Note: The permissible temperature given for the protective tubing is
higher than 1,400°C, but the permissible temperature of the
thermocouple element wire is only 1,400°C. Therefore, the
protective tubing of the E52-PR@C can withstand high
temperatures momentarily to the levels given in the table as
exceptions, but the element wire will deteriorate quickly if the
thermocouple is used regularly at temperatures that exceed the
permissible temperature for the element wire.
