An algorithm for fast regulation of dynamically generated pressures in the range 1 Pa–7 kPa

An innovative regulation algorithm that allows to stabilise quickly the pressure in the range 1 Pa–7 kPa in a leaky chamber using a commercially available pressure regulator designed for atmospheric pressure range has been developed. The algorithm has been implemented on a nonrotating digital piston gauge allowing automatic calibration of pressure sensors. This algorithm could be used helpfully to generate starting pressures for dynamic expansion systems.
