Your videos are awesome sir specialy for the working persons in industrial Automation .. plz make one video using TIA hardware and software configuration
Nice work and great explanatory! And your animations are very detailed and I think that somebody that starts now will be really helped from your videos. I have a question: why the proximity sensor would create a spark? Isn't it transistor based?
Not all proximity sensors are transitor-based. In the video, we saw that NAMUR sensors are solid-state devices that do not generate a significant amount of energy on switching, and therefore, are suitable for hazardous areas. Electromechanical switches can spark and should not be used in hazardous locations.
Hello, @syedaslam2856 . Thank you for your question. We explained it very simply in our video. Here is a more technical explanation: A NAMUR sensor operates by changing its internal electrical impedance when a target object is detected, resulting in a variation of current flowing through the sensor, which is then interpreted as a signal by a dedicated amplifier; essentially, it acts like a variable resistor where the presence of a target alters the current level instead of providing a simple on/off voltage output, making it ideal for intrinsically safe applications in hazardous environments due to its low power consumption and current-based signaling. Here is a more technical review for you: instrumentationtools.com/why-we-use-namur-output-sensor/. You can find lots of technical info on the internet
Hi @Prasad R. The switch operation shown in our video is accomplished by an electronic device turning off or on. There's no actual real switch therefore no sparking potential.
Hi there. Thanks for your question. May proximity sensors have make and break contacts. Unfortunately, make-and-break contacts are not acceptable in some environments. That's where NAMUR sensors are useful as the change of resistance replaces the make-and-break contacts. I hope that answers your question?
@@realpars I mean, how can making and breaking contact in proximity switches cause electrical arcs since they are based on solid state devices they chouldn't cause any risk when they make-and-break
Dear sir Videos is Very helpful but Kindly one request you please text should be keep inwhite colour. Block is not visible properly and missing diagrams and very helpful information and pictures.
Hi there. Thanks for your question. There’s no quick answer. The maximum cable length between a Namur sensor and an IS barrier is determined by several factors such as the type of barrier, and the specific Namur sensor. For example, the input impedance of the IS Barrier must be extremely high to ensure that cable resistance is not a factor. Compliance with relevant safety standards such as IEC 60079 also needs to be consulted.
Hi thanks for your great training video. Please make video about analyzer sensors ,like oil and gas analyzer sensors. I working in petrochemical plant and there are a analyzer house for analyzing oil and gas. Thank you and good luck
no, you can have different type of sensors (pressure, distance, limit switch etc.) all ATEX certified. Note they can have different protection concept (NAMUR being intrinsically safe)
@@zeli There are ATEX intrinsically safe devices marked as ia, ib or ic depending on the zone you use it. So basically NAMUR is something that the rest of the world calls ATEX intrinsically safe device.

I haven't seen proper industrial automation TH-cam channel like yours nicely done
Thanks for your support, happy learning!

I work in Turck can you make some videos on RFID IO link and fieldbus
Normenarbeitsgemeinschaft für Meß-und Regeltechnik in der chemischen Industrie, let's keep going!
Nice job! I do these for a living and you did a great job of explaining.
Thanks for your kind compliment, Jim! Great to hear that
Quality of video is unique
Thank you so much, Mohamad!
The best in the automation world
That's an amazing compliment! Thanks for sharing.
Thanks so much RealPars.
You're very welcome - happy learning!
Please RealPars,
Could you please explain hall effect sensing in dvc 6200 positioner which is used in control valve?
Hey!
Thanks for your comment and your suggestion. I will pass this on to our course developers!
Thanks for sharing and happy learning!

In NAMUR we measure the output in mA ? Not like in typical proximity we measure output in voltage. Please explain.

Once again thank you very much.
You're very welcome, John! Happy learning, and feel free to reach out if you have any questions along the way.
Thank you
Well done mate thanks
Thank you, Maximos!
Nice explanation. I have one doubt. Namur sensor also have switching mechanism. Why it is not creating a spark while opening and closing.
Hi @Prasad R. The switch operation shown in our video is accomplished by an electronic device turning off or on. There's no actual real switch therefore no sparking potential.
Thanks
Can you make session about control loops like cascade, split range, ratio, feedforward, feedback..
Look up "Basic and Advanced Regulatory Control". Great book covering that stuff.

how proximity switches make and break contacts, aren't they supposed to be based on solid state components?

What's the max lenght for the câble ?

you forgot to tell that it is possible to detect wire break with these types of sensors :)
Thanks for adding that, Jan!
could explain more plz
@@benjah2782 if there is no current flowing there is a wire break.
