The lter element is integrated in the process assembly. It is located in

a rotatable metal ring and has the following function:

•

Atmospheric pressure compensation (with relative pressure meas-

uring ranges)

Turn the metal ring in such a way that the lter element points down-

ward after installtion of the instrument. This provides better protection
