4.2.2 Installing the Evaluation Unit
Note the following points when installing the evaluation unit:
Position the evaluation unit depending on the length of the HF
cable in the vicinity of the microwave probe.
The evaluation unit has to be protected against vibrations. In
some cases, it is advisable to set up the evaluation unit on a
stand separated from the pipeline system.
For instrument installation you should foresee a cutoff device
to allow easy and quick disconnection of the device from the
power supply.
Provide an automatic separating device (line circuit breaker)
that disconnects the unit from power within 0.03 seconds in
case of failure. The separating device must be matched to the
cable cross-section of the supply line, but at least it must be
designed for 1 A continuous current.
When installing the evaluation unit on a crystallizer, use a
distance rail to minimize the thermal radiation and conduc-
tion. See Figure 4-3:
For outdoor applications, the evaluation unit must be pro-
tected from direct sunlight and rain, for example by a suitable
shelter.
