Abstract:
A force transducer, in particular a load cell, includes a spring body that deforms when loaded with a force or load to be measured. Two support parts, which are separated by a gap, are moved out of a position of rest. A capacitive displacement detector is used to detect the relative movement of the support parts, where the capacitor includes two electrode combs that are each held on one of the support parts and includes a multiplicity of electrode fingers. The electrode combs are configured designed and mounted on the two support parts such that the electrode fingers of the one electrode comb pass into the finger interspaces of the other electrode comb when the spring body is loaded so that the force transducer is resistant to overloading.
