I'm about to order my Pid and Thermocouple for my temperature controled forge setup and this is what i have considered buying. First off the pid, I dont need any ramping or fancy stuff so i am just going to get a standard model but i dont realy want a small one as i want it to be big and easy to see and program. so i was thinking of getting a 1/4 DIN PID instead of a 1/16 DIN. but every refrence to a pid i have found online for a heat treat oven or forge uses the 1/16 DIN. is there a reasion why they use that insted of the biger one. here is the one i want. this is the link to it http://auberins.com/index.php?main_page=product_info&cPath=1&products_id=102
and it's picture
Will this work ok, i would imagine it would but i thought i would ask.
now next up is the thermocouple, as i'm going to be using it in my forge i wanted somthing robust and strong. i had looked at the ones from Auber, this one http://auberins.com/index.php?main_page=product_info&cPath=3&products_id=39.
but that one needs a proctive thermo well around it and that is another 18.00 http://auberins.com/index.php?main_page=product_info&products_id=40.
So i looked on the Omega site and found there Super OMEGACLAD® XL Heavy Duty Transition Junction Thermocouple Probes. they look perfect for what i need. here is the link and a picture http://www.omega.com/ppt/pptsc.asp?ref=TJ36CAXL_NNXL
also they have various diameter sizes from 1/16" to 3/8". I am thinking of going with the 3/8" size for derability and also just the fact of go big or go home
. Also from what i have read they are vastley better then the other ones on the market. i dont mind paying more for it if it it will be what i need. here is a graph from there site on how tempature stable it is a diffrent temps. they say it lasts tons longer then other thermocouples. here is a pdf of its specs http://www.omega.com/Temperature/pdf/TJ36CAXL_NNXL.pdf
I used the part number builder to design the probe and this is what it is TJ36-CAXL-38U-12. but it is 12" long and that was the shortest thay had listed. but i found out that if you change the 12 to 6 in the part number then search for it in the search box it comes up as a 6" one that needs one week to make. I think a 6" one would be easear to use as my forge is onley 12" long and i'm thinking of sticking it in through the side of the forge body and adding a little locking screw to hold it in place like how my burner is held to the forge. I am thinking of getting the Ungrounded junction as it look like it would give me a more stable temp reading and not get as affected by flame temp as it does not come in contact with the casing. here is a picture if the types of junctions.
It will cost me 52 bucks but that's not bad as it's onely a little bit more then the other one and the thermo well also it look like a killer thermocouple.
so i will spend a bit more then if i sorced everything off ebay but thats ok as i want the good stuff. any tips or comments on this would be great as this is all new to me.
