  • Pressure sensor housing
    Patent number: 6016102
    Abstract: An apparatus (10) allows atmospheric pressure into an environmentally sealed enclosure for creating an equilibrium that allows a sensor (28) make a proper measurement. A slot or opening (26) in the cover (14) exposes outside atmospheric air to a restricted portion of a gas permeable membrane (18). The membrane (18) allows a selected gas to pass through the membrane (18) creating the equilibrium in the housing (12). A gasket (16) positioned between the cover (14) and housing (12) seals the housing in an air tight manner except for the gases allowed in through the membrane (18). Pressure sensor (28) can then make a more accurate measurement. Apparatus (10) finds particular utility in a low pressure tire management system.
