This portfolio details the design, construction and testing of three high accuracy digital pressure indicators. A discussion of old and contemporary pressure measurement technologies is included, as well as a comprehensive market survey of electronic pressure measurement instruments currently available. An integrated design strategy is adopted for the three separate digital pressure instruments, namely a battery - powered stand alone unit, a retransmitting version and an intrinsically safe version of the battery powered unit. Their implementation takes into account many design issues including ease of manufacturing, low power circuit design and electromagnetic compatibility. Novel features available upon all three instruments resulting from the design strategy adopted are high accuracy measurements, typically ±0.2% of full scale, a battery life of over 12 months, push button zeroing and linearisation, electromagnetic compliance with minimum design changes and an intrinsically safe power supply design that may be used not only in the instrument for which it was designed but for future instruments. Individual design issues with respect to each instrument are in the three project sections which complete this portfolio.
