Thermistor for measuring/controlling temperature

@RimstarOrg 10 років тому

This week's video is an electronics one all about using thermistors, what they are and how use them to measure and control temperature. I especially had fun doing the simple circuit where I heat up the thermistor with a hair dryer until that causes the fan to turn on. And then the fan cools off the thermistor, causing the fan to turn off!

This sensor is for attaching to the cooling system in a particular model of car, so you'd have to make your own mounting system. To turn on a fan below 100C you can do what I did in the video. But it probably won't turn on at 100C. For that you'd need to add a resistor so that the total resistance adds up to something that would result in the right current for the fan. You also have to consider what temperature the fan should turn off at. Search google for "pexsupply snap disc" for a better way.

Thanks for this video! Any pointers on how to read a thermistor's label? Does "8L10 10002" mean it acts like a 10K resistor at room temperature?

@joshdat3reak 2 роки тому

Thank you for your video! I have an off road buggy and the fan isn't switching on to cool the engine. It looks like it's the same type of thermistor so I'm going to check the resistance now and see if its working!

@RimstarOrg 10 років тому

I don't think it's a rectangular hyperbola since it looks like when it's near freezing the graph isn't parallel to that axis. I don't know what the fact that it's a curve means. Maybe it's something to do with the molecules or the bonds between them, but looking online I couldn't find any insight. And thanks! Glad you're still enjoying the videos.

I just opened up with only PC power supply I have (outside of a computer) and it has SCK 054, an NTC thermistor. I don't want leave this power supply intact though in case I ever need it as such. At least I now know where to find them. Thanks!

Can we arrange this thermistor in series with AC current

@RimstarOrg 9 років тому

Santosh Kulkarni I don't see why not. It's just a component whose resistance changes with temperature. en.wikipedia.org/wiki/Thermistor talks about its use for current limiting.

@RimstarOrg 10 років тому

According to the graph, cold water won't boil sooner than room temp water. Cold water will have a faster heat transfer rate while it is still cold, but once the cold water reaches room temp, the heat transfer rate will be the rate it should be for room temp water. So once the cold water reaches room temp it will take the same time from then on as room temp water does.

@RimstarOrg 10 років тому

An IR gun, one of those handheld infrared guns that you point at things and then the temperature is shown on a digital display would work.

The only way I know to do that is create moving positive ions. It'd be atoms that are ions with positive protons and neutral neutrons in the nucleus and negative electrons surrounding the nucleus but there would be less electrons than protons, and so they'd be positively charged. In fact, I've done it in my "How to Make/Build a Lifter or Ionocraft" video. The positive wire electrode strips electrons from atoms in the air to create positive ions, which flow down to the negatively charged foil.

@RimstarOrg 10 років тому

It isn't a capacitor symbol, though I can see the resemblance. It's supposed to be like two walls facing each other. When they're close together they restrict the flow of electrons i.e. high resistance. When they're farther apart they allow more flow i.e. low resistance. Oh well.

@firoxlion 10 років тому

Interesting, but why did you use a capacitor symbol for the NTC?

Found a great one just now. Take a look for small green bulb type devices attached to back of large heatsinks. Got one from another PC power supply, it was 7.3K at rest in approx 80F. Blew on it for 30 seconds and it went to over 8K, warmed it between fingers and it went down to 6.5K. Can only imagine fridge and sun values...pretty good temp sensor for free, once calibrated. Perhaps to keep an unpowered eye on transistors or other circuits, or part of indoors/outdoors actual temp sensor :)

@GlobalAwareness2525 10 років тому

My Whirlpool gas dryer isn't getting hot enough and the clothes never get dry, the gas flame works, it's just shutting the heat off too soon, so I bought what is called a thermistor in a sealed plastic case that screws onto the exiting chamber after the blower. This did not solve the problem. When I remove the thermistor as to not allow it to sense any warm temperature and left it plugged in the flame stays on endlessly. At first I assumed that even though the encased thermistor was new in the package that it might be defective straight from the manufacturer, but now that I see this video there are a few of these disc-like thermistors attached inside the dryers wiring harness, they are not seemingly positioned in any specific spot as if to sense temperature, but just part of the wiring, I always thought these were perhaps some sort of resistor, but instead they are identical to what you call a thermistor. When I was at a dead end on what to do next then this video helped me to decide that the next thing I should try is to replace the short harness sections that contain these thermistors. Thanks for making this video.

@RimstarOrg 10 років тому

No need to do the setup with common resistor. I just connected a 1 kohm, 2 watt resistor to my meter and put the same hair drier on it for 1 minute, twice as long as I did in the video, and the resistance increased by only 8 ohms. Common resistors aren't affected by temp. as much as thermistors. The VARIAC is a 3 amp, 240VAC one which I bought off-the-shelf. I'd recommend higher amperage for more usefulness. Maybe salvage from old power supplies but usually buy second hand since they're costly.

That was fun :) Just grabbed what I thought to be one off an old PC power supply and had a little look. Green disc 'SCK 2R55A'. Thought may as well try it. Only 2.7ohms at 80F room temp. Held in hand it went to 2.5ohms, in front of a small fan, up to 3.3 ohms. At 10x those figures it would be similar to your automotive one...did a search and it is one, but nothing like as variable as that one you show. Still, I now know something more about them, cheers.

I want to build a circuit to trigger a buzzer if the temperature in my fridge gets too high. I lost a bunch of groceries after an electrical snafu in my home and wanted to prevent that from happening again. Do you have any other videos which might help me understand how to design a battery supply which only began to feed power to something should another power source fail? I suppose I just want to learn how to design a portable back up battery. Portable as in I can easily carry it from one place to another and portable as in it could be easily adjusted for use with most DC supplied electronics.

