FREQUENCY OUTPUT PRESSURE SENSORS BASED ON AN APPLICATION OF SURFACE ACOUSTIC WAVE TECHNOLOGY

A new type of frequency output pressure sensor is described which utilizes a novel application of Surface Acoustic Wave (SAW) technology. Variations in SAW velocity over a miniature pressure dependent diaphragm are used to control the frequency of an electronic feedback oscillator. Prototype SAW pressure sensors have been built which provide a frequency output that varies almost linearly with applied pressure and is accurate to better than 0.2 percent of full scale.
