PT sensor having polarity?
Since PT Sensors or Platinum Resistance Thermometers are based on the changes in resistance as the result in temperature changes I would not expect them to be polarity sensitive. The work differently from thermocouples which actually generate a voltage.

look at the controller your connecting it to, ive connected pt100 sensors to certain controllers and the temperature reading counted in reverse until i changed polarity. ive connected them to different controllers and it makes no difference
