Lug type sensors can be easily fixed onto the heating system to measure the surface temperature. The element is encapsulated in glass bead in order to acquire little effect from oxidation. Besides, cooper pipe is characterized by its high strength, hardness and rigidity in low temperature. However, it may be susceptible to mineral acid and oxidation, which accelerates degradation. With its low water absorption, it has great water resistance when sealed into the resin head.
