Unboxing

The CPG1500 fresh from the box has a cool display and easy configuration. WIKA’s choices of new tech on an old idea make a great first impression. It uses an internal battery, meaning you don’t need extra structure to power the device in the field. On the downside, you won’t like the battery life, but we’ll tackle that later.

The device offers an easy setup through the display. Better yet, it also lets you set up through an app on your smartphone or laptop. Sweeeeet.

In the other corner, the Rosemount gauge doesn’t look like anything special at first glance. However, the device has a lot of built-in tech to send data straight to the control room.

Although the device has no digital display, it has a traditional indicator with two scales for visualization. It also offers standard wireless communication so you can integrate the device into the control system.

Display

The CPG1500’s display gives you not only data on your process but also a guide for your setup. The display has 5 1/2 digits and a large matrix area, bar graphs for range visualization, and an adjustable backlight. But wait, there’s more! The display will show you your battery level, Bluetooth activation, and alerts on potential problems with the device.

Instead of a digital display, the Rosemount gauge has a local indicator with two scales, as mentioned earlier. This is okay, because operators know how to use these indicators. It provides simple process diagnostics in three different colors and has a LED to show the battery status. Furthermore, it will warn you if  you have no power or if the device has a problem.

Sensor and performance

The CPG1500 has a wide measurement range, so you can find one to fit your needs. You can choose from three types of sensor – gauge, absolute, and vacuum pressure, and all have different ranges for different applications. For example, the gauge sensor can go from 0 to 250 bar, or from 0 to 700 bar. The other options have the same flexibility, giving you more possibilities, even up to 1000 bar.

Now we need to talk accuracy. The CPG1500 offers up to 0.05 percent – not the best, but enough for most applications in various industries. Too bad I only found one option in the documents for wetted parts, stainless steel 316. You can check for yourself, if you think I missed the others. On the positive side, it comes with several process connections, making installation potentially easier.

The Rosemount also offers a bunch of ranges for gauge, absolute, compound, and vacuum pressure sensors. You can scale out the best for your application without any problem. Sadly, the max range only goes to 275 bars, way less than the CPG1500.

On the other hand, the Emerson device offers two types of wetted material, giving you a little bit more flexibility than CPG1500. You also have a handful of process connections and approvals for different applications. Not bad.

Integration and battery

The CPG1500 won’t integrate directly into your control system, but the built-in Bluetooth will help with setup and datalogger stuff. You can use the myWIKA app on your phone or WIKA-CAL software on your laptop. You don’t need network structure to communicate with the device, but if you want to send field data to your control system, keep looking. The digital functions only cover local visualization and punctual verification, where you need to know the process trend for a few days.

Next up, battery. Brace yourself: WIKA’s device only offers 2000 to 2500 hours, a drop in the bucket compared to other brands. Here’s the twist. It uses AA alkaline batteries. Yes indeed, the same you find at the supermarket near your house! When you do the math, you may find it cheaper than the fancy long-life batteries everybody else uses.

You can integrate the Rosemount gauge using WirelessHART, one of today’s standard protocols. On the negative side, if you don’t have a wirelessHART network, you need to buy a gateway and other structural bits to gear up properly. Once you have those, you can connect to the control system easily, then access setup, diagnostics, and such remotely.

The battery sounds better on this one. You can get up to 10 years here, depending on how you set your update time, as it ranges from 1 minute to 60. However, you won’t find this device on Emerson’s online power estimator. Emerson needs to get on that.

Information and documentation

To put it bluntly, WIKA needs a more user- and mobile-friendly site. Finding information is hard, and the site has no mobile version, making  life a little more complicated. The technical documents generally pass muster, and you can search them with few problems. It also has a good blog you should check out.

Emerson has a superior website, easy to navigate and find what you need. Plus it has a mobile version, making things more convenient. Better still, it has blogs and microsites with plenty of dedicated data about the products, and the tech docs are clear and easy to use.

Fancy features

Yeah, we’ll have to skip the fancy features this time.

Conclusion

Which features mean more to you? Emerson’s wirelessHART to connect into your control system with 10 years of battery lifetime? Or WIKA’s Bluetooth setup and datalogger?

Choose wisely, my dumplings.
