China absolute pressure sensor, gauge pressure sensor

Absolute pressure sensor: absolute pressure means the total pressure on the surface area of an object. Its zero point is based on absolute vacuum, we can call it total pressure

 p321

Gauge pressure sensor: Gauge pressure= total pressure- one atmospheric pressure. Its zero point is the local atmospheric pressure as the reference point.

The difference between them only the zero point.

 P22

For example, in your local atmospheric environment, the gauge pressure sensor shows pressure by zero, but the absolute pressure sensor shows 100Kpa=1Bar= one atmospheric pressure
