Differential Pressure

Differential Pressure (DP) transmitters measure the difference between two pressures. They use a reference point called the low-side pressure and compare it to the high-side pressure. Ports in the instrument are marked high-side and low-side. The DP reading can be either negative or positive depending on whether the low-side or high-side is the larger value. A DP transmitter can be used as a gauge pressure transmitter if the low-side is left open to the atmosphere.

Example Industrial Applications: Closed Tank Level, Density, Filter health, and DP Flow (Secondary Element)

Yokogawa gauge pressure transmitters use digital DPharp sensor technology to get accurate, reliable readings to you quickly.
