SHEATH TYPE THERMOCOUPLE DATA SHEET This thermocouple is firmly sealed with high-purity oxidized magnesium (insulating material) in a fine metallic protective tube without air gaps, together with the thermocouple element. Unlike ordinary type thermocouples, it provides excellent sensitivity and vibration resistance, and is designed to permit easy bending work. FTJ, K, E FEATURES 1. Thermocouple tube is very small in size, providing excellent sensitivity. 2. Adoption of integrated structure has improved the vibration resisting characteristic. 3. Easy bending work allows fabricating a long-sized thermocouple for easy measurement even in a place where ordinary type thermocouples cannot be used. 4. Thermocouple strand is not exposed to air, ensuring a long life with minimum deterioration or breaks of wire, unlike ordinary type thermocouples. 5. A variety of protective tube materials are available for selection according to applications. 6. Various types of terminals such as extension cable type, connector type, exposed type, terminal box type, etc., are also available for selection according to applications. Class : Class 1 2 3 Note: Class 3 is applied only for low temperature of less than 40˚C. Class 3 is permitted only for FTK, FTE.
