►

Tighten the sensor with a spanner

until you can feel the end stop�

You can replace the Viton O-ring (B)

by the supplied EPDM O-ring�







A = rotatable housing

Adapters G ¾ ensure that the sensor can be connected to different process

connections� The adapters have to be ordered separately as accessories�

►

Mount the adapter (D) to the

sensor�

►

Fix adapter by means

of a coupling nut, a clamp flange

or similar (C) to the process
