Claims

[Scope of Claim for Utility Model Registration] A pressure sensor for detecting supercharging pressure from a supercharger used in an internal combustion engine of an automobile, and a pressure sensor for detecting supercharging pressure detected by the pressure sensor. In the supercharging pressure display device having a display means for displaying the value to the driver of the vehicle; It consists of a bar graph display means 2 for quantitatively displaying the value of the boost pressure, and also for distinguishing and displaying a preset appropriate boost pressure range N and the boost pressure ranges H and L above and below it. The digital display means 1 and the bar graph display means 2 are provided in parallel to display the value of the supercharging pressure, and in addition, the display means 1 and 2 display the value of the supercharging pressure which changes every moment. Both have a hold means 3 for holding one of the displays for a predetermined time recognizable by the driver and displaying the display over time, and furthermore, a boost pressure exceeding a dangerous value which can be arbitrarily set is detected. It has an alarm means 4 for warning the driver at certain times, and further includes an alarm means 4 for warning the driver, and further includes an alarm means 4 for warning the driver.
A main body part 5 incorporating the holding means 3 and the alarm means 4 can be attached to a position within the automobile 6 that is visible to the driver, while the pressure sensor 7 is separated from the main body part 5. A supercharging pressure display device for a supercharger of an internal combustion engine, characterized in that the supercharging pressure display device is connected electrically.
