Rosemount 5300 vs. Honeywell SLG 700 Smartline

Hello, how are you doing so far? Yup, you are right! Here we are to compare two products. This article should be the last comparison with radars and level stuff, let’s change the topic a little bit, but later we can go back to level again, huh? Let me figure this out; maybe I’m gonna write another product review and comparison with two significant level players in the market. I’m gonna keep you posted!

I’d like to share a thought after a chat with a friend of mine! He hits me up last week to talk and give feedback about the content in general. In fact, the conversation brought me good insights, but the most relevant thing is that he liked the level content. He is a level expert, and for sure his opinion about our level topics is more than relevant! We have a bunch of articles about level measurement waiting for you, click here and find out.

For a long time, I’ve never been a big fan of radars, but I had the chance to see that the majority of problems could be easily solved. Frankly, this is a result of the lack of knowledge about this technology. Seeing with the vendor’s eyes or the guys responsible for developing new products, it is far from the customer reality, and that distance makes everyone believes that all is good.

However, when you are beside the clients in the field, you can experience the challenges, the lack of information and so on. These points make me think of the gap from the manufacturer to the customer reality, but it’s better to come back to the comparison.

Making a long story short, let’s see “what’s up?” with the new participants! On the right side, we have the experts from Emerson Automation Solutions, and the Rosemount 5300! On the left side, The dudes from Honeywell have another guy to the fight today! Let’s say hi to the SLG700 Smartline!

We’re gonna find out how these instruments can fit in a new application. Let’s dig deeper into the features and check the pros and cons of each one. Meanwhile, you can follow the deal to draw your conclusions, right?

Take a seat, grab an ice cream, have a read, and draw your conclusion!

Disclaimer: This product review examines only features, not performance. If you’ve used this device, feel free to share your experience in the comments.


You have a good impression when you see the SLG 700 SmartLine from Honeywell. The device is compact with a simple design, reminding you the pressure transmitters. The SLG 700 SmartLine has a neck a little bit longer than the others radars in general, the display and the possibility to have the push buttons are positives aspects from the product. They are economical in my point of view, maybe a larger screen and touch buttons could be a good improvement here.

On the Emerson side, the design of the Rosemount 5300 is different than others radars on the market. It’s not bad, don’t get me wrong! In fact, what’s bad is the lack of local configuration in Emerson’s products. However, we’re in an IIoT age, where the remote setup and smart devices are the hype of the moment. Even though, I think that a local configuration through a display or push button can save a lot of significant time.


The SLG 700 SmartLine brings a conventional display, the screen is not fancy but at the same time is not bad at all. The display is an LCD with advanced graphics, where you can have information as a large PV, Bar Graph, trend graph, and other stuff. The Bar Graph and trends graphs are relevant features because you can have an easy visualization of the measurement range through the Bar Graph. In the trends graph, you can have the echo stem plots and somehow analyze the level measurement through the display. In fact, it’s not easy at all. However, it’s an interesting feature to have.

Furthermore, you have different idioms, and this option can improve your user experience. Lastly, you can install the display in various position, and you can install or remove the display in the field without issues.

The display from Rosemount 5300 is optional as well. However, the LCD here is simpler than SLG 700 SmartLine from Honeywell. You can see the basics level measurement from the transmitter; there is a table with more than 15 parameters that you can choose to show up on the screen. The screen has only two rows, where the first one will show the value and second one, which parameters you are reading, showing up the parameter name and measurement unit.

Measurement range and probes

Before you scale out the devices for your new application, you need to figure out if your range can fit in your application. For example, the SLG 700 SmartLine can be implemented in different liquids and solids up to 50 meters. When we talk about accuracy, the Honeywell inform a reference accuracy of +-3 millimeters, and the device can be applied in temperatures from -60 to 450 degrees Celsius, and pressure from -1 to 400 bar.

The SLG 700 SmartLine has three different types of probes, such as single wire, single rod, and coaxial. They don’t have a tablet with the technical recommendation for each sensor here, but there is software running online to guide you to scale out a new transmitter for your process. The Smartline level application and validation tool can run correctly on your phone, tablet, and laptop. You have a step by step, and at the end, you have the right device for the application.

When we talk about the Rosemount 5300, the device offers a measurement range up to 50 meters as well. The advantage here is the flexibility. It means you can apply the 5300 to liquid and solid level measurement. The instrument has a list of different probes; we can mention the standard rigid single lead, flexible single lead, coaxial and others. Here, you don’t have a cool and online tool as the guys from Honeywell, but you have a table with all limitation of each sensor, or you can download the toolkit to scale out your level transmitter.

Material, process connections, and protocols

If you have a hazardous environment, you need to have the right protection and also the right material. Furthermore, your device should support the environment conditions. Otherwise, the lifetime will be reduced. Both companies were offering material options to the housing, O-ring, and so on.

The SLG 700 SmartLine has different types of material to the wetted part, which means, the part with constant contact with the product. You have couple options. We can mention the stainless steel 316L, PTFE, Alumina, and others. The housing has two choices. The aluminum and stainless steel. The transmitter has a threaded connection and can be implemented in different types of process connections, giving you an excellent flexibility.

The Rosemount 5300 is not different, you have different material for the probes available, such as PTFE, Alloy 2205, SS 316L and more. You can have an Aluminum housing or stainless steel. The choice depends on process requirements and the certification necessary.  The process connection here is also threaded, and you can fit in different process connections.

Let’s talk about the seamless integration, or the intention to have an easy integration. The SLG 700 SmartLine had the traditional 4-20mA, HART, and Foundation Fieldbus. On this one, we miss the PROFIBUS  to give a broad range of possibilities.  The Rosemount 5300 has 4-20mA, HART, Foundation Fieldbus, and an additional protocol the Modbus. You have an additional option in this case, but we still missing the PROFIBUS here as well.

Fancy Features

Both instruments have advanced diagnostic, and this is not fancy at all. Next topic!

Information and documentation

The Honeywell website you can find information on it, but not quickly. And if you have to use your phone, make sure you have something else to do while you wait for the load times. The documentation is clear, and you can find the topics quickly searching for them. However, the tool to scale out the level transmitter works very well, and you can use on your phone and tablet. The problem here is a simple detail, the page is not https (Btw, this is a necessary requirement) and you can have trouble to open on your laptop for security reasons!

The guys from Emerson Automation Solutions have a good website; even if you navigate through your phone or tablet, you gotta a good experience. Furthermore, they have a clear documentation and tons of blogs and videos. Well done!


Both devices have similar features, and you have small differences when we talk about material, protocols, and displays. In the end, you need to scale out and find out the performance with your process requirements, and then check this details.
