Have you heard about SMAR? Probably, the dudes in charge aren’t noobs in this game! I’m glad I had the chance to work with some of the excellent professionals that started their careers at SMAR in Brazil and now work for other companies around the world.
Even though the company is smaller than most of its competitors, it has an impressive range of wireless solutions. However, we need to dig deeper than wireless for this review.
Anyway, let’s welcome the TT481WH wireless temperature transmitter from SMAR! We’ll dive into the features and highlight the pros and cons of the product, to help you consider its possibilities.
Take a seat, grab a coffee, have a read, 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?
The TT481WH has a simple, functional design, looking almost like a junction box fitted out as a wireless transmitter. But let’s not judge this book by its cover, lest we miss a good opportunity. Will that be the case here? Read on!
You can connect a variety of sensors to the TT481WH, like RTDs, thermocouples, volts, and ohms, and it’ll send all data wirelessly. However, you have to choose your input before you buy the transmitter, which sounds like a limitation to me. Otherwise, it installs easily, always a plus.
I tried to figure out which certifications it came with and got bupkis. It doesn’t have hazardous area certification, as the document says “pending.” If you need this cert, then you need to check out other options on the market.
What can it do?
The TT481WH can easily solve your problem of monitoring a temperature point! You can choose a transmitter with four or eight inputs, giving you more flexibility.
When you need to replace old mechanical thermometers across the plant, the TT481WH makes a nice step up. The multiple inputs save money on installation, but the device doesn’t offer much signal range. Depending on where you need the transmitter, you may have to install a repeater on your network.
You have a good accuracy, +- 0.03 percent, and you can set it up with a handheld or a laptop on various platforms. Surprisingly nice features on such a simple device!
Why should I care?
First of all, the TT481WH can save you money. The device itself costs less than other options, and with four or eight inputs, you can monitor several things in the same area!
Its simple installation will save you time too. You can do it through your field communicator, as long as you have the files necessary for full access. It sets up just like all the other wirelessHART transmitters on the market, and with the files, you can use different platforms.
The SMAR website claims a battery lifetime of up to seven years, but the manual says four. What’s the real deal here? And what’s up with the internal display? It’s inside the enclosure. Why does it even have a display? A mystery.
In general, the TT481WH from SMAR can go in all sorts of applications, and the wireless communication provides faster and cheaper installation. Not bad for one of the little guys!
