3.2 Intended use
The pressure gauges in DirectDrive design should be used exclusively for measuring
static pressures in dry, gaseous, not highly viscous and non-crystallising media that will
not attack copper alloy parts. The process connection and the measuring line must be
dry and free from foreign bodies. Avoid rapid and frequent load cycles.
The scope of application is defined by the technical performance limits and materials.
The pressure gauges have been designed for industrial applications in indoor and
outdoor areas. This instrument is no "safety accessory".
