We often see weighing instruments in stores and supermarkets. These are electronic scales. For those who often contact with these, when we mentionThe weighing sensorI think they are familiar with weighing modules. They have been applied in many fields. Some people have a vague understanding of the weighing sensor and weighing module, and often regard them as the same thing. What is the difference between the load cell and the load module? Next, I will show you the difference between the weighing sensor and the weighing module.
Difference 1: The load cell only measures the weight and only the direction of the gravity field. The weight will always be greater than 0. If a container is placed under the load cell, it will not produce weight in the opposite direction. Different force sensors can measure positive direction, negative direction, tension and pressure.
Difference 2: The load cell is produced in the factory and then calibrated on site. The weighing sensor shall be calibrated in the factory immediately after production to ensure that the measured value of the sensor is the same after disassembly and installation. Therefore, the structure of the weighing module and load cell is stronger than that of the load cell to ensure the repeatability of the measured value under changing conditions.
Difference 3: Sometimes the weighing module and the weighing sensor have different standards. The weighing sensor is generally the trade scale standard. The weighing module needs to meet the requirements of VDI2635 or ISO376 standards. Repeatability is an important factor in these standards.
The above content introduces the difference between the two, and I believe you will understand it after reading it. Of course, it is not only applied to industrial automatic control, parameter measurement of working environment and working medium, but also combines sensor technology with computer technology to form micro multi-function and intelligent sensors, making it easier to popularize and develop the state control of mobile mechanical equipment. Therefore, load cell technology is widely used in automobiles, construction machinery and other equipment to improve the technical performance of these equipment.
