The sensing component of ZC0012 surface temperature sensor's probe adopts NTC thermistor, which is sealed in a metal cavity. When measuring, the probe directly connects the object to be measured, so the probe responds very fast. With ceramic technology, NTC thermistor is mainly made from metallic oxide like manganese, cobalt, nickel and copper. All of 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 smaller 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 inhibiting.
Specification
