How to choose a pressure sensor

When selecting a pressure sensor, keep these five criteria in mind:

1.    Application and measurement type. Common type of pressure measurement include: Absolute, gauge, differential, vacuum, bidirectional, and sealed gage. 

2.    Pressure range. kPa, Bar,Psi, Mpa

3.    Process media. Water, Oil, Gas etc 

4.    Temperature range and installation environment. -30~80℃ etc.

5.    Accuracy. ±0.25%F.S. 

6.    Output. 4~20mA, mV, 0.5~4.5Vdc etc
