Insulating tubes for mounting thermocouples can be produced with one to ten bores. They are available in round or oval form and can also be inserted with slots.
Protection Tubes, Insulating Tubes and RTD Elements
Technical Ceramics in Temperature Measurement and Control
“Protection tubes, insulating tubes and RTD elements made from CeramTec technical ceramics are the first choice in temperature measurement and temperature control whenever safety and stability are required.”

Ceramic protection tubes, insulating tubes and RTD (resistance temperature detector) elements from CeramTec are used in manufacturing devices for temperature measurement and control. Their resistance against aggressive atmospheres – even in the most demanding conditions where temperatures reach up to 1,700° C – make CeramTec products the first choice whenever safety and stability are required in these processes.
The various CeramTec alumina ceramics used, such as Rubalit® C799 or Dimulit® C610, are characterized by their excellent electrical insulation and high mechanical strength. CeramTec also offers the slightly porous material Pormulit® C530. CeramTec protection tubes and insulating tubes that are finished “as fired” conform with the DIN 40680 standard.

Insulating Tubes

Protection Tubes
Protection tubes that are closed on one end and act as protective sheaths are manufactured in a single process step using Rubalit® C799 and Dimulit® C610 and offer effective protection against penetration from the outside atmosphere into the measurement system.

Resistance Temperature Detectors (RTDs)
CeramTec produces resistance temperature detectors – also known as RTD elements – with exceptionally high purity and extremely tight tolerances. RTD multi-bore tubes from CeramTec are produced with Rubalit® C799 and used by RTD manufacturers worldwide.
