Understanding Temperature Sensor Technology: RTDs, Thermocouples, and Thermistors

[@Grx-z1b]

We appreciate your work RealPars, you're doing a very good job. Thank you.

[@realpars]

Thank you very much! We appreciate your support.

The reaction chart used for the NTC thermistor is somewhat confusing because it's backwards. Temp should be the vertical and resistance be the horizontal. Since the temp is unknown, the arrow of activity should start in the middle space, drop to the left lower corner. Either is correct with the attempt to keep both charts the same, but shown different, like the 1,100 page electronics book in front of me. They are used in gas tanks for low fuel LED's. Inside a metal can, hanging off by itself and the fuel keeps it cold. Remember, a resistor in series with an LED's behind the dash. So current is off until fuel gets low. The resistor limits current to the NTC thermistor so when un-covered, it gets warmer and allow 0.030 mili-amps to reach the bulb, turning it on. It is used on imports, motorcycles and a larger number of domestics. The can provides ground so path to ground is thru fuse, resistor, bulb, thermistor to ground. Easily added if desired.

2:42 min. How much is "a small amount of electricity?"

[@realpars]

Hi there, Thank you for your question! Well, your question applies only to the Thermocouple. Thermocouple is an active device, meaning it produces a small amount of millivolts (mV). The RTD and the Thermistors are passive devices, meaning they have to be hookup to an electronic device that supplies the power. Regarding “a small amount of electricity,” it depends on the type of Thermocouple used and manufacture. To help you understand, here is some information and a link for your review: Ideally, the reading should range between 12 mV to 15 mV. If the thermocouple outputs voltage below 12 mV, there is a significant drop, meaning that it is defective and needs to be replaced. And again, depending on the type of Thermocouple used. instrumentationtools.com/how-to-calculate-thermocouple-temperature-by-measuring-the-output-millivoltage/

Very very nice teaching sir. Your examples make me laugh. Very interesting examples. Nice teaching.❤

[@realpars]

Thank you so much, @KishorChide-sl8tr! We're glad you enjoyed the teaching style and found the examples interesting (and funny!). Your kind words mean a lot. Happy learning!

[@EricPham-gr8pg]

Can L.E.D. Light and infrared sensor and U.V. All work together to get correct temperature and verify it too. But foods polution would make everything meaning less

[@sanojvgeorge]

Thanks 😊😊

[@krushnalmahajan417]

Great work

Hi, good lesson 😊

[@realpars]

Glad you liked it!

[@janezhang-ZonGon]

thanks for you video,dear friend,so RTD and thermocouple all could be used in food processing machinery,what is their different?RTD is good for food processing or thermocouple better?Thanks

[@realpars]

Thanks for your comment, Jane! I will happily go ahead and share this with our course developers. Hopefully they can add this to the list for future video courses.

Hello, Where does PT100 /1000 comes in the picture here? If not? In that case why? I thought pt100 are pretty common?

[@realpars]

Hi there, Thank you for your question! We have more than one video on KZbin about this subject. I suggest you look at the other ones we have to help answer your question. Our Pro membership will give you access to more information and a certificate after you complete the lessons. kzbin.info/www/bejne/banIo5ynhbasnrM Hope this helps, and happy learning!

[@genantamtam9364]

@realpars thanks for the answer but it didn't answer my question. My question is where does PT100 comes in the picture? I have learned that there are 3 different types of temperature measures, RTD, T/C and thermistors which are mostly located in motors. How about PT100? Is that a 4th solution or?

Thanks

[@JayLikesLasers]

Great video! Subscribed. As a bit of constructive criticism, the technical content was good, although the analogies could do with some work. I'm not sure if they were trying to be funny, but the tone of the video makes it sound like it's just chatGPT garbage: For example: "That's like trying to shoot a basketball from really far away and getting it in almost every time" and "Up to 2000 degrees Celsius; that's even hotter than the hottest day in Death Valley". Analogies could be really powerful when done right.

[@qtprot]

Agreed. The analogies were very off, UNLIKE AN RTD

[@Stomachbuzz]

I was going to comment the same thing. The language in this video was very off compared to other RealPars videos.

[@JayLikesLasers]

@@Stomachbuzz I'm not certain the audio's not AI enhanced text-to-speech. I'm now convinced the script was AI generated. Weird that it wasn't reviewed to fix this. Concerned that much of the popular online content will become AI driven content farms.

[@scottodonnell7121]

Also, the vocabulary needs to improve. Electricity is a form of energy, and energy can neither be created or destroyed. It merely converts from one form to the other.

[@sudhanshunayaksk]

Dear sir make a video regarding BBD /sfm sensor & it's working principle .....,

[@realpars]

Thanks for sharing your topic suggestion, I will happily go ahead and add this to the list.

[@haidarmohamedsami3867]

Hi there, thank you for the great videos and explantations ..... I didn't found your app on Iphone Appstore, can you guid me plz?

[@realpars]

Hi there,  We have recently optimized our learning platform which includes some highly requested features. We are happy to bring you these new improvements which will grant an even better learning experience, as a result we had to decide to no longer support the RealPars App. You can use our webpage to continue watching the video courses www.realpars.com Hope this helps, and happy learning!

[@terrogaming3398]

can you give me more information about Thermistors

[@realpars]

Thank you for your question! We'll consider creating a video to explain thermistors in detail. Stay tuned!
