ABSTRACT:
A pressure-to-electric output system is used to convert the dual outlet pressure signals of a fluidic angular rate sensor to a pair of oscillating electrical signals whose relative frequency differential is very accurately indicative of the sensor outlet pressure differential. The sensor outlets are fluidically coupled to the control ports of the first amplifier in a cascaded series of fluidic proportional amplifiers. The outlet ports of the terminal amplifier are coupled to the inlet ports of a pair of fluidic oscillators. A pair of microphone type pressure-to-electric transducers are driven by the oscillators to produce the oscillating electrical signals.
