Abstract
The present invention relates to a temperature-compensated pressure sensor assembly for fitting within the valve stem of a vehicle tire. The assembly includes a substrate assembly defining a plurality of holes. A pressure sensor is mounted to the substrate assembly. The pressure sensor includes a first deflectable membrane defining a first chamber and a first cap mounted to the membrane to form a second chamber. A temperature compensation sensor is mounted to the substrate assembly. The temperature compensation sensor includes a second deflectable membrane mounted to the substrate assembly to define a third chamber and a second cap mounted to the other membrane to form a fourth chamber.
