Abstract
This invention is a multiple channel high data rate pressure sensing device for use in wind tunnels, spacecraft, airborne, process control, automotive, etc., pressure measurements. This device offers data rates in excess of 100,000 measurements per second with inaccuracies from temperature shifts less than 0.25% (nominal) of full scale over a temperature span of 55.degree. C. This device consists of thirty-two solid state sensors 11, signal multiplexing electronics to electronically address each sensor, and ditital electronic circuitry to automatically correct the inherent thermal shift errors of the pressure sensors and their associated electronics.
