Air pressure regulator with flow sensor

A combination air regulator and sensor assembly comprising:

• a head including a first chamber having an inlet and an outlet,
• a regulator dome including a second chamber linked with the first chamber through a bore, the second chamber including at least one outlet;
• a valve assembly housed within the bore and moveable between closed and open positions sealing and allowing flow in the bore;
• a first diaphragm positioned in the second chamber and linked with the valve assembly, the valve assembly moving in response to a pressure applied to the first diaphragm;
• a spring contacting the first diaphragm and applying a biasing force to the first diaphragm;
• a sensor dome including a third chamber linked with the outlet of the second chamber, the sensor chamber including a discharge outlet,
• a second diaphragm positioned in the sensor chamber, the second diaphragm including a hole formed there through allowing passage of air between opposing sides of the second diaphragm;
• electrical contacts attached to the sensor chamber, the electrical contacts selectively engaging a component of the second diaphragm responsive to a differential pressure of the second diaphragm to define an electrical switch.

• a second diaphragm positioned in the sensor chamber, the second diaphragm including a rubber disk having a conductive contact ring attached on one side of the rubber disk and a non-conductive cup washer attached on the same side of the disk, the cup washer including a hole formed there through allowing passage of air between opposing sides of the second diaphragm;
• electrical contacts attached to the sensor chamber, the electrical contacts selectively engaging the contact ring and responsive to a differential pressure of the second diaphragm to define an electrical switch.
