Hi, I have a hot water boiler that comes with some electronic control unit, but this unit does not have switching for electric heater inside a boiler. So I am building my own control unit, where I would like to use temperature probes that are allready installed (4). The problem is that I don't know a thing about what kind of probes are there. Only think I can say is that it has two wires and metal housing of a probe is an inch long and it has 1/5 of inch diameter.
So can I measure the resistance to know what kind of probe this is? Does those probes have linear relation between temp and resistance?
