Flueric notch filter temperature or density sensor

Flueric notch filter temperature or density sensor

The temperature sensors shown utilize a constant frequency fluidic oscillator to excite resonance tubes, whose frequency response is a function of temperature. The outputs of these sensors control a fluidic amplifier, whose output is rectified and filtered to produce a D.C. fluid signal which is a f...

Beschreibung
Zusammenfassung:The temperature sensors shown utilize a constant frequency fluidic oscillator to excite resonance tubes, whose frequency response is a function of temperature. The outputs of these sensors control a fluidic amplifier, whose output is rectified and filtered to produce a D.C. fluid signal which is a function of the sensed temperature. Different embodiments utilize resonance tubes excited in phase or 180 DEG out of phase to sense the difference between two temperatures or to provide increased sensitivity.
