Temperature sensors may be marked Pt 100. What does it mean?

Thermistor will typically have

When the cable length from the temperature sensor to the place where we want to read the temperature exceeds approx. 10 meters we normally have to, in case of a Pt 100, in some way compensate for the cable resistance. Do we also have to do this if we choose to use a T802 temperature sensor?

Thermo-elements will typically have
