➀ Sensor module with adapter thread
➁ Standard O-ring
➂ Adapter
Please note the following when changing the adapter:
• Use a new O-ring. Diameter 15.54 (0.61 in) x 2.62 mm (0.1 in).
With either EPDM 70 Shore FDA or FKM 70 Shore material.
• The device (sensor module) can be fixed in place with an open-ended wrench AF 27mm.
• The adapter can be screwed on with an open-ended wrench AF 28mm or AF 32mm
(depending on the process connection).
The maximum torque is 80 Nm (59 lbs ft). 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 process isolating diaphragm of the sensor is
not damaged.
!
Note! O-ring change:
We recommend to change the O-ring in the same time frame as of all other sealings in your
process.
