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°).
Warning:
With threaded versions, the housing must not be used to screw in the
instrument! Applying tightening forces on the housing can damage its
internal parts.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument 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 outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through 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
flange or the seal surface of the thread.
Information:
If the medium reaches the antenna, buildup can form on it and cause
faulty measurements later on.