@RimstarOrg 8 років тому

+iADT I don't know. There's no data on the box that it came in and I wasn't able to find a datasheet for it online when I looked before. Maybe you'll have better luck. It's a BWD part and the part numbers on the box are 020-7913-8 and WT691. It's normally used for car engine systems somewhere. But if you have a non-automotive thermistor, one that isn't in the brass casing like mine, then you can probably look up some numbers online.

Does anyone know where i can get a temp sensor that turns on fan at 95 degrees no matter wat

@samerawaragi3041 2 роки тому

Thank you for making this video. A small question is how to know if a thermistor is malfunctioning? In my car A/C, the compressor cycles soo much and especially in cold weather. When I jumped the connection; it stayed ON. It is trying to control the temperature to 4 degC but it seems too sensitive. Is thermistor can go bad or is it a design flaw in the circuit? thank you for your video.

@RimstarOrg 2 роки тому

I guess you'd have to isolate the thermistor from the rest of the circuit and then create a setup like I have in the video. Then set up a test circuit like I do in the video and see if it works. Or if you can't remove it enough from the circuit then try heating it with a hair drier.

And I'm glad to hear you liked my video. Thanks for watching.

@riccardogiuffrida9632 6 років тому

very good! but I have a question: what temperature reach the thermistor 1 k ohm when you apply 12 volt? it is very hot (about 85 C) and isn't dangerous if you put it in a fuel tank to have a low sensor that light a bulb? sorry for my poor English. Ciao.

@RimstarOrg 6 років тому

I don't know the answer for your first question. For 85C, search for the "ignition temperature" of your fuel.

I was thinking to M35 or 5D-11 would work. the heat goes on those brushless motors pretty high sometimes. I would like to find the right thermistor that it would turn on the fan around 150-175F. which model thermistor should i use do you think?

@RimstarOrg 10 років тому

I couldn't find any data on the M35. The 5D-11 has the temperature range.

So it could be thw right option. Let me give it a shot and i will post my experience. Thank you so much.

is thermistor in refrigerator works same as you mentioned in the video

@RimstarOrg 6 років тому

I'm not familiar with the ones in the refrigerator.

@DigGil3 10 років тому

Speaker and Microphone, LDR and LED, Fan and Thermistor: feedback systems galore! You could have mentioned that most common resistors also behave somewhat like thermistors. Interested on repeating that setup and comparing the curves? Also, I've been noticing your nifty-looking autotransformer. Do you mind giving details about it? Might it be salvaged from something I could get my hands on?

i need to measure the temperature of hat water inside the tube. i can make the hole for set up this thermister but m not getting how to put it. the water will be in contact with both wires. ????? can u answer ??

@RimstarOrg 9 років тому

kunwer singh Just make sure the water isn't in electrical contact with both wires by insulating the wires. To insulate the wires you can use heat shrink tubing, or liquid electrical tape, or anything else you can think of that would prevent the metal of the wires from getting wet.

@kunwersingh2893 9 років тому

RimstarOrg I forgot to tell you tat my planing to use it in heat exchanger which am designing. actually am thinking both of RTD and Thermister . Ican make its wire insulated but takes more time. I better use RTD .

Can you please tell me the specifications of the thermistor featured in this video

@RimstarOrg 7 років тому

I don't have any of the specifications for this thermistor since it's embedded in the automotive sensor. The info for the sensor is BWD 020-7913-8 WT691 but that probably won't help you much.

@sachinsherry8175 7 років тому

+RimstarOrg I just wanted to make a project on a thermally controlled fan just like you did for fun

Thermistor value?thanks

@jv1zz 9 років тому

how hot did your sensor get to turn on fan ?? also is there a engine coolent temp sensor that will turn on a fan at a 98 degrees

@RimstarOrg 9 років тому

J Vizz I didn't measure the temperature. If you're looking for something that isn't really for an engine then you might want to look at snap discs, like these www.supplyhouse.com/Fan-and-Limit-Controls-1880000 They come in a variety of temperature ranges. I have this webpage that talks about them specifically rimstar.org/equip/temp_control_circuit.htm

@kelumo7981 7 років тому

great vid,but Sir did I hear you well at 0:10 ?did you say "cold water boils faster than hot" ?

@RimstarOrg 7 років тому

Thanks. And nope. I said I did an experiment to determine if cold water boils faster than hot. The experiment I did is in this other video (ukposts.info/have/v-deo/cHuSn258f3eC2qs.html) and the result was of course no, cold doesn't boil faster than hot.

@kelumo7981 7 років тому

RimstarOrg Oh thanks I watched the video twice and understood it ,many thanks

Is temp the dependant or independent variable?

@RimstarOrg 8 років тому

+Ross Butters It's the independent variable.

I would like to use something like this to turn on and off an electric pvc sprinkler valve. On at 65 F, off at 75F do you have any suggestions?

@orionarts8478 8 років тому

or visa versa

@RimstarOrg 8 років тому

+Jonathon Shafer You could use a circuit with a thermistor, that's in the right range. Or you could try looking for a snap disk (rimstar.org/equip/temp_control_circuit.htm), though those temperatures are a little low for that.

@orionarts8478 8 років тому

+RimstarOrg it is to regulate water temperature inside a large tank for fish...if that helps with ideas. I want to recycle the water from an underground collection tank also using the home hot water to balance temperatures.

If you're going to use a thermistor to control more than small power then use it to control a power transistor (a FET or Darlington) that the power flows through.
