MWF requires for correct functioning a metallic plate at the process
connection (near Reference point
[R]
).
Material
Hood
PVC, RAL 7001
Storm tape EDPM, weather-resisting
For protection against influence of weather the use of the weather
protection hood SH is recommended. It protects the sensor electronic
against overheating caused by direct solar radiation and avoids
condensation inside of the housing.
Use for mounting in open or non-metallic silos or bins the flange
F2
(F100) made of Aluminium or stainless steel.
Protection against influence of weather
Instead of the flange a metal sheet with
Ø
>150 mm could be used as
well.
Mounting in open or non-metallic silos or bins
The reference point
[R]
is located above the flange.

Screw the bush of the probe on the thread of the feed-through.
- MWF has to be mounted into empty silos or vessels in order to
make sure that wire rope probe hang vertically and don´t knot.
- Use for handling and wearing of the MWF the hexagon or the lower
section of the housing.
18. Preparation of mounting
In most cases the MWF is delivered completely preassembled.
- Do not turn the counter nut against the plastic of the feed-through.
This would result in permanently damaging of the sensor.

After the bush of the probe has been completely screwed, it has
to be secured with the counter nut.
If the device should be delivered with a detached probe, it has to be
attached at the thread of feed-through before mounting the device:
- Do not lift or handle MWF by its probe.
19. Mounting
- Select the mounting position according to the guidelines in chapter
16 and consider the installation advises in chapter 17.
- Screw the MWF into a screw socket or a flange with internal thread.
- Seal the process connection professional.
For most applications a sealing ring is part of the shipment.
- Do not screw in MWF by its housing. Use the hexagon at the
process connection.
Consider the process conditions like e.g.:
temperature, pressure and the characteristics of the process.
