DTT31, DTT35
Please note the following when changing the adapter:
• Use a new O-ring. Diameter 15.54 x 2.62 mm (0.61 x 0.1 in).
EPDM 70 Shore material has FDA 3-A approval.
• Only fix the device (sensor module) in place with an open-ended wrench AF27.
• Screw and unscrew the adapter with an open-ended wrench AF27 or AF32, depending on
the process connection (→ Chap. 7.1.2: 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 regu-
larly 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 you replace the O-ring at the same intervals as you replace the other seals in
your process.
