What are the materials of the load cell?
What is a load cell, which is a kind of detection device composed of one or more forces that are deformed after the force, so what is its composition? And listen to the force sensor manufacturer 's small series for your detailed analysis:
In the initial production of load cells, special silicone rubber sealant series were used, because this material has the characteristics of anti-corrosion, anti-aging, moisture-proof and insulation.
Generally, the elastomers are made of metal materials such as aluminum alloy, alloy steel, stainless steel, etc., because they have rigidity, can maintain deformation and deformation recovery, and have good corrosion resistance.
Patch adhesive material
Using two-component polymer epoxy series adhesives, the properties of polymer chemical products are closely related to the physical and chemical indexes of each component, such as purity, molecular chain structure and size, storage time, composition ratio, Molecular modification, mixing method, mixing and curing time, curing time, curing temperature, additives and percentage.
The wire is also generally made of metal material, in which the silver plating wire is certainly better than the copper wire, and the copper wire is better than the aluminum wire, which is also a factor affecting the quality difference.
Strain gauge and resistive component materials
The combination of the strain gauge substrate and the strained copper is ever-changing. According to its strain requirements, there are currently nearly a thousand products. Generally, the substrate is made of a polymer film material, and the strain material is high-purity constantan. The Constantan on the substrate is optically treated to etch different resistance-deformed resistance wires. Therefore, the quality of the strain gauge is not only related to the material quality of the substrate and the purity of the composite metal, but also related to the composite process, etching technology and process, etching chemical materials and post-treatment processes and materials.
