Hi there -
I'm looking for a relatively low-cost, moderate accuracy circuit that will sense temperatures up to +200C (+400F). The IC temperature sensors I have found so far seem to be limited to +125C, although I did locate a sensor from another manufacturer that claims to sense to +150C.
What are my options for a sensor circuit that will operate to +200C? Am I limited to a thermistor-based design, or are there other options?
I recommend looking at RTD’s. This is the most accurate temperature sensing solution for the temperature range you are looking at. The XTR108 is a good way of doing signal conditioning on RTD’s.
