• Description : The only difference between tool steel and stainless steel shear beam load cell is the component material used.

Overview

• 　　Why use a real airtight shear beam load cell?

  　　Above we mentioned the sealed shear beam load cell. In the weighing industry, the most commonly used technology is the strain gauge load cell. Strain gauges are very sensitive and need to be protected from moisture, chemicals, and mechanical damage. Many people believe that all load cells made of stainless steel are protected, but this is not the case. In order to obtain the highest level of moisture resistance, the load cell must be stainless steel and sealed. The hermetic seal will ensure the integrity of the strain gauge section of the battery in corrosion or flushing applications.

  　　Choose the right equipment to do the job

  　　The success or failure of any electronic weighing system ultimately depends on choosing the right equipment. An important aspect of choosing the correct shear beam load cell is to ensure that the load cell is properly sealed in the environment in which it is used. If the environment is humid, the humidity is high or the load cell will be washed away, the only option that should be considered is a sealed stainless steel load cell.

  　　The difference is the seal

  　　The only difference between tool steel and stainless steel shear beam load cell is the component material used. The method of sealing these shear beam load cells is the same. Only a truly hermetic sealing process can prevent moisture from entering the load cell. To achieve an environmentally sealed load cell, the cavity where the strain gauge is installed must be potted, and the potted part must be covered with a plate glued in place, and a gasket should be used where the force sensor cable enters the body of the load cell And O-ring. A true airtight load cell covers the measuring chamber with a cover that can be welded in place, and a welded joint for connecting cables. The welded header is the key. Some stainless steel load cells provide welding coverage within the gauge length but do not include welding cable joints.
