Resistance thermometers

Resistance thermometers, also called resistance temperature detectors (‘RTD’s).

Sensor with good linearity.

Pt-100 , Pt is the symbol for Platinum, 100 for the resistance in ohm at 0°C

.

Thermistor

A thermistor is a type of resistor whose resistance vary significantly with temperature

=> good sensivity

NTC – Negative Temperature Coefficient Resistors

PTC – Positive Temperature Coefficient Resistors

.

Thermocouple

Produce a voltage   =>  do not need external supply.

Excellent repeatability.
