Sensor assembly, for measurement of a physical value, has a Wheatstone bridge with resistances sensitive to membrane distortion and non-sensitive resistances in series with them

摘要

The sensor assembly, for measurement of a physical value, has at least one Wheatstone bridge where at least one bridge resistance has at least one ohmic measurement resistance sensitive to membrane distortion to give an electrical signal for evaluation corresponding to the distortion. A detuning resistance is directly or indirectly parallel to at least one bridge resistance. A resistance (E), not sensitive to distortion, is in series with the distortion-sensitive resistances the bridge.
