Product Review: Schneider-Foxboro IAP10

Today, we’ll review the IAP10 from Foxboro, a company of Schneider Electric. Once a big player in the instrumentation world, Foxboro has a good reputation on the market. Let’s see if it holds up.

We’ll check out the IAP10 absolute pressure transmitter but also comment a bit on the gauge version, the IGP10. Ready? Come on then!

Whatcha got there?

You’ve heard of Foxboro before, right? Pretty good rep, bought by Schneider Electric a few years back. Its devices have stayed simple and efficient, which is okay for the brand. But with devices from other big players sporting shiny new tech, Schneiboro needs to beef up soon.

Finding the deets for the IAP10 on the website took more work than I expected. Even though the site looks new, it has a mediocre user experience.

As for the device itself, the first impression you get is that of a robust device with a dated design. It has an optional local display, just a two-line indicator showing the process measurement and the unit. If you have to set up the IAP10 in the field, you have two push buttons to navigate the device menu, so it’ll take a minute or two.

Furthermore, you need to open the cover to access the buttons. Or you can get an optional external zero push button if you don’t want to open the cover. Better than nothing, right? Eh. A handheld will make setup easier than this local screen.

The Foxder website says you can apply the IAP10 in segments such as chemical, oil and gas, food and beverage, and others. A device that claims this much flexibility needs multiple protocols, and the IAP10 rises to the occasion. It has analog, HART, FoxCom™, and FOUNDATION Fieldbus protocols. No PROFIBUS PA, though. Yes, that always bugs me.

What can it do?

It can measure absolute pressure in different parts of your process. The IAP10 has a broad measuring range and decent accuracy as well.

For instance, you can choose a span limit from 1 to 30 pounds per square inch (psi), 10 to 300, or 100 to 3000. The gauge version, the IGP10, has two additional options for hygienic processes, 3.5 to 200 millimeters in water (mmH2O), 100 to 600 psi, and 2000 to 6000 psi for standard applications. The hygienic version comes with different documentation, so you’ll need to find that for your specs.

The tech docs for hygienic devices have the reference accuracy as +-0.20 percent of span. You also get the equation to calculate the span accuracy for sensors B, C, D, and E. The standard reference accuracy comes in at +-0.05 percent, and you can find equations to calculate the square root output, calibration frequency, and that other stuff.

The IAP10’s tech doc has a table with the process temps it can support. For instance, with the display, the device can work from -29 to +85 degrees Celsius, and without from -40 to 85 degrees Celsius.  The process connection limits will depend on the fill fluid, too. For example, silicone has a standard operating temp from -29 to 82 degrees Celsius and operative limits from -46 to 121 degrees Celsius.

Why should I care?

Well, the IAP10 can work in harsh, hazardous or sanitary environments, given the right housing materials and process connections. For housing, you can choose aluminum or stainless steel 316L for the standard and hygienic version. For process connections, you get choices like Tri-Clamp, NPT external, and others. And you have approvals and certifications such as flameproofing, explosion proofing, ATEX, IECEX, INMETRO, and others.

Once again, if you want advanced features, keep searching. The IAP10 has the necessary data and diagnostics through the digital protocols, but that’s it.

In general, the IAP10 is a good device you can deploy in different applications. The IAP10 handles absolute pressure and the IGP10 handles gauge, but other than that, they’re similar. Scale one out and do your research to find out how the device will suit your needs.
