- DP cell
-
A DP cell is a device that measures the differential pressure between two inputs.[1]
Example:
You have a pressure container where you connect the H-side (high) of the DP-cell. The L-side (low) you leave in the atmosphere (open air). The DP-cell will tell you the pressure in the pressure container relative to atmosphere pressure. Depending on what class the DP-cell is, it will give you feedback with a current signal. Normal in Europe is 4-20 mA,[2] where 4 is lowest and 20 is highest.
