==========================
✅ Check out the full blog post over at

==========================
In this video, you will learn what HART protocol is, how HART is used with analog sensors, how a HART analog sensor works, and what advantages a HART analog sensor can give your operation.
Current-loop technology has been used for analog sensors for the past 4 decades to transmit important process data to the control system, whether that system is a DCS (distributed control system) a PLC (programmable logic controller), or a single-loop controller.
Current-loop data transmission is simple and cost-effective. Only a small amount of current (4 to 20 milliamps to be exact) is required over a single pair of wires for each current loop sensor. One 2-amp, 24 Volt DC power supply can “drive” dozens of sensors.
For current-loop analog sensors, the lowest measurable process value is called the Lower Range Limit, or LRL. The analog sensor will output 4 milliamps at this 0% reading. The highest measurable process value is called the Upper Range Limit, or URL. The analog sensor will output 20 milliamps at this 100% reading.

I learn something worthwhile with every one of your videos. Excellent!
That's amazing, Bob! Happy to hear that.
great video. I am a flow meter manufacturer and in the process of acquiring HART for my devices
Thank you for the video. I have learned something new today from you.
Hi Jakub, you're very welcome! Yes! It's such a good feeling when you learn something new. :)
Excellent video, really interesting known the protocol and also the history, the parallel view of the "bell 202" with the HART Protocol make clear the explanation!
This is the best subject for discussion , thanks 🙏 RealPars
You're very welcome!
I liked your video, you have made it in a concise and clear way that it is a HART protocol, its history and even how analog sensors work, the best part was when you explained the ASFK and gave an example of the telephone line.
Thanks for your support, Damian! Happy learning.
Great videos. Definitely going to checkout you courses since I program mostly s1200's with tia 14
Thanks a lot! Happy learning :).
Nice
Lol ok thanks
I would like to thank you for your videos. Best to date. Clear, simple, and really easy to understand. Thank you.
So nice of you, thanks a lot!
Excellent lecture. The voice and presentation are

aclamaciones! :)
What a great explanation. Simple and to the point! excellent for people who are starting with these topics
Glad it was helpful, Maikel! Thank you.
Very well explained. Simple, and to the point! I just subscribed to your channel and will be looking forward to more videos from you Sir!!
Happy to hear!
I feel both great joy and sadness watching these videos and it’s conflicting. Great joy in that I learn sooo much than in my own job in Operations, Process & Automation Controls. Great sadness and it saddens me to admit it here also in that I don’t learn this much in my own job in Automations dealing with all these components, devices, protocols and plc’s and that saddens me greatly. I started my career as a Operational & Mechanical Technician in Operations at Utility and Power Plants. I now more work in Field Service, Equipment Commissioning, Plant Startups and Automations. The engineers when they even try to explain stuff are never close to this clear in explaining anything at a simple level either. As my own company also don’t believe in training or sending anyone to training. Sadness to me. But great joy watching and learning to fill in the gaps in my knowledge watching these videos. Every video I see I can relate to something done in my job or where I wasn’t clear in how something worked. The easy explanations here fills in my knowledge greatly and with great joy. I can’t say just how much I enjoy watching the videos here and know it’s directly affecting my job and what I know as well when I look at the devices, components, plcs etc.
Thanks for this beautiful compliment, Ardent!
That makes two of us @ardentdfender4116

Wow, this is absolutely charming, demonstrating a complicated topic in an easy method 🎉🎉🎉
Glad it was helpful, Marey!
I work with DeltaV and this video explains to me why I have to import DD files all the time when the new transmitters were installed.
Great to hear that!
Thanks for the great video guys, really informative!
I have a question though, which is not clear to me from the explanation.
Regarding the wired networking of multiple sensors, how many wires will you have in the end?
Is it a 1-1 connection for each of the sensors, or can you somehow impose the wiring of all of the sensors involved and end up with 2 in the end, with the capability to access or request data from whichever one you wish at any given time?
Thanks and keep up the good work!
Most networked, or bus-connected, sensors operate with 2 wires, (+) and (-). The difference between bus-connected and single sensors is that in bus-connected, the many sensors are connected in series, with a Bus-in and and Bus-out connection. The "out" from the last sensor in the bus returns to the common connection of the circuit. With a single sensor, the "out" returns directly to the common connection of the circuit. The two wires form a current-loop circuit and there is a (+) and (-) wire, with the signal overlaid on top of the circuit as communication moves from (+) to (-). That is a little bit of an over-simplification, but both wires are always used in communication because both are required to complete the electrical circuit.
Just to add that while communication and power will be carried over 2 wires only for as many HART sensors connected in parallel, however you are still limited by the PLC card or data logger limitation where each sensor will utilize a single channel off the master card.
very useful info..
Excellent explanation of HART protocol, I found it a very informative video.
Glad you enjoyed it, Boris! Happy learning
Good information. Thanks
great explanation on the subject
Thanks, Franko!
Thank you so much for such an amazing explanation ♥
Glad you enjoyed it!
My god you are amazing at teaching. I was wondering why you were talking about bell 202 modem standard, until you linked that same concept to HART and then boom, I understood! Thank you for the video!
Glad we could help!
FANTASTIC EXPLANATION
Thanks a lot! Great to hear that.
very good explanation helped me a lot to understand the subject, very detailed
Glad to hear that!
Remember, in a power outage, an analog phone will keep working as it has its own power supply. good to have a backup 'dial' phone without the battery. you can still call emergency, do not need batteries or power.
Can you make video for flow meters and wet and leg type level transmitters
Have you watched this video? th-cam.com/video/_pL7bGEF52s/w-d-xo.html
