To maintain the housing protection, make sure that the housing lid is
closed during operation and locked, if necessary.
Make sure that the degree of contamination specified in chapter
"Technical data" meets the existing ambient conditions.
On devices with a threaded fitting, the hexagon on the process fitting
must be tightened with a suitable wrench.
See chapter "Dimensions" for wrench size.
Warning:
The housing or the electrical connection may not be used for screw-
ing in! Tightening can cause damage, e. g. to the rotation mechanism
of the housing.
If there is strong vibration at the mounting location, the instrument
version with external housing should be used. See chapter "External
housing".
The permissible process pressure range is stated on the type label.
The instrument should only be operated with these pressures if the
mounting accessory used also fulfils these values. This should be en-
sured by suitable flanges, welded sockets, tension rings with Clamp
connections, sealings, etc.
Higher process temperatures often mean also higher ambient
temperatures. Make sure that the upper temperature limits stated in
chapter "Technical data" for the environment of the electronics hous-
ing and connection cable are not exceeded.
