摘要： A hand-held digital tire pressure gauge is designed such that it will provide valid tire pressure readings even for tires that have an elevated temperature due to the vehicle having been recently driven. The measurement from an ambient (outside) air temperature sensor is subtracted from the measurement of a sensor that employs a unique device for sampling inner tire air temperature and the result is then multiplied by a known factor representing the normal unit of air pressure variance experienced per unit of temperature variance. This value is then subtracted from the measurement of a tire air pressure gauge sensor to derive and display a “corrected” air pressure that the tire would have had if its inner air temperature were equal to the surrounding air temperature. The objective of the gauge is to help the user to realize increased fuel mileage, reduced tire wear, and improved handling and safety of the vehicle.
