2.2.4 Thermal insulation
Some fluids require suitable measures to avoid loss of heat or heat supply at the sensor. A wide
range of materials can be used to provide the required thermal insulation.
When insulating, please ensure that a sufficiently large area of the housing support is exposed.
The uncovered part helps heat transfer and protects the electronics from overheating (or
undercooling). The maximum permitted insulation level is indicated in the following graphic
(1 = flanged version, 2 = wafer version). These apply equally to both the compact version and
the remote version of the sensor.

Caution!
Risk of electronics overheating!
• Make sure that the adapter between the sensor and transmitter and the connection housing
of the remote version are always exposed.
• Note that a certain orientation might be required, depending on the fluid temperature  ä 7
