Introduction: With the advent of the Industry 4.0 era, the field of industrial automation in China has witnessed rapid development. From manual control, we have gradually and accurately controlled and transformed our equipment. Among these, the more precise control of Jondo requires the control of various types of high-precision sensors. The force Sensor is one of them. 1.

The load cell (resistance strain gauge), like the load cell, is also composed of an elastomer, a strain gage, a bridge, and other components. The basic principle is that when the sensor body is subjected to a force, the elastic body will be elastically deformed. The strain gauges will also be deformed, and the internal bridge will sense this deformation and output the signal. The significant difference with the load cell is that the reaction accuracy is slightly lower than that of the load cell, but the size and size of the size can be customized much more flexible than the load cell. Force sensors mainly include pressure sensors, tension sensors, multi-dimensional force sensors and so on.
2. Load cell application case
The main applications of force measuring sensors are: Widely used in metallurgy heavy industry, petrochemical industry, light industry and textile, chemical, injection molding, medical, military, food and beverage, mobile phone manufacturing, and major scientific research institutes, colleges, transportation, energy, machinery Automatic process control in manufacturing, building materials and other industries, especially automotive, robotics, electronics, medical, injection molding and powder metallurgy and other mechanical equipment, automated production line equipment, etc.; for example, cold and hot press pressure detection, robot grip, button touch sensitivity Test, testing machine, wire rope tension and other installation space with a small force detection field.
3. Load cell selection method
(1) Determine the basic parameters such as the use of the environment, installation dimensions, range, accuracy and cable length;
(2) View application For sensor materials, cables, labels and other special requirements, can be customized according to the requirements, but also need to consider other additional force at the installation site, such as lateral force, bending force, distortion force.
(3) Consider the functions required for field application control, such as the use of analog outputs or communication interfaces;
(4) Whether there is any other lateral force during the force measurement, choose a suitable sensor structure.
