Compression Column Load Cells
Description
The symmetrically constructed compression column load cells are used to measure compressive forces in a wide variety of industrial applications. They are very compact and deliver extremely precise and reproducible measurement results, even in long-term use in harsh industrial environments.
This compressive load cell is particularly suitable for use in container, bunker and vehicle scales. Four square pillars on which strain gauges (DMS) are positively attached serve as the measuring element. Due to this special "four-column construction", the load cells are generally insensitive to eccentric loads. The applied load causes elastic deformation of the columns. The applied strain gauges deliver a measuring voltage proportional to the load. The compression load cell is calibratable according to OIML, R60. It is made of high-quality, stainless steel, laser-welded and meets the requirements of protection class IP68.
