Thermocouple protection tube


SG-28 silicon nitride ceramic is widely used as a thermocouple protection tube. Due to its excellent high-temperature performance, the service life is more than one year.

Compared with cast iron, graphite and other materials, silicon nitride will not be corroded by molten aluminum, thus ensuring the accuracy and sensitivity of the measured temperature;

Silicon nitride ceramics have low wettability to molten aluminum, so on-site maintenance is basically unnecessary.
