Work criteria
Like all other modern load cells, column load cells are essentially transducers that convert force or weight into electrical signals. They did this by connecting a strain gauge to the body of the load cell. Under compressive load, the body of the load cell will deform slightly. This is detected by the strain gauge, which deforms in accordance with the body, which causes the voltage to change. This voltage signal is proportional to the initial force or weight, so it can be used to calculate it.
design
Classic examples of compression load cells are cylindrical or tank load cells. These are usually cylindrical devices with mounting surfaces on the top and bottom ends. Inside there is a central core or column as a load-bearing element. The strain gauge is bonded to the surface of the cylinder, and its direction should be able to detect the deformation that occurs under the load. Usually, the single-point load cell is wrapped in an outer sheath to protect the internal components and isolate them from the environment. Many sealing devices can be used in harsh or dangerous environments.
These load cells are reliable and accurate solutions for applications involving large-capacity static weighing. It is important to align the battery correctly during installation to ensure accurate readings. Usually, this is achieved by coupling them with specially designed mounting hardware.
Other common designs for compression load cells include compact, low-profile push-button load cells, which are commonly used in test and measurement applications. In addition, the through-hole or ring-shaped load cell has a center hole, so the device can pass through. An example of this application is in pump monitoring systems in the oil and gas industry.
