Ceramic thermocouples have a Wide range, specially ceramic sheath with a protection sheath of SS grade tube material as knowing holding sheath which is used as mounting & protection of ceramic sheath, Ceramic thermocouples are specially manufactured for high temperature as continues temperature measuring this type thermocouple are used in Ceramic & Glass industries.
Type “R” (Pt.Rh.13% - Pt.) and Type “S” (Pt.Rh.10% - Pt.) are used to measure temperature up to 1600°c Maximum. Thermo element pair is protected by two or three ceramic sheaths of various types depending upon working temperature and environmental conditions.
Ceramic protection tube type KER 610 –with 60%, 80% Al2O3.
Type KER 710 –recrystalised – high alumina tube with 99.9% Al2O3 available in 24 mm, 20 mm, 15 mm, 12 mm, 10 mm dia.
Holding tube made of SS304 are used to hold ceramic sheath with head complete with ceramic terminal block with nickel plated terminals.
