Excellent Stability NTC Thermistor Probe Ohm 100K Ttc 103 104 NTC Sensor For Electronic Product
NTC temperature sensors are usually composed of 2 or 3 metal oxides, mixed in a fluid-like clay, and calcined into a dense sintered ceramic in a high-temperature furnace. Oxygen-bonded metals tend to donate free electrons. Ceramics are generally excellent insulators. But only theoretically, this is the case for thermistor-type ceramics when the temperature approaches absolute zero. However, as the temperature increases to more common ranges, thermal excitations eject more and more free electrons. As more electrons carry current through the ceramic, the effective resistance decreases. Resistance changes very sensitively with temperature. A typical change is a decrease of (-)7[%] to 3[%] per degree Celsius. This is the most sensitive of any sensor suitable for use over a wide temperature range.

Working principle of temperature sensor
Using the NTC thermistor under a certain measurement power, the resistance value drops rapidly as the temperature rises. Utilizing this feature, the NTC thermistor can be used to determine the corresponding temperature by measuring its resistance value, so as to achieve the purpose of detecting and controlling the temperature.
