5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: -40 ... +85 °C [-40 ... +185 °F]
■
Humidity: 45 ... 75 % relative humidity (no condensation)
■
WARNING!
Before storing the pressure sensor (following operation), remove any residual media. This
is of particular importance if the medium is hazardous to health, e.g. caustic, toxic, carcino-
genic, radioactive, etc.

6. Commissioning, operation

CAUTION!
Prior to commissioning, the pressure sensor must be subjected to a visual inspection.
Check the diaphragm for any visible damage, since this is a safety-relevant component.
■
Leaking fluid is indicative of damage.
■
Only use the pressure sensor if it is in perfect condition with respect to safety.
■
6.1 Making the mechanical connection
Required tool: Open-ended spanner (spanner width 27 or 41)
With flush process connections, remove the protection cap not until shortly
■
before mounting. During installation, ensure that the diaphragm is not damaged.
During mounting, make sure that the sealing faces at the pressure sensor
■
and the measuring point are clean and undamaged.
Only ever screw in, or unscrew, the instrument via the spanner flats. Never
■
use the case as a working surface.
The correct torque depends on the dimensions of the process connection
■
and the sealing used (form/material).
When screwing in, avoid any jamming of the threads.
