LOW PRESSURE SIGNAL SENSOR AMPLIFIER AND ANALOG COMPUTER USING THE IMPACT MODULATOR AS THE BASIC ACTIVE PURE FLUID DEVICE. PART II. LOW PRESSURE SIGNAL SENSOR AMPLIFIER.

Abstract

The purpose of the investigation was to design an amplifier capable of sensing the output of a vortex rate sensor. The differential output of this rate sensor has two serious limitations; first the differential output change is small per degree of rate change, and second the sensor has a very high output impedance. An amplifier was constructed and bench tested with the sensor where feasibility was shown. The amplifier had high input impedance and sufficient gain but due to the small signal changes, the signal to noise ratio was poor. This work did point out the importance of proper impedance matching in fluidic devices, and suggested a new design concept for the amplifier. (Author)
