Instruments for a temperature range up to +250 °C (482 °F) have a
spacer between process fitting and electronics housing. This spacer
is used to thermally decouple the electronics from the high process
temperatures.
Information:
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.
