Abstract
1295144 Piezo-electric pressure transducers LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT 24 July 1970 36107/70 Heading G1N [Also in Division H4] A pressure transducer comprises a piezoelectric element 3 Fig. 1 mounted on an elastic diaphragm 2 forming the cap of housing 1 incorporating a transistor 5. The energising voltage is fed by a coaxial cable 7 through an external load resistor and the voltage across the resistor constitutes the signal voltage.
