SHEATH TYPE THERMOCOUPLE
DATA SHEET
FTJ, K, E
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 ele-
ment.
Unlike ordinary type thermocouples, it provides excellent
sensitivity and vibration resistance, and is designed to per-
mit easy bending work.
FEATURES
1. Thermocouple tube is very small in size, providing excel-
lent sensitivity.
2. Adoption of integrated structure has improved the vibra-
tion resisting characteristic.
3. Easy bending work allows fabricating a long-sized thermo-
couple for easy measurement even in a place where ordi-
nary 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 se-
lection 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.

Note: Tolerance means the maximum allowable limit of
the value calculated by subtracting the
temperature of the temperature measuring
junction from the temperature obtained by
converting the thermal electromotive force by the
reference thermal electromotive force.
|t| is the value indicated by temperature (˚C) that
is not related to + or - symbol of the measured
temperature.
