Abstract:
A method of calibrating an integrated pressure management apparatus, the method comprising:providing a chamber having an interior volume varying in response to fluid pressure in the chamber, the chamber including a diaphragm displaceable between a first configuration in response to fluid pressure above a certain pressure level and a second configuration in response to fluid pressure below the certain pressure level; providing a resilient element applying a force biasing the diaphragm toward the first configuration, the providing a resilient element includes providing a leaf spring having a first end fixed with respect to the chamber and a second end contiguously engaging the diaphragm; providing a switch actuated by the diaphragm in the second configuration; providing an adjuster contiguously engaging the resilient element, the providing an adjuster including providing a calibrating screw threadably mounted with respect to the chamber; connecting the chamber to a pressure source at the certain pressure level; and adjusting the biasing force such that the switch is actuated at the certain pressure level, the adjusting includes turning the calibrating screw in contiguous engagement with an intermediate portion of the leaf spring between the first and second ends.
