7¡¢Assembling
thermocouple
¡¡¡¡As a sensor to measure and adjust the temperature,
an assembling thermocouple is generally
used to form a complete set with indicator instruments
and directly measure the temperatures of
the surface of such media as the liquid,steam and g-as
and solid in the temperature range of 0
to 1600¡ãC in various production pro-cesses.Range of temperature
measured and tolerance of
thermo-voltage of various models of thermocouples
