These two sensors measure the total pressure on a system. When the single port is left open, then the sensor measures the atmospheric pressure. However, when the sensor is connected to a sealed system, then it adds the system's pressure effect (negative or positive) to the atmospheric value. LOG3090 can also be used an an altimeter.
Applications include:
- Atmospheric pressure measurements
- Altimeter
- Vapour pressure of liquids
- Gas Laws
