What is differential pressure?

What is differential pressure?

Differential pressure is is the pressure difference (or pressure difference)

and Pressure (Pressure) Vertically acts on the distribution force per unit area.

For an example as below :

A pool with a depth of 20 meters asks how much pressure or pressure is on the bottom 

of the pool? Anyone who has studied physics knows that 20 meters of water can produce 2 kg / cm

 of pressure (or pressure)  . That is easy to understand about idfferential pressure and there 're many 

industry field is related with it .and also have some products  . such as pressure transmitter and pressure 

sensor , pressure valve  ... etc .

By the way , have any query about  pressure transmitterand DP transmitter  , temperature transmitter
