A load cell is a sensor device that measures the force of an object by checking the load on the load carrier. The Load Cell can convert the pressure from the carrier into a corresponding electrical signal to achieve the purpose of measurement. The load cell is the mass A device that converts a signal into a measurable electrical output.
Before installing the load cell, you should first consider the actual working environment of the load cell, which is very important for choosing the correct installation of the load cell. The use environment of the load cell is related to the normal operation, service life and reliability of the load cell Related to safety, the load cell is divided into 8 types according to the conversion method: photoelectric, hydraulic, electromagnetic, capacitive, magnetic pole change form, vibration type, gyroscope, resistance strain type, etc.
There are differences in quality between the technical indicators of load cells and national standards in basic concepts and evaluation methods, such as S-type load cells, cantilever type load cells, Column Type Load Cell, spoke type load cells, plate rings Type Load Cells, Bellows Type Load Cells, Bridge Load Cells, etc.
The working principle of the load cell is to stretch and thin the metal resistance wire under tension, and then the resistance increases, that is, the metal resistance changes with the strain it bears. The load cell is used to convert the weight signal or pressure signal into electricity The signal conversion device, the construction principle of the load cell is that the metal resistance has the characteristic of hindering the flow of current.
