5.5 Protective cover
5.5.1 Function ventilation diaphragm
The ventilation diaphragm enables the relative pressure measurement since
barometric and temperature-dependent pressure fluctuations between the
measuring cell and the environment are compensated for�
The ventilation diaphragm is protected against damage by a screwed cap with
circumferential ports�
For a correct functioning of the diaphragm please take the following into
account:
►
Remove soiling and cleaning agents immediately using plenty of lime-
deficient splash water�
If the sensor is in a cooling stage:
►
Avoid contact of the diaphragm with liquids:
> Avoids negative pressure in the measuring system resulting in a slightly
falsified measured value and additional strain on the diaphragm�
5.5.2 Orientation of the filter cover
The filter cover is freely rotatable around the sensor's axis and thus adaptable to
the environmental conditions�
When the sensor is mounted in a vertical position, the condensate escapes
through the ports in the protective cap due to gravity�
When the sensor is mounted in a horizontal position or similar, the filter protection
cap must be rotated towards one of the two lateral faces to bring the GORE
diaphragm into a vertical position� This guarantees the optimum drainage for
liquids�
