Protection tube for high temperature assemblies

TWF16
Protection tube for high temperature assemblies ©Endress+Hauser

For processes with high process temperatures like cement production, steel treatment, incinerators

Measuring points with extremely high process temperatures require these special ceramic or metal protection tubes made from special materials. They protect from mechanical and chemical damages in the process and increases the life span of the used sensors. This leads to: Cost savings for maintenance of the measuring point, quality improvements of the products and increased plant safety. It is specially designed as replacement part for the high temperature TC thermometer TAF16 by Endress+Hauser.
