Choose to use double platinum thermal resistance what are the advantages

Is double platinum thermal resistance is the common type of temperature sensor, the main component is the thermal resistance, six wire and four wire system, the difference of the two wire system lies in six of the wire with a temperature compensation is on every branch line, the main purpose is to better improve the measurement accuracy. Because of the double platinum thermal resistance in the whole is widely used in industrial automation industry, so choose double platinum thermal resistance is the main advantage of what?

one and the same location can be two different points of measurement; 2, can be a standby, so maintenance is more convenient; Three, because there are two, so can make the two contrast each other to determine the temperature measurement is in line with the requirements; Four, in fact, the double platinum thermal resistance advantages is that the temperature of the multiple locations can be accounted for as to the same casing, in multi-point temperature measurement, can choose double platinum thermocouple, heat resistance or and the insertion length can be according to the location of the measuring temperature for choice; Five, double platinum thermal resistance can also be used for redundancy or standby.
