Barometer (on Hub PCB)
The Barometer device is maintenance-free, however, if required observe the
following with regard to the central Hub box screw cap Gore-Tex
®
filter.
Pressure Sensor Filter Replacement:
There is a small venting filter for the pressure sensor of the MetPak Base Station
located on the 'Hub' box lid which ensures proper conditions are present in the
MetPak Base Station 'hub' box for pressure measurements without allowing any
moisture or other damaging pollutants into the box. This filter is made from Gore-
Tex
®
material and is designed to last a long time without replacement, however,
Gill do recommend that this filter is replaced every 24 months to ensure proper
operation of the pressure sensor and to keep the electronics inside the 'hub' box
dry.
If you do not replace the filter every 24 months you may start to see elevated or
erroneous readings of the pressure sensor with time and this behaviour can be
corrected by replacement of the Gore-Tex
®
filter unit.
The Gore-Tex
®
filter kit is available from:-
Gill Instruments
Part Number
1723-PK-024.
To replace the filter, unscrew the 4 screws retaining the hub box lid. Remove the
existing Gore-Tex filter and M12 Nut. Fit and secure the new filter with the nut
provided. Re-fit the 4 lid screws.
Should you be uncertain as to how often you should be replacing the filters for your
application or if you wish to discuss this in more detail please contact Gill support
and we will be able to provide a recommendation for you.
Returning the MetPak Base Station
If the unit has to be returned, it should be carefully packed in the original packaging
and returned to your authorised Gill distributor, with a full description of the fault
condition. An RMA number should be obtained from Gill Instruments first if
returning directly to Gill Instruments.
