Abstract
The elements of a tire pressure monitoring and transmitting system are encapsulated into a single package. A pressure sensitive device is covered with a flexible gel coat and then inserted into a molding tool cavity. A removable pin is incorporated into the molding tool and in its normal position is in contact with the gel. A molding compound is injected into the cavity so as to encapsulate the device and gel coat. When the pin is extracted and the device ejected from the molding cavity, an airway is left defined by the removable pin. The airway exposes the flexible gel covering the pressure sensitive device to the local air pressure, whereby the gel, being flexible, transfers the pressure to the pressure sensitive device.
