Hey folks, I need some recommendation on some good, accurate temp fittings. I want to use them in the tubing *:D*:D

I'd rather its not aluminium, unless its nickel plated.

I will be using them at those positions for some testing that i am planning to do. After that i would like to use them in the XSPC restops. So it would be nice if it was one of those "screw on" temp sensors:D

i was looking at the one from koolance (im not keen in those products though)
http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_346_203&products_id=22067

Does bitspower have something similar? I saw this one
http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_346_393&products_id=23347
but is there a version with a body like the one from koolance above?

any help is appreciated


PS:
i am also looking for some valves so that i can swap radiators easily. Any better solutions than this alphacool one?

D-Tek have something like this (http://www.flabbergast.com.au/inline-temperature-probe-1-2.html) for sale here.

I have a temp probe included in my T-Balancer that's brass. Not too sure what else is out there.

Just a note, it's about fluid dynamics. In a short loop where water flows only a few seconds in a component, like it is with a PC watercooling loop, the temperature will be to the 1/2°C or less the same in any point of the loop. Putting a sensor before and after the radiator, or even before and after a CPU/GPU WB, won't give you any information. These sensors have an accuracy of 1°C at least, so you won't see any difference. One sensor/loop is all you need

In WC, the only useful temperature is the Water/Air Delta

So, you're surely loosing your time/money using two of those sensors.

You see I've given up on saying that to people. I've had so many disputes with 'engineers' who aren't really engineers or people with a little knowledge. Seeing that you have brought it up, yes only 1 sensor is needed unless you have a large reservoir [like 1L+] that would take 30 mins to equalise.

:up:

Exactly, on a typical PC watercooling setup, the water temperature is to the 0.5°C or less the same at any point in the loop.

It takes time to get your water hot let's say to prepare a tea, so don't imagine your WB heating the water in the few seconds it passes through it, or the radiator to cool it.

i will be measuring water/air (2 sensors to measure air-in rad) delta anyway..i wanted to take any small differences into account but guess you have a point there though..so i guess i can best incorporate one with my xspc restop.
I do need some recommendation on a sensor with a minimum amount of error though...

Just so you know, I wasn't having a go at you :D. I'm just remembering all those awesome moments when a lot of people want to debate this fact.

What about those D-Tek sensors? They aren't aluminum so it should be ok. I know you can calibrate the sensors on the T-Balancer.

i know. i have been reading these forums for a long time and i am aware of the temps in a loop. Although i will be logging temps for about 1hour i should have a low margin of error anyway, i wanted to make sure i dont end up with a sensor that is 2C off the actual temp and make the results less reliable :D The heat load on the testing wont be massive so i want to be able to measure small differences one way or another

anyway, can the probe in the D-tek be unscrewed? it would be easier for me as i want to incorporate it with the Restop without ruining the looks :D

Those Koolance sensors, as near as I can tell, don't seem to work with anything but a Koolance system.

Bitspower or alphacool, there both pretty much the same probe in a different casing. So either one would work fine. I do like the bitsbower one a little better because the tip doesn't extend down to far. Use a DD or Bitspower T fitting inline and your all set. None of those type probes are any more acurate than the others.

I've got a couple of these in my loops and it looks like they can, the probes are threaded and are just screwed into the t then sealed with some clear resin. They don't look like standard 1/4" threads though, they look like 3/8" or maybe smaller

+1 for the bitspower. I have both and the bitspower fits into an EK reservoir without having to drill through the center divider as with the other longer version.

Yes, the bitspower looks great, but also there's this one which look short and slim

Just tape a normal flat temp sensor to the brass end tanks of your rad. Much simpler / cheaper and less unsightly than fittings within the loop.

Cheaper, yes, less unsightly, don't agree.
Also, you mean fitting it outside? Well, there will be a delta of some degrees between outside brass and actual water. Furthermore, the sensor will be affected by ambiant air temperature.
An in-loop sensor is the most precise way to monitor your water temperature

Actually, that's exactly what I did before I got my inline temp sensor...and it was about the same. I used a thermal pad between the sensor and the rad (put it on the back of the top, where the inlet barb's flow hits the inside and turns down), then put a neoprene pad trimmed to fit over the sensor to hold it in place and protect from ambients. Worked great.

But, IMHO the inline sensor is cleaner, and I had a spare hole in my res for it.

could be very interesting indeed. Nice way how you isolated the sensor

Is it worth measuring the air in and out of the rad or just the air in temperatures? My plan was 1 water sensor in the res, and 2 air sensors for each rad, one on intake for ambient and one on the exit of the rad.

Air "out" won't give much info you can use. The best delta to measure is Ambian (Air in) - Water

what matters is the air in because thats used to cool the rad. unless you want to measure how warm you can keep yourself in the winter by putting your face close to the rad, keep the air out sensor out of the equation :D
