Is this a K Type sensor?

Jessey,

Take a look at STEVECHASTAIN.COM I have his book on building a small foundry, and highly recommend it. You might also take a look at Lindsay Books, they reproduce a lot of older technical manuals, and they carry the Dave and Vince Gingery books. I have the Gingery book on building a charcoal foundry, and they are easy to read, and inexpensive. Both books will give you ideas as to where to find materials and supplies for melting metal.

Hi Jerry,

Yes my friend did order some plans for a furnace then he found an advertisment on craigslist for a furnace and got a smoking deal on the one he bought. It's a manufactured unit made by Johnson Gas Appliance Company that runs on natural gas. Neither one of us has ever done any castings before so it's going to be very interesting to say the least. Have you been using your furnace much?

Thanks for the clarification on the MAX6675 Steve and the code to get it up and running, that's cool. I phoned Digi-Key and they have a 5 week waiting period for a back order for the MAX6675. I will still get some of the MAX6675's but I think I'll phone Digi-Key tomorrow and see if I can get a couple of the AD595's especially if I can get some without the long wait, as I can't wait to get this project up and running. I'll let you know how I make out.

Thanks
jessey

Jessey,
I haven't done nearly as much casting as I would like, but I've had fun with aluminum. A friend rebuilds diesel engines, and saves me the bad pistons. The aluminum used in the pistons contains alloys that make it machine nicely, and I have a small lathe that doesn't get used as much as it should either! Got to save something to do for retirement right?

Anyway, if you go to Maxim's website they will let you order samples of the Max6675. You might be limited in the packages that they offer in samples. You can order parts direct from them too, but the shipping would cost more than one or two parts.

Jerry.

I think with the MAX6675 you're pretty much limited in package selection anyway... 8 pin SOIC is all that's shown in the data sheet.

I don't know why DigiKey said they have a 5 week back order on the MAX6675. According to their website they have several 1000 in stock...
