5.2.5 Thermal insulation with diaphragm seal directly mounted
The device may only be insulated up to a certain height. The maximum permitted
insulation height is indicated on the device and applies to an insulation material with a
heat conductivity ≤ 0.04 W/(m x K) and to the maximum permitted ambient and process
temperature. The data were determined under the most critical application "quiescent air".
Maximum permitted insulation height, indicated here on a device with a flange:
