CAVITY DIFFERENTIAL-ABSOLUTE-PRESSURE TRANSDUCER WITH FREQUENCY OUTPUT

A new construction of the differential resonator microwave transducer is considered, having a number of advantages over other transducers: h igh sensitivity, protection against interference, simple construction, high mechanical strength, etc, The very simple electrical measuring c ircuit gives, without amplification, a frequency output signal of suff iciently large amplitude. The differential principle makes it possible to exclude a number of errors associated with temperature, vibro-shoc k loading, etc., playing a large role in absolute pressure transducers used in flying equipment, working in challenging climatic conditions and under severe vibro-shock loading.
