Abstract

This paper describes the design and development of a primary system prototype based on the diving bell manometer, for the calibration of low range differential pressure gauges. Construction of the instrument is discussed, and a basic dimensional characterization is accomplished. With this prototype a digital differential sensor calibration is performed, and then compared these results with those obtained by the Spanish National Metrology Institute (CEM) for the same instrument.
