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.

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.
→ For performance limits see chapter 9 "Specifications"
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).
