SIEMENS SIWAREX WL270 CP-S SA
The compression load cell is particularly suitable for implementation in container, hopper and vehicle scales.
The measuring element is a solid cylinder made of stainless steel to which 4 strain gauges are applied.
The load which acts centrally in the measuring direction causes the spring bodies and therefore the friction locked strain gauges to be elastically deformed. This generates a measuring signal voltage that is proportional to the load.
