The load cell is a device that converts the quality signal into a measurable electrical signal output. When using a sensor, we should first consider the actual working environment of the sensor, which is crucial to the correct selection of the weighing sensor. It is related to the normal operation of the sensor, its safety and service life, and even the reliability and safety of the entire weighing instrument. The load sensor is a sensor device used to measure the force on the object by checking the load on the carrier. The load sensor can convert the pressure from the carrier into the corresponding electrical signal, so as to achieve the purpose of measurement.
With the progress of technology, the electronic scales made of load sensors have been widely used in all walks of life, realizing the rapid and accurate weighing of materials, especially with the emergence of microprocessors and the continuous improvement of the automation of industrial production process, the load sensors have become a necessary device in process control, from the weight measurement of large tanks, hoppers and other weights that could not be weighed before to the crane scales Load sensors have been used for measuring and controlling such as car scales, to the batching system for mixing and distributing various raw materials, automatic detection in production process and control of powder and particle feeding quantity. At present, load sensors have been used in almost all weighing fields.
