Anybody knows where I may buy dozen of different thermocouples for measuring temperatures. I need to measure both water and exhaust gases temperatures, well I may calibrate it myself after wiring to a datalogger.
Water temperature thermocouples should have a range 0-120 C, exhaust thermocouples up to 500 Сelsius.
Better if these thermocouples have threads for easy replacement, and their nets nights me soldered into copper tubes.
Where to buy temperature sensors?

Amazon has them...
Some other sites that have a variety of sensors.

Can your controller take an RTD input rather than a thermocouple?

Got it. Thanks guys.
What advantage does RTD have over thermocouples?, never worked with RTD before.

There is not a huge difference or advantage between them. TCs use TC leadwire, RTDs use regular copper leadwire. For a coal boiler application the accuracy of either will work fine, although TCs are more accurate for a narrower temp range. RTDs have a wider temp range than TCs and tend to be more stable and repeatable over long periods of time. TCs are cheaper than RTDs, how much cheaper depends on which type you get.

Top brand TCs and RTDs can be found all over at a big discount in ebay, new old stock.
