The bending ring load cell is particularly suitable for implementation in container, conveyor, platform and roller table scales.

The measuring element is a bending ring made of stainless steel. Two expansion measuring spirals are applied each to the upper and lower faces of the ring. Under the influence of the centrally acting load in the measuring direction, the bending ring is tilted, i.e. the diameter of the upper ring face is reduced and the diameter of the lower ring face is increased. This causes the bending ring (and the expansion measuring spirals installed with friction-locking) to be elastically deformed. This generates a measuring signal voltage that is proportional to the load.

Load cells with a rated load of up to 13 t are equipped with integral overload protection.
