In this video, we’re going to introduce you to a very powerful group of devices called Smart Sensors.
The Smart Sensor plays a very important role in the Smart Factory of Industry 4.0 which is considered as the fourth revolution of the manufacturing industry.
The First Revolution brought us steam and water-powered mechanization.
The Second Revolution introduced mass production using electricity.
The Third Revolution established automated manufacturing processes using computers and robotics.
And now the Fourth Revolution has launched the Internet of Things (IoT) and the Smart Factory.
What makes a Base Sensor different than a Smart Sensor?
Before we get to that question, let’s review what a base sensor is, what it does, and how it is integrated into process control loops.
A base sensor is a device that senses something. For many years we’ve had sensors that can see, feel, hear, smell, and even taste.
In the world of instrumentation and process control, we define a Sensor as a device that detects changes in physical properties and produces an electrical output in response to that change.
A Thermocouple is a temperature sensor that will produce an increasing voltage across it when exposed to increasing temperature.
In industry today, thousands of thermocouples are connected to transmitters in temperature process control loops.
In the process control, we condition the thermocouple voltage and convert it to an industry-standard signal that represents our controlled temperature range.
OK...so...what if we had a sensor that did more than sense singular basic physical properties?
What if we had a sensor that also performs data conversion, digital processing, and can communicate to external devices and The Cloud?
In very general terms a Smart Sensor has a base sensor, a microprocessor, is communication-capable, and has some form of onboard diagnostics.
Smart Sensors are capable of a variety of functions and options. Smart Sensors can perform self-assessments and self-calibration.
They can detect issues such as sensor contamination, switch failures, and open coils.
Some Smart Sensors are capable of multi-sensing and can measure pressure, temperature, humidity, gas flow, and more.
Smart Sensors play a very important role in the new era of manufacturing intelligence. They will become more and more important as the industry develops increasingly sophisticated and complex processes.

Thank you so much for creating this video! It feels like we just asked for this last week!
You're very welcome! Happy to hear such positive feedback.
Thanks sir for a simple and powerful presentation.
A good, interesting, useful and refreshing video every week. Always 100 points.
That's amazing to hear, thanks for sharing that with us, Ricardo!
Happy learning
This is a nice way to start the week. Thanks for sharing so much good information
Happy to hear that, you're very welcome!
Thank you
Good video. Thanks. I take some exception to your video. In a plant environment the smart sensors are going to report results to a local controller/ data agrigator.
A local cintrollee is needed so that the plant is controlable when global internet is down.
A data agrigator is useful in that the sensor data is concentrated and sent as a more manage data package the a collection of individual sensors. Also only one device, the data agregator needs to have cloud authenication details.
Hi Glenn,
Thanks for sharing your knowledge and experience with us.
Happy learning!
Excellent
Best video 💯✨✨✨🙏
I'm doing an end of cycle project for my engineering degree on this topic, this was very helpful thank you
Glad it was helpful! Best of luck on your final project!
@@realpars thanks 🙏😁
Good effort, nice and informative content
Keep up the good work💪
Thanks for your support, Oussama! We appreciate that.
Good video . I have learned alot . Thanks 😊
Glad it was helpful!
Thanks sir.. Kindly make a video on interlocking
Thanks for the topic suggestion, I will definitely go ahead and forward this to our creator team. Happy learning!
When u 100k subs that time now itself watching every video really very perfect explanation keep it real pars u will reach very good position
Thanks for your support!
Well explained loving the video
Thank you, Moses!
Nice, very informative 👍
Great to hear that, Ashwin. Thanks for sharing!
Real pars finally reached 500k subs
All thanks to you guys' support! We truly appreciate that, thanks for sharing!
@@realpars Isn't that amazing!
@@4.0Solutions for u not that much big deal who will put their full effort making video for that channels each and every subscribers is very important
Good
good afternoon, you can have a video on a topic that explains what an interface and a protocol are, many people confuse or think that this is the same thing
Hi Poma,
Thanks for your comment and your suggestion. I will pass this on to our course developers!
Thanks for sharing and happy learning!
Great video
Glad you enjoyed it!
Thanks for video .I am new graduate from instrumentation engineering sadly I working in operation .I want to improve my skills in Programming of PLCs what can help me in that?
You're very welcome!

Keep making videos
is the output of the smart sensor always digital ? or it's always a current ? i had this as exam question.
Thank you for your question! Smart Sensors are available in various configurations tailored to suit your specific application. They can be fully digital, provide current output, or be easily configurable for your needs through dip switch settings or software. In the Industry 4.0 version, the options are plentiful, and numerous companies offer these products. To explore further, consider checking out the following links: www.omega.com/en-us/ us.rs-online.com/customer/login/?source=myaccount
Feel free to explore and find the best fit for your requirements!

What are open coils?
Solenoid valves and other devices, such as contactors, operate when current is passed through a coil of wire wrapped around a magnetic rod. This causes a change of position of a rod or other mechanism that closes a contact, changes a valve position, etc. If the wire is broken, it is called an "open coil", since the driving force for the coil is lost.
cool，
Industry 4.0 " internet of things" its far more advance than previous generations, but its has a security issue like "Hacking",
Because its connect it to the internet .
Good effort, nice and informative content
Keep up the good work💪
Thanks a lot!
