Yes, we’re doing more pressure transmitters! Don’t worry, this one is a little different from the last. Today, let’s have a look at the Cerabar PMP11, a simple and compact gauge pressure transmitter from Endress+Hauser. You know the drill by now, so stick around and we can get started!

What is it?
Like the PMP21 you just read about, the Cerabar PMP11 has a great price and flexible range for your purposes. Virtually a twin to the PMP21, it sports the same design and plug-and-play nature, with no local display or configuration required. It also comes pre-set from the factory, with the capacity for an optional display like the PHX20.
One thing we’ll note about the PHX20: you have to remove the cover to access the tiny navigation buttons and check alarm messages. The display itself isn’t big either, but enough if you need a local display.
What can it do?
You can use the PMP11 to measure gauge pressure for liquids and gases at critical points in tanks and pipes. It measures from 450 mbar up to 40 bar supporting an overpressure to 160 bar, using a piezo-resistive sensor. Our definitive guide to pressure sensors can teach you more about the details.
As for limits, it can work in temperatures from -25 to 85 °C (-13 to 185 °F) and it can install on thread connections like G1/4 and MNPT1/4. It also has a stated reference accuracy of 0.5 percent with a long-term stability of 0.2 percent of its upper range limit per year. Last but not least, it can communicate using analog or volts.
Why should I care?
Like its brother, the Cerabar PMP11 tempts us with an attractive price, flexible features, and easy installation. It also allows the option of a display and local setup, should you decide you need those.
Once again, any problem presented by the device will call for replacement rather than repair. And you have two ways to integrate it into your system and multiple connections for installation.
Should you choose to buy the Cerabar PMP11, you’ll get a simple, low-cost gauge transmitter and little else. Of course, you may need little else. To know more about gauge transmitters, you can get in touch with our engineers and we will be happy to help.
