DANGER!
Danger to life from explosion
Through working in flammable atmospheres, there is a risk of explosion
EN
which can cause death.
▶
In hazardous areas, only use instruments that are approved for those hazardous areas.
WARNING!
Temperature load
When mounting the pressure gauge, care should be taken that the permis-
sible operating temperature of the measuring instrument is maintained,
considering the effects of convection and thermal radiation!
▶ Thus the pressure gauge and the shut-off valve must be protected by suffi-
ciently long measuring lines or syphons.
▶ The influence of temperature on the indication and measurement accuracy
must be observed. The effective maximum surface temperature is not only
dependant upon these instruments, but mainly on the respective medium
temperature! With gaseous substances, the temperature may increase as a
result of compression warming.
▶
In these cases it may be necessary to throttle the rate of change of pressure
or reduce the permissible medium temperature.
Observe the special conditions (see chapter 4 "Special conditions for safe use
(X conditions)").

Only carry out set-up work in non-hazardous environments.
