I can't believe I'm asking this question here, but I don't see a better place. Sorry if this is the wrong newsgroup; if it is not, please include the name of the correct newsgroup in your flame. :) (I haven't had to post a question to a newsgroup, well, since google news appeared...)
I'm doing a simple project that involves measuring the temperature in a refrigerator. Not controlling, just measuring. You'd think that would be easy, and I'm sure it is. The web presence of high-end scientific thermocouple manufacturers and low-end circuit examples must be creating too much background noise!
Anyway. Suggestions for sources of midrange (or even better, /cheap/)
4-20mA temperature sensors with reasonable accuracy? I'm really lost here! :) At this moment, my options seem to be either a) spend hundreds of dollars per sensor, or b) build everything from scratch. Please say it isn't so!Thanks, not in advance, but just for getting this far into my question, tom
