Thermal resistance of main fuses can be divided into three different forms

Actually the main lead heat resistance can be divided into three kinds of different forms, and small below to learn together!

a, two wire thermal resistance fuses: each will be mainly on both sides of the thermal resistor connected to directly lead to the same wire resistance signal, we call this way two wire, two wire electrodes is very simple, but because of the connection wire is must exist, so the material will have a certain relationship, and the length of the wire of the two wire electrodes is only suitable for application in the low required measure precision of occasions. Two and three wire system thermal resistance lead: at the location of the thermal resistance of root to connect a lead, while the other end to connect two fuses, so we call it three wire, three wire electrodes is mainly used in bridge of form a complete set, can effectively eliminate lead to resistance to impact, so is the control of the industrial use more lead resistance. Three, four wire thermal resistance fuses: can on both ends of thermal resistance of the roots connect two different lead at the same time, we call it a four wire system, four pillars in the lead has two root is designed for heat resistance provides a constant current, so this way can be compared directly lead to lead to resistance to eliminate the influence of cause, it is often used for high precision temperature detection.
