► Screw the sensor into the adapter (G)
until it is hand-tight. When doing so,
avoid mechanical effects on the sealing
areas, the hygienic area and the pressure measuring cell..
► Make sure that the O-ring (H) is correctly
positioned.
I
► Clamp the sensor + adapter into a
lamping device (I). Tighten the clamping
device only slightly so that the adapter
does not warp.
► Tighten the sensor using a spanner until
you can feel the end stop (this corresponds to a maximum tightening torque
of 35 Nm). Note: Further tightening may
affect the sealing effect.
► Insert the unit in a universal process connection RD52.
► Tighten the coupling nut.
