Standard Protective tubing material Permissible temperature in dry air
Note 1:
JIS ceramic Cat.1 (PT1)
Mullite, high alumina, etc. 1,500°C (See note.)
Note 2:
JIS special ceramic (PT0)
Recrystallized alumina, fused alumina, etc. 1,600°C (See note.)

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-N 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.
