Monitoring Water Temperature
 

Anyone have a good idea for monitoring water temperature? A while back, Joe thought of coating a thermal diode in AS epoxy and sticking it in the side of a hose. What do you guys think about this? Sound doable?

If you have any exposed pipe (water block connections, quick disconnects, etc) I'd just thermal epxoy a thermal probe on the outside of the pipe, and insulate the outside exposed part of the probe. It would reach equilibrium with the water temps soon enough.

I suppose that's true... It wouldn't be quite as accurate as measuring the temp of the water exactly, but it'd be close. Actually though, I don't have quick disconnects so this isn't really an option.

the thermal sensors are actually waterproof...and most people have a fill hole in thier resivoirs...I just have my sensor dangling in my resivoir since thats the temperature of the water that will be going into my waterblock.

It would be a helluva lot easier than putting a small hole in a hose and sealing it back up good enough so that you were absolutely sure it wouldn't leak. And I'd bet that if you insulated the quick disconnect or whatever part you attached the sensor to (brass nipple, copper water block, etc) that it would be close enough to the direct measurement that you couldn't tell the difference after it reached equilibrium.

yeah, but if you put the sensor in the hose it will change alot faster...more reliable

Alives, I forget who I was talking to, but he/she said that submersing the temp probe in water would short it out.

All depends on what type of probe it is, and how it's wired. Most of the bulb type probes would have problems directly in the water without some kind of protection, but the thin brown plastic ones are sealed and wouldn't have a problem in water. I think putting a temp probe in the water in a setup like mine would be very simple as I have that one line that captures the air, with just a bolt in the top to act as a cap, would be easy to slip a probe down past that and into the water. Just gotta get myself a probe for that now.. http://www.procooling.com/ubb/wink.gif

Go for it una. Then report back http://www.procooling.com/ubb/smile.gif.

Heh, anyone know what resistance thermistor the CPVue/CompuNurses use? I need to buy one..

I put mine in a hole in a nylon connector I had...this way I can seal it better because its not flexible and the glue will hold.

good call..

i was thinking about a copper pipe.. (insulated of course) with a sensor attached..

btw.. if u bore a hole in a coldplate (3/8") .. how deep can the hole be without influencing the cooling potential? .. its for a thermal sensor..
its a rather big one... 4mm...

anybody knows a temp sensor for <60C ??

you could try infrared for 80 bux

im not sure about shorts but i tryed and took a t-connector and put the flat type thermister in it and sealed it with silicone sealant and did three cures to seal it really good ( my computer isnt covered in my home owners insurence ) wrapped it with tape at the end of the sealant and it work pretty good, you should make sure it dosent leak before installing it.

LMK if it works

Yeah... OCWC and Leufken both sell things like this now.

lol...I just bought one of those thermisters that Tom Leufken has that's already inside a coupler that you install inline...and it plugs into the motherboard...

funny thing is, I'm looking at my motherboard right now (KT7A-raid), and I don't think it has a header for it, heh

maybe I"ll try to cut and splice it onto a compunurse that I have

Yeah, my A7V133 only has 1 header, and I want a temp probe for the water going into my radiator, and the water leaving my radiator.. I think I'll just wire in a 3way toggle.. http://www.procooling.com/ubb/wink.gif

Go here and request some thermistors to try out. Rock over at HardOCP measured 40K ohms for you, but I cannot find any common 40K so maybe it was 50K Ohms? worth a shot http://www.ametherm.com/SampleRequest.html

also, request 10K ohm thermistors for the mobo probe.

theres my nylon connector with a sensor...very quick readings...hasnt leaked at all
