5k 10k NTC Thermistor Air Conditional Temperature Sensor High Precision Of Resistance Value And B Value
NTC temperature sensor is a commonly used temperature measuring instrument. It is generally composed of NTC thermistor, probe (metal shell or plastic shell, etc., extension lead, and metal terminal or connector). Its main feature is that the temperature within the working temperature range- The voltage relationship is a straight line. This second development of temperature measurement and temperature control circuit design can complete the temperature measurement or temperature control circuit design without linearization processing, simplifying instrument design and debugging.
