Sic ceramic silicon carbide thermocouple protection tube
As a temperature sensor, the thermocouple protection tube is usually used with temperature transmitter, thermostat, temperature indicator, etc. It is called the process control system. With this system operation, the thermocouple protection tube can be used to test and control all the temperatures of fluid, steam, gas, surface of solids, etc.whose temperature is between 0-1800 degree Celsius during various production processes.
Since each materials has its own characteristics, it is requested to be easy installed, aseismatic with large temperature testing range and high mechanical strength considering of both tested items such as the item’s temperature, flow velocity, corrosivity, etc. and tubes including diameter, thickness, length, mechanical stress, thermal shock capacity, price, etc. The materials of thermocouple protection tube could be chose according to the situations and needs.
