I need a sensor I can stick into a hole drilled into the side of a coal stove. Something topping out at about 1000 degrees F or about 500 degrees C (or so).
I did the digikey thing but my search term is too broad and with 10,000 items including the term "thermal", I am not getting anywhere. I can say that anything called a "termisistor" tops out at about 200 degrees C so I know that is not what I need, but I simply don't know what the name of the part I do need, is. Bottom line, I need a doo-dad to measure a fire topping out at about 1000 degrees and be read by an ADC. Gimme what you got.
I remember replacing the thermo couple in gas (CH4) burning heaters without ever rethinking my budget. So it must’ve been lower than this price.
Of course, I don’t have the specs (like max temp) on the devices on hand, but I’m sure you could get a cheaper model in the hardware store. Well, over here in Holland anyway.
As I understand it, a TC gives off a voltage, rather than provide you with a resistance. Something to do with a bi-metal thingey and a thermo-electric effect.
“The principal advantages of thermocouples are that they are inexpensive (you can get thermocouple wire pair in rolls to make your own, often for <$0.50/ft.), provide moderately accurate and consistent meas urements, and operate over a wide temperature range (from <0°C to >1000°C).”
