    Outflow and pressure relief valve on a Boeing 737-800. Airflow into the fuselage is approximately constant, and pressure is maintained by varying the opening of the out-flow valve (OFV). Most modern jetliners have a single OFV located near the bottom aft end of the fuselage, although some larger aircraft like the Boeing 747 and 777 have two.

    direct TPM sensor fitted in valve system, manufacturer VDO. In most current designs of direct TPMS, a small electronic assembly which is rugged enough to be mounted inside a tire, measures the pressure using a microelectromechanical system (MEMS) [1] pressure sensor and then transmits this and other information to one or more vehicle receivers. [1]
