Packaging for RF signal sensor with battery changing capabilities and method of using
First Claim
1. A pressure transducer assembly mountable in an interior of a tire for sensing a pressure of a fluid in said tire comprising:
- a sensor housing having a first compartment in fluid communication with said fluid;
a second compartment separated from said first compartment by a divider slideably engaged with and removable from said sensor housing;
said divider having disposed thereon a circuitry;
said circuitry including a pressure transducer in fluid communication with said first compartment, and a transmission circuit coupled to said pressure transducer for transmitting a signal responsive to said pressure to a remote location;
a removable power source coupled to said circuitry contained entirely within said second compartment; and
a cover sealing engaged with said housing and said divider such that said second compartment is not in fluid communication with said first compartment.

Abstract
A pressure transducer assembly mountable in an interior of a tire for sensing a pressure of a fluid in the tire comprising: a sensor housing having a first compartment in fluid communication with the fluid; a second compartment separated from the first compartment by a divider slideably engaged with and removable from the sensor housing; the divider having disposed thereon a circuitry; the circuitry including a pressure transducer in fluid communication with the first compartment, and a transmission circuit coupled to the pressure transducer for transmitting a signal responsive to the internal pressure to a remote location; a removable power source coupled to the circuitry contained entirely within the second compartment; and a cover sealingly engaged with the housing and the divider such that the second compartment is not in fluid communication with the first compartment. A method of sensing the tire pressure and communicating a signal responsive to the tire pressure to an external receiver located in a remote location is also disclosed.
