I have temperature reading system having PT1000 sensors. I need to measure temperature between -20 C and -200 C which these sensors. My question is how much they are linear at -200 C ? If I use two points 0 C and 100 C for calibration purpose and compare the reading with reference calibrated system and use first order statistics to calibrate PT1000 then how much they will be off at -200 C ?
