Instruments for a temperature range up to +280 °C (536 °F) or up to
+450 °C (842 °F) have a distance piece between process fitting and
electronics housing. Ths distance piece is used for thermal decou-
pling of the electronics against high process temperatures.

The spacer may be incorporated in the vessel insulation up to max.
50 mm (2 in). Only then is a reliable temperature decoupling guaran-
teed.
