Our differential pressure transmitters feature Yokogawa DPharp technology to deliver accurate, repeatable, and fast-responding measurements. Traditional mount or remote diaphragm seal mount configurations are available.
What is the Function of a Pressure Transmitter?
Pressure transmitters monitor and communicate the pressure measurements of equipment.
How Does a Differential Pressure Transmitter Work?
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 level transmitter 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.
Digital Differential Pressure Transmitter
As part of a digital transformation, digital differential pressure transmitters can make data-gathering operations more efficient and safe for people.
