==========================
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.

great video. I am a flow meter manufacturer and in the process of acquiring HART for my devices
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.

Great to hear that, Fuat! Thanks for sharing.
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.

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.
