Fig. 11: Changing the adapter
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 x 2.62 mm (0.61 x 0.10 in.) with either EPDM 70 Shore
FDA or FKM 70 Shore FDA material
• The sensor can be mounted with a 27 mm open-ended wrench.
• The adapter can be threaded on and tightened with a 28 or 32 mm (1.1 or 1.26 in.)
open-ended wrench (depending on the process connection).
The maximum torque is 80 N•m. The adapter can become loose if exposed to severe strain
through pressure and temperature. For this reason, the adapter connection must be checked
regularly and the tightened if necessary. We recommend using Teflon
TM
tape as an
additional thread seal.
• When changing the adapter, take care to not damage the diaphragm of the pressure sensing
element.
