SIWAREX WL230 SB-S SA
The shear beam load cell is particularly suitable for implementation in container, overhead rail conveyor and platform scales.
The measuring element is a shear tension spring made of stainless steel to which strain gauges are applied. The strain gauges are arranged at 45°to the longitudinal axis on the side of the spring body and are therefore subject to shear forces. Under the influence of the load acting in the measuring direction, the spring bodies and therefore the friction-locked strain gauges are elastically deformed. This generates a measuring signal voltage that is proportional to the load.
