ABB SensyTemp TSP300-W

Hey, anyone out there? Of course, y’all want a new product review! Today we have a outstanding product from the market. This company created a really cool solution to battery life in temperature measurement, and the installation is pretty easy! After learning more about this device, I’m wondering why more companies don’t have solutions like this.

So this brings ABB back to Visaya! My friends from ABB have a transmitter with fancy functions to make your life easier. I know you want that. Naw, don’t lie, just welcome the TSP300-W! Let’s dive into the overview about its most important features so you can decide on the TSP300-W as a possible solution for your next temperature application.

Take a seat, grab a vodka (drink responsibly, folks), and draw your conclusions!

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

Whatcha got there?

This transmitter from ABB has a bunch of cool features, so let’s start with the communication. It has wirelessHART already built in, although maybe you don’t use wireless on a daily basis yet. Wireless provides great monitoring, as long as you don’t need critical or fast control. Wireless devices save money on installation, implementation, and integration with your control system, and these three Is are better than two.

You also have the option of different installations. If you want do the standard, putting it into your process with a thermowell and all that, then you certainly can. However, if you want a simpler setup, you can go with a surface sensor.

This option gives you a sensor that you can install on the pipe surface, practically click and go. This sensor makes installation so much easier and cheaper. However, most of the time the standard setup gives you better accuracy and performance.

So you’ll have to weigh your needs to make your choice.

The transmitter also offers different types of sensors and a local display for setup and visualization. The electronics come with the sensor in this case, but you need a certain distance between the electronics and the pipe to avoid problems from high temps.

And last but not least, it has certification for hazardous area applications. If you have a zone 0, zone 1, or zone 2 hazardous area, this device can handle it. You can find more info on that in the manual.

What can it do?

What does everyone want a temperature transmitter to do? Bingo! Measure temperature! And it does indeed.

The surface sensor can measure a range from -40 to 150 degrees Celsius, and the transmitter can withstand temps from -40 to 70 degrees Celsius. If you want the traditional installation with the thermowell, the range of the TSP300-W will depend on the sensor you choose.

But wait, there’s more! The TSP300-W has a really cool feature, a built-in energy harvester system! Basically, the harvester provides energy for the transmitter battery, increasing the battery life. Most of the time, this issue answers the question of whether to go wireless or not. Here the answer is YAAASS.

Why should I care?

If you want a good temperature device, put the TSP300-W on your list. If you don’t know much about the wireless world, then you’re in luck! We have a ton of wireless content here on Visaya.

As far as accuracy and performance, the different sensors and classes reflect differences in accuracy. Pick the best one for your application and have fun!

For my two cents, I like surface sensors. They give you a lot of advantages in installation, maintenance, and replacement. I believe surface installations will become common for more applications than we can imagine.

By now, you probably already know temperature isn’t the fastest variable in your process. Surface sensors can provide update times from 4 seconds t0 60 minutes, giving you all kinds of possibilities for your control system.

If you worry about battery life, choose a device with an energy harvester like this one here. It has a thermoelectric generator (micro-TEG) that’ll recharge the battery through the temperature differences between the process and the environment.

That doesn’t mean the battery will last forever, but if you stick with it for five or seven years, you may get to see the “replace battery soon” diagnostic at some point.
