While replacing or picking a new pressure device, we have to keep several types of process connections in mind. When the technical documentation gets particularly dense, we might even find yourself asking, what is a coplanar pressure transmitter?

What does a pressure device do?

In general, pressure devices can measure pressure, level, and flow. But when we decide to measure level and flow, we shall need to couple the device to another element, such as a pitot, orifice plate, or a wet or dry leg.

For this, we can find three ways to connect the device to the element: in-line, coplanar, and biplanar mounts. All these options have pros and cons, so we need to decide which of the ones provides the most benefits to our process that we are using.

A coplanar pressure transmitter mount has two process connections on the bottom of the transmitter, and we usually use it for differential pressure devices. But it can measure absolute and gauge pressure, and it’s fairly light too.

Last but not least, the biplanar mount, our traditional option like IEC 61518. It installs on the side of a transmitter for differential, gauge, or absolute pressure. Usually, this connection weighs more than the others and is more difficult to install. But no worries, the device will be installed without needing special support or an extra hand. 

Companies using coplanar pressure transmitter technology will usually tout its reduced weight, direct mounting, and other advantages. But it’s up to us whether we want to try this style.

We offer both options either coplanar and traditional for the manifold as well as the pressure transmitter. To know more about coplanar pressure transmitter, you can get in touch with our engineers!
