Description:
NTC Temperature Sensor is a detection element that feeds back the results to the system. It is also called thermistor or probe. Its principle is the resistance decreases rapidly when the temperature rises. NTC(Negative Temperature CoeffiCient)refers to thermistor phenomenon and material with negative temperature coefficient, and the resistance decreases exponentially when the temperature rises. NTC temperature sensor is mainly used in household air conditioner, auto air conditioner, refrigerator, stove, deep fryer, induction cooker, soybean milk machine, electric oven, kitchen utensils and appliances, floor heating,3d printers etc. temperature measurement and control.
NTC thermistor temperature sensor for a variety of applications in many parts of our life. Our NTC sensor are manufactured using sophisticated, state-of-the-art techniques to deliver high quality products suitable for the most demanding temperature sensing applications. The temperature sensors we use are created from a precise blend of raw materials and processed using proprietary techniques that result in superior discrete components, probes and assemblies.
Feel free to browse each category to find the sensor or assembly you need. If you're unsure of the type of thermistor sensor or assembly that fits your requirements, our expert application engineering personnel can assist you in making the best selection or in designing a special sensor or assembly specifically suited for your application. Simply fill out the Sensor Application Form and send it to us to provide us with the details.
