<p>A simplyfied method and apparatus for electronic pressure control with compensation for current operating temperature and pressures in which computer memory is employed for storing a plurality of firmware models which characterize the effects of temperature and pressure variations on (1) fluid flow through the flow restrictor (15a, 15b, 15c), (2) the temperature sensor (219), and (3) the pressure sensor (16a, 16b, 16c), so that control signals can be generated which compensate a plurality of thermally coupled sensors for changes in current operating temperatures and pressures. <IMAGE></p> |
