INQUIRY

The function of the high-temperature S type thermocouple compensation wire is to extend the thermal electrode, that is, the temperature measuring system formed by the connection between the cold end of the moving thermocouple and the display instrument. The compensation wire is generally used on the thermocouple, and the insulation layer and the sheath of the high temperature compensation wire are different according to the requirements of the environment. The sheath material is fluoroplastic, low smoke low halogen polyvinyl chloride. And a few alkali-free glass filaments.
S type thermocouple compensation wire Compensation principle

The thermocouple may be several tens of meters away from the thermometer. The temperature of the cold junction (outlet end) of the thermocouple is different from the ambient temperature of the thermometer (even up to several tens of degrees). If a common copper wire is used, according to the thermocouple principle, the temperature difference potential will be generated at the wiring, and measurement errors will occur. If the S-type compensation wire (which must be matched with the thermocouple indexing number) is used, the metal material selected can produce the smallest possible temperature difference potential at the wiring, and minimize the temperature measurement error. That is, move the cold junction of the thermocouple to the thermometer. The voltage drop of the long-distance transmission wire, because the input impedance of the thermometer is high, the thermoelectric potential generated by the thermocouple (millivolt order) transmission current (micro-A level) is small, and the voltage drop loss on the wire is small, in general Next, within the error range. Therefore, there is a thermocouple transmitter, input thermocouple signal, output 4-20mA, so you can not use S-type compensation wire, but also can be transmitted from a long distance.
