What is an NTC Thermistor?NTC Thermistors are temperature-sensing elements made of semiconductor material that has been sintered in order to display large changes in resistance in proportion to small changes in temperature. NTC Thermistor resistance can be measured by using a small and measured direct current, or dc, passed through the NTC thermistor in order to measure the voltage drop produced. NTC Thermistors are an incredibly accurate category of temperature sensors. In general, NTC thermistors are composed of sintered ceramics consisting of highly sensitive material with consistently reproducible properties of resistance versus temperature. more info>> |
