System to control pressure in a test device |
摘要 |
Embodiments of the present invention are directed toward pressure controllers and calibrators for setting or measuring pressures in test devices. In one embodiment, the pressure controller contains a dual reference pressure controller. The dual reference pressure controller is operable to maintain two different pressures relative to a reference pressure. The first pressure being a relatively fixed amount greater than the reference pressure and the second pressure being a relatively fixed amount less than the reference pressure.
