Apparatus for monitoring tire pressure

An apparatus for monitoring a tire pressurization state in a tire, the apparatus comprising:

• a magneto-mechanical pressure sensor having a linear motion mechanical sensing component, a magnetically hard element and a magnetostrictive element, and a member in said magneto-mechanical pressure sensor, wherein said member toggles at a predetermined pressure differential from a first position to a second position, wherein said member allows said magnetostrictive element to move relative to said magnetically hard element at said first position, and said member changes a characteristic resonance of at least one of said magnetostrictive element and said magnetically hard element at a second position by a manner being selected from the group consisting of touching and preventing said magnetostrictive element from resonating relative to said magnetically hard element, changing a proximity of said magnetostrictive element relative to said magnetically hard element, changing a proximity of said magnetically hard element relative to said magnetostrictive element, dampening a vibration of said magnetically hard element, dampening a vibration of said magnetostrictive element, and any combinations thereof;
• an electromagnetic excitation system for interrogating said magneto-mechanical pressure sensor;
• a receiver for receiving information from said electro magnetic excitation system;
• and
• a data interpretation system for translating said received information into the tire pressurization state, said data interpretation system being connected to a display to communicate the tire pressurization state to an operator.
