Abstract
A solenoid pressure transducer for measuring and controlling pressure within a system includes pressure sensing technology incorporated into a solenoid valve such that a common pressure chamber is used to sense pressure of a fluid and to control the flow of the same fluid. A solenoid sleeve forms the pressure chamber and a sensing element attached to the sleeve is used to measure pressure within the sleeve. The pressure measurement is then used by the solenoid sleeve to control the position of the solenoid valve.
