Things To Consider Before You Use Compression Load Cells
Weighing machines like tension, beam and single point loads mainly use compression load cells. It is used to measure a machine's pushing and squashing force, and you can find such cells installed at the underneath level of a weighing machine. Tension load cells are also used in these machines to measure the loading strength, but compression load cells are unidimensional and can be used to measure downward compression.
You can find such cells in various industries where compression load cells are used based on shear, bending, ring-torsion or column measurements. But the main working principle of such cells is to measure the capacity of the static weight of a machine such as silos and vehicle scales. Compression cells can also convert the force or weight into an electrical signal, and you can use the strain gauges attached to these cells for the same.
Designs Of Compression Load Cells
Column or canister cells are the most common cells that can be mounted on the surface, and you can find a central code or column inside these load cells. You can encase such cells at an outer sheath for protection and isolation, and you can use hermetical force to fix such cells in a harsh environment. Strain gauges are bonded to the surface of this column, orientated in such a way as to detect the deformations that occur under load.
- You need to use such compression load cells for applications where high-capacity static weighing is required, and you need to align such cells properly during the installation. You can use some mounting hardware to fix such cells on a surface.
- Apart from that, you can use button load cells, a type of compression load cell, for low testing and measuring different applications. You can find such low-capacity cells in a pump mostly used in the oil and gas industry.
- Tension load cells can measure the pulling pressure, and you can use such compression load cells to measure the pulling pressure with a single axis. Such load cells are known as blocks which can hold a load at a point to measure the compression load of a particular structure or machine. Once you apply the load on these cells to measure the compression, you need to remove the strain gauge, known as the deformation process. Through this deformation process, you can measure the pulling pressure.
- You can also measure the resistance capacity of a column by using such cells, and these load cells can detect the relative changes in resistance. For example, bridge circuits are used to measure the resistance capacity, and they can provide accurate results.
How To Choose Compression Load Cells?
Most compression load cells are designed with robust materials that are rust resistant. These cells are not affected by scratches, and you can use such cells to measure the deformity rate of a structure. Along with that, you can find such cells covered with a base plate to ensure the highest standard of stability.
People can use such load cells in a restricted area because customized load cells are available for different applications and can be made according to your specifications. Make sure you check the HBM capacity of a load cell before you choose, as most load cells are available with 30-50 tons of HBM. HBM supply can be determined according to the project that you want to use.
Only a few manufacturers available can provide such load cells, and most of them cannot install such cells in potentially explosive environments. So, if you want to use such load cells in a hazardous area, you must check the specification and installation guidelines offered by the manufacturers.
Closing Thoughts
You can search for such compression load cells online to choose the best one. Make sure HBM capacity, load bearing capacity, installation process, material quality and warranty should be checked before you make a final purchase. It is expensive equipment that can be used for different industrial applications, and you can take help from an expert to choose the best compression load cells.
These are important components of modern industrial, manufacturing, weight-based sales or quality assurance environment. There is a wide array of options available in the market. They are available in different configurations and under different brand names, so make sure that you closely assess the requirements and pick the best one.
