ABSTRACT:
A multipoint measuring device is based on a measuring bridge network and uses transducers which convert the quantity under measurement into an electrical signal, the transducers being divided into two identical groups, and being connected via a selector switch and main and auxiliary compensators in one or two adjacent arms of the measuring bridge network. With the transducers connected in two adjacent arms of the measuring bridge network, each transducer group is connected only in a single arm via its respective main compensator and its respective auxiliary compensator and the connection point of two auxiliary compensators is used as a measurement point of a measuring diagonal of the measuring bridge network. With the transducers connected in a single arm of the measuring bridge network, each transducer group is connected alternately in a respective arm via its respective main compensator and its respective auxiliary compensator, while only a respective auxiliary compensator is connected to the measurement point of the measuring diagonal of the measuring bridge network.
