3.2 Intended use
The mechanical pressure measuring instruments in DirectDrive design should be used
exclusively for measuring static pressures in dry, gaseous, not highly viscous and non-crys-
tallising media that will not attack copper alloy parts. The process connection and the
measuring line must be dry and free from foreign bodies.
The scope of application is defined by the technical performance limits and materials.
The pressure measuring instruments have been designed for industrial applications in
indoor and outdoor areas.
Improper use is defined as any application that exceeds the technical performance limits or
is not compatible with the materials. Checking against improper use is the responsibility of
the operator.
