Product review: Rosemount 5300 level transmitter

Hey, let’s start the next chapter of product reviews! Today, we’ll look at Rosemount 5300, an excellent example of a guided wave radar currently available.

But first, how’s it going so far? If you’ve been reading along, then I’m sure you’ve become more familiar with level measurement. You also know now that non-contact radar devices don’t work for every situation and that guided wave radar makes a good alternative, especially for low dielectric constants or interface level measurements.

In the market, you have plenty of options from different vendors, and frankly, they don’t have many differences among them. This week for the product reviews and comparison, we’ll go over two high-profile devices, checking the features and finding out how they can help your process. And Rosemount 5300 from Emerson is out first choice.

Before we dive in and review Rosemount 5300, let me ask a question! Are you new here? If so, then I have one tip before you start to read – follow the recommendation below and enjoy!

Grab a smoothie, take a seat, have a read, and draw your conclusions!

Whatcha got there?

The Rosemount 5300 guided wave radar uses time of flight (ToF) to do its thing. You can learn more about ToF here on Visaya in this article. As I mentioned before, the 5300 can work in products with low dielectric constants (DC). The probe you use will determine the minimum DC you need. For instance, the technical documents say you need 1.2 with a coaxial probe.

And of course you need accuracy, which you find by scaling out the device using your process requirements. The Rosemount 5300 claims an accuracy of +-3 millimeters or 0.03 percent of the measured distance. That’s pretty good!

Design-wise, the Rosemount 5300 works like most Emerson sensors. Sadly, that means you can’t set up the transmitter locally. You need a handheld or a field network for remote access through a plant asset management (PAM) system. I vote remote access for the best procedure. However, even with remote access, sometimes you have to go into the field, and a local setup can save time in checking your data.

The dielectric constant and type of the probe also dictate your maximum measurement range. The manual says you can get up to 50 meters, but only with a flexible single lead probe in a product with a DC value of more than 6.

Still more limitations pop up with pressure and temperature. You’ll have to choose the right materials for your housing and probe and whatnot. In general, you can apply the Rosemount 5300 between -196 and 400 degrees Celsius and through a large range of pressures, depending on your tank connections. You should check out the product data sheet for those.

What can it do?

Besides level measurement, the Rosemount 5300 can provide the interface level, level rate, temperature, and volume of your application! Sounds good, huh? Of course, Emerson also provides a list of recommendations to guide you around the limitations of the device. For example, high levels of contamination, buildup, or vapor can cause errors.

Moreover, you have different probes for particular applications. The Rosemount 5300 has five probes as standard – rigid single lead, flexible single lead, coaxial, rigid twin lead, and flexible twin lead. For example, if you have fibrous liquids, then you shouldn’t use the coaxial, rigid twin lead, or flexible twin lead. But you can apply the rigid single lead or flexible single lead.

Why should I care?

You can integrate the Rosemount 5300 into a variety of automation systems using analog, HART, Foundation Fieldbus (FF), or Modbus protocols. You can also connect a wireless adapter and send data wirelessly to the control system.

No PROFIBUS here, but that’s no surprise, since Emerson prefers to play on the FF field. If you want PROFIBUS, you can either keep looking or sneak in with a converter. Do what suits your application and wallet. And if you have a complex application or just want to know what’s going on inside the tank, the Rosemount 5300 has an echo analysis for you to study.

As for fancy features, these aren’t the droids you’re looking for. But that’s okay, because it makes a long product review shorter! So consider the Rosemount 5300 for your next application, and remember to compare it with other players on the market!
