ZC Surface Temperature

The sensitive element of ZC0012 surface temperature sensor probe adopts NTC thermistor, which is sealed in a metal cavity. When measuring, the probe connects directly those samples to be tested. So its response speed is very rapid. NTC thermistor is mainly made from metallic oxide such as manganese, cobalt, nickel and copper in the way of ceramics. All these metallic oxide is of semiconductor property, so its conducting way is completely similar to semiconductor materials like germanium(Ge) or silicon. When temperature is low, there’re few current carriers(electron and hole) in these oxide materials, so its resistance value is relatively high. As temperature rises, there’re more current carriers, so its resistance value reduces. NTC thermistor can be widely used in situations like temperature measurement, temperature compensation and surge current inhibition.
