The measuring tips consist of a mineralized non-metallic sheathed cable. A connection base fastened to a shoulder ring serves for electrical connection. Two pressure springs serve to press the tip of the measuring unit against the bottom of the protective tube. This ensures improved heat transfer, reduces vibration in the measuring unit and compensates for thermal expansion and longitudinal tolerances in the measuring tip and protective tube. When adapting the design it is necessary to observe the correct dimensions for the measuring tip length and measuring tip diameter to ensure sufficient heat transfer from the protective tube to the measuring tip. Material 2.4816 - Inco 600 is used for the jacket on the thermocouple measuring insert.
