3.2 Intended use

These instruments are used to control process values and to monitor plants in industrial
applications. The contact pressure gauge, with up to 3 integrated model 831 inductive
contacts, displays the process pressure on site and opens/closes circuits at defined
pressure values.
The instrument offers many application possibilities for gaseous and liquid aggressive media
that are not highly viscous or crystallising.
Only use the instrument in applications that lie within its technical performance limits (e.g.
temperature limits, material compatibility, ...).
→ For performance limits see chapter 9 "Specifications".
The instrument has been designed and built solely for the intended use described here, and
may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on operation contrary to
the intended use.
