The professional planner / executing company is responsible for selecting an immersion sleeve that is appropriate for the intended application.
Current local rules and regulations are to be observed, in particular:
• VDE / VDI 3511 Technical temperature measurements
• DIN 43772 Control technology – metal protective tubes and extension tubes for liquid-in-glass thermometers, dial thermometers,
thermocouples and resistance thermometers – dimensions, materials, testing
• VDI Guideline 2035, page 2 – water related corrosion; preventing damage in hot water heating systems. Stainless steel tubes are
should be selected for cooling devices, well water and applications involving contact with food.
Ordering example: Immersion sleeve with length 100 mm,
Stainless steel PN 40: AT 100
Nickel-plated brass: ATM 100
