A load cell is a kind of sensor that converts physical quantities into electrical signal output, and is mainly used to measure the pressure or tension of an object.
Its internal structure mainly consists of the following parts:
1. Elastic element: Usually made of metal material, it can be elastically deformed according to the size and direction of the force, so that the strain changes.
2. Strain Gauge: Installed on the surface of the elastic element, it can sense the strain change of the elastic element and convert it into an electrical signal output.
3. Support structure: It is used to fix the elastic elements and strain gauges to ensure that they are not disturbed by the outside world when they operate.
4. Signal scheduling circuit: The small electrical signal output by the strain gauge is expanded, filtered, linearized, etc., and the accurate force signal output is obtained. The above is the fundamental internal structure of the load cell, different load cells may also participate in other components such as ball guide mechanism, seals, protective shells, etc., to cope with different application environments and requirements According to their operating principles and measurement scale, there are many directions for the use of load cells.
Here are some directions for the use of load cells:
1. Industrial automation: load cells can be used to measure physical quantities such as force, pressure, and tension in robots, assembly lines, automated production equipment, etc., to complete intelligent control and monitoring.
2. Quality inspection: The load cell can be used to test the strength, toughness, hardness and other quality indicators of the product to ensure that the product meets the specifications.
3. Physical Training: Load cells can help athletes measure their strength, speed and agility to improve their training effectiveness and performance levels. 4. Medical equipment: load cells can be used in medical equipment, such as mattresses, wheelchairs, hearing aids, etc., to monitor the pressure, weight and posture of patients 5. Civil engineering: load cells can be used to measure the force of bridges, tunnels, dams and other structures to ensure their safety and stability. 6. Scope of research: load cells can be used in scientific research, such as material mechanics, aviation, geophysics, etc., to obtain accurate data and analyze In short, load cells are widely used in various fields, and with the continuous development of skills, the use of load cells will become more and more extensive and deep.

A little bit about photoelectric sensors – a blessing
Under normal circumstances, a photoelectric sensor consists of two parts: a processing path and a processing element. Its basic principle is to use the photoelectric effect to convert the measured change into a change in the optical signal, and then use the optoelectronic components to further convert the non-electrical signal into an electrical signal. The "photoelectric effect" refers to the use of light ...
