Hello I have a problem with a temperature sensor it has 1 Mohm of resistance at ambient temperature and according with the specification the value has to be 2 Kohm, I think that the circuit is open but I do not why, do you Know any reason for open circuits, or for the sensors failure.
Measuring 1 Mohm or more on a 2 pin temperature sensor such as a thermistor or a resistance temperature detector? Then it's probably permanently destroyed. Sorry. I usually destroy things by putting too high voltage -- now I know 120 V is too high :-). I suppose it's also possible it failed from over-temperature or other stress. --DavidCary 17:05, 30 August 2008 (PDT)
