• Downstream from pumps (no danger of vacuum)

Thermal insulation
In the case of some fluids, it is important that the heat radiated from the sensor to the
transmitter is kept to a minimum. A wide range of materials can be used for the required
insulation.
NOTICE
Electronics overheating on account of thermal insulation!
‣
Observe maximum permitted insulation height of the transmitter neck so that the
transmitter head is completely free.
NOTICE
Danger of overheating with insulation
‣
Ensure that the temperature at the lower end of the transmitter housing sensor housing
does not exceed 80 °C (176 °F)
NOTICE
The insulation can also be thicker than the maximum recommended insulation
thickness.
Prerequisite:
‣
Ensure that convection takes place on a sufficiently large scale at the transmitter neck.
‣
Ensure that a sufficiently large area of the housing support remains exposed. The
uncovered part serves as a radiator and protects the electronics from overheating and
excessive cooling.
