產品描述

A thermistor is a type of resistor whose resistance is dependent on temperature. Resistors are always made of ceramic or metal composites. NTC thermistor is actually the temperature sensor that uses the resistance properties of these resistors to measure the temperature.  



NTC Thermistor are electronic components which reduce the resistance when the temperature increases. The material used in a thermistor is generally a ceramic or metal, while RTDs use pure metal mostly.


Thermistors typically achieve a greater precision within a limited temperature range, typically -40°C to 130°C.


 


 


Properties of film temperature measurement series:


- Small and light, convenient to mounting


- Good electrical insulation property & Safety


- High stability and reliability


- High sensitivity for thermo induction
