What would be the best type of sensor to measure temperatures from around 65c to well over 200c, I am not sure the max temperature. I made a solar collector from some old double glazed window panels, and a few metal grids from the backs of fridges, these are mounted on a copper sheet and everything painted black, I had a bit of a mishap, I soldered the joints of the copper tubes, and even at this time of year after a day or so with no water in the tubes, the inside of the sealed box has reached 90c on a cloudy day (the copper temperature of back plate). So now I am thinking in summer those joints are not going to hold!! I will have to get dad to braze them, I have tried to find out but cant find the information for max temperature, some of these home solar sites suggest that some parts inside the glass box can reach over 200c.
I sort of believe it seeing how hot its got on a dull winter day! Anyway I want to measure the temperature of the pipes, panel,glass and water, water isnt such a problem but not sure the best way to measure the collector panel. Anyone running home solar water heaters here?
