4 Mounting
4.1 General instructions
Select an installation position you can easily reach for
mounting and connecting as well as later retrofitting of an
indicating and adjustment module. The housing can be rotated
by 330° without the use of any tools. You can also install the
indicating and adjustment module in four different positions
(each displaced by 90°).
Use the recommended cable (see chapter "Connecting to
power supply") and thighten the cable gland.
You can give your OPTISOUND 3030 C additional protection
against moisture penetration by leading the connection cable
downward in front of the cable entry. Rain and condensation
water can thus drain off. This applies mainly to mounting
outdoors, in areas where moisture is expected (e.g. by
cleaning processes) or on cooled or heated vessels.
Fig. 2: Measures against moisture penetration
The reference plane for the measuring range is the lower edge
of the transducer.
Make sure that a min. distance - the so called dead zone -
below the reference plane is maintained in which a measure-
ment is not possible. The exact value of the dead zone is
stated in the Technical data in the Supplement.
