Product Review: Endress+Hauser iTHERM TM401

Today, we’ll review the iTHERM TM401 from Endress+Hauser. If you work in industries such as food and beverages or life sciences, then you know you can’t install just any product in your plant. These industries require hygienic and aseptic applications to create products that adhere to stringent standards. In that case, you may want to consider the TM401.

Let’s see the pros and cons of this modular resistance temperature detector (RTD), and how it can work in your application. Stay with me, and we’ll find out together! And of course if you have more questions, drop them in the comments below.

Whatcha got there?

As always, I like to review the device design here, even though it’s usually not a big selling point for automation devices. The compact iTHERM TM401 has a clean and straightforward design. Nevertheless, it offers a list of options to beef it up for a better user experience.

E+H pitches it mainly at the life science and food and beverage segments around the world. Because of this focus, it has to follow international certifications for these segments. The TM401 has a wide range of these – EHEDG, FDA, ASME BPE, and more.

What can it do?

It can measure a wide range of temperatures for the above-mentioned industries. But let’s dig deeper into the specs.

Designed for hygienic and aseptic applications, this device has a measurement range from -50 to 200 degrees Celsius (-8 to 392 Fahrenheit). It also comes with a selection of process connections, such as triclamp, microclamp, and Varivent. You can see the entire list here.

On top of that, you can install the iTHERM TM401 in pressures up to 50 bar (725 psi). It has a protection rating of IP69K, common for these segments, but you can only use it in non-hazardous areas.

Furthermore, this RTD will integrate into your system with either analog or HART communication.

Why should I care?

The iTHERM TM401 brings all the specs and features you need to measure temperature in hygienic and aseptic processes. For the terminal head, you can get aluminum, stainless steel, polypropylene, and more. And the protection tube and thermowell come in 316L stainless steel. Accuracy, always the primary concern in process automation, follows Class A (acc. to IEC 60751) in this sensor.

Finally, the outer protection tube is six or eight millimeters, with an immersion length of up to 400. If you want to read more about the iTHERM TM401, you can visit the device page here.
