Customized Refrigerator Defrost NTC Thermistor Temp Sensor SFHB20170203

Short Description:

Introduction：NTC Temperature Sensor

NTC stands for “Negative Temperature Coefficient”. NTC thermistors are resistors with a negative temperature coefficient, which means that the resistance decreases with increasing temperature. They are primarily used as resistive temperature sensors and current-limiting devices. The temperature sensitivity coefficient is about five times greater than that of silicon temperature sensors (silistors) and about ten times greater than that of resistance temperature detectors (RTDs).

How the NTC temperature sensor work simply explained

Hot conductors or warm conductors are electronic resistors with negative temperature coefficients (NTC for short). If current flows through the components, their resistance decreases with increasing temperatures. If the ambient temperature drops (e.g. in an immersion sleeve), the components, on the other hand, react with increasing resistance. Because of this special behavior, it also referred to an NTC resistor as an NTC Thermistor.
