Please note the following when changing the adapter:
• Use a new O-ring. Diameter 15.54 x 2.62 mm (0.612" x 0.103").
EPDM 70 Shore FDA 3-A approved.
• Fix the device (sensor module) in place with an open-ended wrench AF 27. Never hold the
housing of the device to loosen or tighten the process connection adapter.
• The adapter can be screwed on with an open-ended wrench AF 27 or AF 32, depending on
the process connection, (see section 6.1.2 adapter versions).
The maximum torque is 80 Nm. The thread can become loose if exposed to severe strain
through pressure and temperature. For this reason, the air-tightness must be checked
regularly and the thread tightened if necessary.
• When changing the adapter, make sure that the sensor tube of the sensor is not damaged.
!
Note!
We recommend to change the O-ring in the same time frame as of all other sealings in your
process.
