For measurements with insulation, a layer thickness of 8 cm SiBa 20/150a was applied. Look
-
ing from the surface of the tank, a 6 cm layer of SiBa 20/150a was first applied. A 2 cm layer of
SiBa 20/150a/ALU50 was then finally applied on top of this layer.

EPL Da instrument - Complete device (antenna and housing) installed in Zone 20 (sur-
rounded by 200 mm dust):
Max. permissible ambient/process temperature:
+65 °C
Surface temperature:
Ambient/Process tempe35 K
Max. surface temperature:
= 65 °C + 35 K = 100 °C

dust layer):
Max. permissible ambient/process temperature:
+65 °C
Surface temperature:
Ambient/Process tempe35 K
Max. surface temperature:
= 65 °C + 35 K = +100 °C
