Pressure testing device for vehicle tire, comprises pressure sensor which detects tire pressure and generates signal corresponding to tire pressure

摘要

The pressure testing device (10) comprises a pressure sensor (12) which detects tire pressure and generates a signal corresponding to the tire pressure. An air valve seat (14) is manufactured from and electrically conducting material and is electrically connected with the pressure sensor. The flap (161) of the transmitter antenna (16) is a metallic material and is connected with air valve seat. A ring shape substrate which defines a central coupling hole is coupled to the flap.
