I doubt it will work because the resistance and temp vs resistance gradient is very specific to the thermister. If the resistance is close enough you might be able to calibrate the controller against a known thermometer but even then the temperature reading might be off.]]> Wed, 01 Dec 2004 14:03:23 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=4196&PID=45463&title=diy-temp-controller-on-the-cheap#45463 <![CDATA[DIY TEMP CONTROLLER ON THE CHEAP : Do you think the old temp probe...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=4196&PID=45440&title=diy-temp-controller-on-the-cheap#45440 Author: flashmc

Do you think the old temp probe off of a titanium heater would work forthe  thermistor? I had one that I thought went bad and before Ithrew it out, I removed all possible usable parts, which included theprobe. ]]> Wed, 01 Dec 2004 08:46:54 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=4196&PID=45440&title=diy-temp-controller-on-the-cheap#45440 <![CDATA[DIY TEMP CONTROLLER ON THE CHEAP : Jon, I got a thermostat from NPS...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=4196&PID=42189&title=diy-temp-controller-on-the-cheap#42189 Author: seti007

Jon, I got a thermostat from NPS but I think it has a bad thermister, anyways I used the one from HD and it worked fine. You can always replace the thermostat if you end up damaging it ( just match the resistance value).

As for the Silicone, I dont know why it would leak over time as there is no pressure involved. In anycase if salt water gets in there, the resistance will change and the temp reading will as well. I will still use my old analog thermometer in the tank as a backup. I think that using it on the outside glass is not as accurate but will still pribably work.

Very cool Asad.  I've been toying with that idea too.  The only thing keeping me from trying it out was I wasn't sure where the thermistor was for the thermostat... you've solved that mystery!  Did you know that you can often find electronic thermostats at the NPS store too.  I upgraded my home thermostat to one from NPS (only cost $10). 

BTW, it's been my experience that even after siliconing the themistor/thermocouple salt will still get into the connection and corrode it.  I tried it with a remote sensing thermometer (it was a stocking stuffer a few christmas's back).  Maybe I just didn't do a good enough job with the silicone.  Let us know if it "stops working".  What I was thinking of doing was to tape or silicone the thermister to the outside glass.

I've been thinking about putting one of those nice digital things in my house, when I do I may just buy two or three so that I can give this a try.  It looks like it wasn't to hard.  But I can be all thumbs at times, like the time I was trying to enlarge a hole in a piece of plastic and ended up with 12 stiches, and a thumb that's still numb...

 

I didn't see anywhere that I had to cut anything, just soldier.  I think I can handle this one.

Nice project.  You should bring to the meeting and share it with everyone.
