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.

[ What is claimed is:] [1.] A solenoid pressure transducer for measuring and controlling pressure within a system comprising:a solenoid sleeve of a nonmagnetic material enclosing a pressure chamber, the pressure chamber being in communication with a source of the system pressure;a sensing element comprising a silicon die attached to the sleeve for measuring strain in the sleeve caused by the system pressure;a vitreous glass bond attaching the silicon die to the sleeve; andan actuator with in the solenoid sleeve for controlling the system pressure in response to a pressure measured by the sensing element.
