Abstract
A bourdon tube transducer has included a bourdon tube with a conductive plate electrically separated from the bourdon tube and in parallel with the bourdon tube. As the pressure varies, so does the electrical reactance between the bourdon tube and the conductive plate and this variation is used to vary the frequency of an electrical oscillator that is connected to the bourdon tube and the conductive plate.
