What is Thermistor and difference with RTD

thermistor symbol
Thermistor is a sensor to sense temperature.It is basically a resistor whose resistance varies with temperature.

Thermistor=Thermal+resistor -the naming of thermistor.



Difference between Thermistor and RTD:


  • As construction material only ceramic or polymer is used in thermistor,where RTD is made of pure metal.
  • As temperature response RTD's are useful over larger temperature range and thermistor for -93 to 130c.
