2.1 Two instrument series

The two instrument series are generally identi-

cal in their function and efficiency as well as in
the shape of their antenna systems. However

the housing construction, the materials used

and their electronic construction are different.

An indicating instrument with analogue and
digital indication is optimally mounted in the

sensors of VEGAPULS 81 series.
