7.5.4 Determine probe length L for coaxial probes
►
Measure the exact total length L
K
of the coaxial pipe (Fig. 7-9, on the right).
► Deduct 9 mm from the total length of the coaxial pipe: L
K
– 9 mm = L.
►
Note down L. It is needed for setting the device parameters
7.6 Installation of the unit with single probe
Before installing and removing the unit: Make sure that no pressure is
applied to the system and that there is no medium in the tank that could
leak. Also always take into account the potential dangers related to extreme
machine and medium temperatures.
For installation in closed metal tanks, the tank lid serves as a launching plate R
(Fig. 7-10, Fig. 7-12). Notes
Options are as follows:
• Installation to G¾ process connection directly in the tank lid
• Installation in the tank lid using a flange plate (e.g. for tanks with thin walls)
During installation of the process connection on the tank lid observe the
subsequent orientation of the housing (display orientation, cable outlet).
The sensor housing cannot be rotated with respect to the internal thread!
Subsequent alignment of the sensor housing is therefore not possible.
Furthermore, installation in open tanks
possible
