Our differential pressure transmitters feature Yokogawa DPharp technology to deliver accurate, repeatable, and fast-responding differential pressure measurements. Traditional mount or remote diaphragm seal mount configurations are available.
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.
Diaphragm Seal System consists of differential pressure or gauge pressure transmitter with one or two diaphragm seal.
Direct Mounted Diaphragm Seal System consists of differential pressure transmitter with single direct mount diaphragm seal.

Differential pressure level measurement has an enemy- temperature. Temperature can have a negative effect on the accuracy of level measurement. This article covers why temperature has this effect and how it can be reduced.
