    Type R & S Standard Thermocouple "Isotech 1600"

    Type R & S Continuous Thermocouple

    Type R and Type S
    Gas Tight Assembly
    Premium Grade Wire

    The Isothermal range of Thermocouple Standards are the result of many years development. The type R and S standards will cover the range from 0°C to 1600°C.

    The measuring assembly comprises a 7mm x 300mm or 600mm gas tight 99.7% recrystallized alumina sheath inside which is a 2.5mm diameter twin bore tube holding the thermocouple.

    The covered noble metal thermocouple wire connects the measuring sheath to the reference sheath which is a 4.5mm x 150mm stainless steel sheath suitable for referencing in a 0°C reference system. two thermo electrically free multistrand copper wires (teflon coated) connect the thermocouple to the voltage measuring device.

    The thermocouple material is continuous from the hot or measuring junction to the cold, or referencing junction.

    The 1600 is supplied with a certificate giving the error between the ideal value and the actual emf of the thermocouple at the gold point. For types R and S thermocouples, manufacturing tolerances are small and, therefore, the use of a standard reference table is particularly apt. A few calibration points, only, are required to determine the small differences between the characteristics of an individual thermocouple and the standard reference table. As an example of consistency, 48 Isotech thermocouples calibrated at NPL, had a standard deviation of the differences from the reference table value at the gold point (11, 364V) of only 7V, equivalent to about 0.5°C. Thermocouple characteristics are sufficiently smooth to allow interpolation of deviations from the reference table to be carried out over fairly wide temperature spans without introducing unacceptable errors.
