Windows 11 vs. Windows 10; MacBook Air vs. iPad Pro; Mobile. However, this pressure changes with the weather and the height above sea level. Gauge/Gage pressure: The pressure above atmospheric is gauge pressure. Silicon-based sensors are usually doped to provide a gauge factor of around 100 to 200, which gives a good compromise between sensitivity and thermal characteristics. As soon as the absolute pressure is lower than the atmospheric pressure, one refers to it as negative gauge pressure.

It damps the moving parts within the case and thus prevents damage and increased wear. This dynamic sensitivity means they are good at measuring small changes in pressure, even in a very high-pressure environment. For example Blood pressure. The output from a silicon sensor can be around 10 mV/V. Static pressure vs. pressure head in fluids. Mathematically, we could say that absolute pressure is always a higher value than gauge pressure, by exactly one atmosphere. Fuel Rail Pressure Sensor Circuit Malfunction.
