high temperature, we use the method of lengthening and thickening the lower connecting rod and increasing and thickening the load cell connector to ensure that the temperature of the test force sensor is only higher than the environment when the furnace temperature is higher than 1000 ℃ The temperature is 4 degrees higher.
