Product Review: Rosemount™ Wireless Pressure Gauge

Yo, you ready for another product review? Yeah you are, don’t front. Oh look, more Emerson! Somebody act surprised! Hey, it’s not my fault Emerson has outstanding devices and solutions that deserve mention.

This April we’re journeying through the pressure world, covering everything related to pressure measurement. I got an idea this week to talk about a product with an old concept that got an upgrade to make it useful again.

So let’s say hi to the Rosemount Wireless Pressure Gauge! Good thing the device is better than its name. It starts off like a traditional manometer, but this gauge brings a lot of new features for your application. Where can you use it? Let’s dive into the details to find out. You know how things work here, right?

Take a seat, grab a BRLO beer from Berlin, have a read, and draw your conclusions!

Whatcha got there?

A strong yet cheap option for all kinds of pressure measurement! This gauge is a flexible device that can fit right into your plant and start improving reliability immediately.

The first time you see it, you don’t expect to find fancy features. It has a traditional indicator rather than a digital LCD to process information. However, it does have discrete LEDs to show specific data to the technical-type people. At this point, the operators don’t need to worry about these diagnostics.

And why should you have a wireless pressure gauge? Because it lets you keep a traditional indicator by connecting through your wirelessHART protocol. Furthermore, it makes monitoring energy, pressure, and performance cheaper. Hard to beat that.

It installs as easily as a traditional manometer, so you’ll get more data externally. Plus you have a good list of wetted part materials which covers just about any process you might have.

What can it do?

It provides options for pressure applications like gauge, absolute, compound, and vacuum. It also gives you a measurement range up to 4000 psi and acceptable accuracy up to 0.5 percent of the span.

While it doesn’t have special features, it does bring benefits. It reduces maintenance and safety issues by allowing you to read all data remotely. Wouldn’t you rather check your process variables in the control room instead of going out to the field?

It also has several standards for process connections and a list of approvals for various processes. Last but not least, you have two engineering units on the face of the gauge with the most common units for applications.

Why should I care?

Do you want a low-cost application? Then consider this gauge. The real highlight here is the wirelessHART communication. You can easily add wireless to your plant, with no extra structure, while keeping operators happy with their local visualizations.

The update time of the transmitter ranges from 1 to 60 minutes, and the estimated battery life goes up to 10 years. Unfortunately, Emerson’s power lifetime estimator doesn’t have this model yet to check the lifetime against your own process specs.

The company launched a new video about a case at Unilever in Costa Rica. Here you see the Rosemount Wireless Pressure Gauge monitoring pressure and controlling the process. It also shows how the gauge depicts pressure in different colors to improve readability. And it has remote monitoring and the local indicator to increase reliability.
