Ceramic Protection Tube Thermocouple

Custom Ceramic Protection Tube Thermocouple available with type K, R, S, and B thermocouples. Available protection tube materials: Alumina (3450°F), Mullite (3100°F), Silicon Carbide (3000°F). When using R, S and B platinum thermocouples high purity alumina tubes must be used to protect the platinum for contamination. Single or dual elements are available. Thermocouples with alumina protection tubes are susceptible to thermal shock and must be pre-heated before installation, and only then inserted slowly into the hot process to avoid fracture.
