thermal sensor question

thermal sensor question

thermal sensor question

(OP)
I have a thermal sensor which is supposed to be Pt RTD, in a vacuum chamber. But I measured the four lead output of the sensor outside the chamber is ~6.5 Ohm in room temperature. But Pt RTD should have a ~100 Ohm resistance in room temperature. Does anybody know any RTD has this range of resistance in room temperature? Thank you!
