Hi
I am new to this site and have limited knowledge, just enough to get me in trouble! I also apoligize if this question does not fit this forum or if it is mundane to this group.
I am building a bio diesel processor to make fuel from vegetable oil. Part of what I need to do is warm the vegetable oil to about 140F to get a good seperation of the fuel and the glycerin. I got an idea to use the heating element from a hot tub (220volt AC) to warm the oil as I circulate in the mixing process. My question is this, do they make a thermocouple and controller that would sense a low temperature and trigger the heating element to come on, then when the temperature reaches 140F cut the power. This is opposite of what I know Thermocuoples normally do. If that is not possible, does anyone know of another way to control the heating element that I can use without getting too complicate?
Thanks in advance
