Type C thermocouple temperature sensor: Type C (tungsten 5% tungsten 26% 铼) thermocouple is suitable for measurement within the range of 0-2320 ° C.

 

Because the C -type thermocouple temperature sensor can reach the temperature of up to 2320 degrees Celsius, they are widely used in spacecraft, nuclear reactors, industrial heating or any places where there may be extremely high temperatures. They are also widely used in high -pressure research. This thermocouple temperature sensor is very suitable for vacuum furnaces at high temperatures.

 

Type C thermocouple temperature sensor can be used for certain applications, but it is not suitable for most industrial process services. In addition to the expensive price, the harshity of many typical high -temperature process environments to tolerate many typical high -temperature process environments is not practical. There are several reasons, one of which is that tungsten exposure to oxygen will burn. Therefore, it must be operated under vacuum or inert gas, and it must not be used under the existence of oxygen with a temperature of 260 degrees Celsius. An example of this type of failure is that the glass bulb is ruptured.

 

In addition, tungsten will become crispy when heating and cooling within a certain temperature. In the incinerator or Claus device, even in the inert gas environment, normal vibration can cause crispy metal wire to break and cause failure.
