5.1 Mechanical mounting

Prior to commissioning, the gas density sensor must be subjected to a visual inspection.
Leaking fluid is indicative of damage.
■
Only use the gas density sensor if it is in perfect condition with respect to safety.
■

5.1.1 Requirements for mounting point

The mounting point must meet the following conditions:
Sealing faces are clean and undamaged.
■
Sufficient space for a safe electrical installation.
■
Protected from weather influences. Permanent exposure to UV light/sunlight can lead
■
to a change in the colour of the plastic parts.
Under corrosive environmental conditions (such as salty, humid air), reductions in
■
the gloss level of the metal surfaces, or even corrosion on the instrument, may occur,
which make readability of the product label more difficult.
For information on tapped holes and welding sockets, see Technical information IN
■
00.14 at www.wika.com.
Permissible ambient and medium temperatures remain within the performance
■
limits. Consider possible restrictions on the ambient temperature range caused
by mating connector used.

5.1.2 Installation using an adapter and measuring chambers

WARNING!
Physical injury and/or damage to property due to the selection of
the wrong instrument version
▶
Before installation, commissioning and operation, ensure that
the appropriate gas density sensor has been selected in terms of
measuring range, design and specific measuring conditions.
The measuring location should preferably be positioned directly at the gas
compartment. The measurement at the end of measuring lines prevents
optimal results (unwanted temperature differences to the main tank).
CAUTION!
If model GD-20 is delivered with an adapter or measuring chamber, it
is completely mounted and tested for leak tightness in our company.
Dismounting compromises the leak tightness of the measuring assembly
and renders it unserviceable!
▶
The process connections of the available adapters and/or measuring
chambers are to be properly sealed and connected to the measuring
location.
