Thermistor


Thermistor
Thermistor (English: thermistor) is a device or component or sensor electronics used to measure temperature. The basic principle of the thermistorm is the change in resistance value (or barriers or werstan or resistance) when mtemperature or the temperature of the thermistor is changed. this thermistor a combination of said thermo (temperature) and resistors (gauges
prisoners). Thermistor was discovered by Samuel Ruben in 1930, and earned the right
in the United States patent number # 2,021,491. There are two kinds of thermistors
in general: Posistor or PTC (Positive Temperature Coefficient), and NTC (Negative Temperature Coefficien). Resistance value at the PTC will rise if temperature rises, while the NTC just the opposite.
