1、Temperature Temperature is a physical quantity that indicates the degree of heat and cold of an object. Microscopically, it is the intensity of the thermal motion of the molecules of an object. Temperature can only be measured indirectly by certain characteristics of the object as it changes with temperature, and the scale used to measure the value of the object's temperature is called the tempe...

PTC (Positive Temperature Coeffi Cient ) PTC is a thermistor with a positive temperature coefficient and a sharp increase in resistance at a certain temperature. thermistor phenomenon or material that can be used specifically as a constant temperature sensor . RT and RT0 indicate the resistance value at temperature T and T0, and Bp is the material constant of the material. The ...

Semiconductor thermistor materials These materials include single crystal semiconductors, polycrystalline semiconductors, glass semiconductors , organic semiconductors, and metal oxides. They all have a very large resistance temperature coefficient and high turtle resistance, and the sensitivity of the sensors made of them is quite high. According to the resistance temperature coefficient can also...

Several common applications of PTC thermistors PTC thermistor is a positive temperature coefficient thermistor that increases in resistance as the temperature increases. This kind of resistor is usually made of barium titanate, through different production processes, different applications need to be made into a special shape of the element, we often use its resistance-temperature, voltage-cu...
