hygienic design, e.g. surface roughnesses of parts that come into contact with media
Ra ≤ 0.8 μm.
Note:
The distances are the same for sensors with remote amplier.
The drainability of the tank and coupling must not be hindered by installation of the
measurement probe.
When installing the measurement probe in a coupling, it must be ensured that the
distance between the probe and coupling wall is greater than the length of the coupling
(maximum length L <= (D-d))
In the case of installation in a tank, it must be ensured that the cleaning tting is posi-
tioned in such a way that both the connection and the sensor can be completely wetted
and cleaned.
When using hygienic process adapters, the notes “17 Accessories” are to be observed
(insert note).

Centering: To prevent contact between the probe and the bypass pipe during oscilla-
tions, the probe should be centered according to its length and depending on the diam-
eter of the bypass pipe. To do this, it is necessary to insert one or two centering pieces,
see “17 Accessories”.
Tank welds can aect the measurement accuracy.
