Thermocouple k-type KP KN chromel alumel alloy
Thermocouples are used in processes to sense temperature and is connected to the pyrometers for indication and control. The thermocouple and pyrometer are electrically conducted by thermocouple extension cables / thermocouple compensating cables. The conductors used for these thermocouple cables are required to have similar thermo-electric (emf) properties as that of the thermocouple used for sensing the temperature.
Our plant mainly manufacture thermocouple wire, strip, and cable, and they are used in temperature measurement instruments. Our thermocouple products are all made abiding by GB and also IEC584-3 (International standard).
Thermocouple strip can be used to produce thermocouple connector's hollow pin, thermocouple spade, and thermocouple connector's contacts.
