Required tool: SW 24 open-ended spanner
WARNING!
Prior to commissioning, the pressure sensor must be subjected to a visual inspection.
Only use the pressure sensor if it is in perfect condition with respect to safety.
Making the mechanical connection
To ensure that the wetted parts do not get soiled, the protection cap should not
■
be removed until immediately prior to mounting.
Use only BAM-certified gaskets.
■
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 pressure sensor to the prescribed torque via
■
the spanner-flats, and using tools which are appropriate and clean for use with
oxygen.
The correct torque depends on the dimensions of the process connection and
the gasket used (form/material). When screwing in or unscrewing the pressure
sensor, do not use the housing or plug for purchase.
When screwing in, do not cross the threads.
■
Only lubricate thread with materials approved for use with oxygen.
