C-Box (optional)
4.2 Auxiliary
•
Drill Ø 20 mm for steel
•
32 mm wrench for union nut
•
Pliers for circlips (Ø 20 mm) for adjusting the wall thickness at the sensor
4.3 Mounting of the Sensor
The sensor is to be mounted as follows:
•
Determine the place of mounting on the duct. On horizontal or inclined ducts the sensor should be
mounted from top.
•
In case of duct diameters greater than Ø 200 mm or a special application one has to install up to three
sensors which are located 120 mm apart from each other and moved by 120° towards each other.
•
The distances are valid for the vertical and horizontal installation position.
•
Follow the necessary distances of valves, bows, fans or cellular wheel sluices etc. and also other
measurement devices like temperature and pressure etc. to the sensor. (see fig. 4)
Fig 4: Minimal distances of the sensor to duct bends and baffles.
•
With free fall applications (e. g. after screw feeders or rotary valves) a free fall height of at least 300 mm
would be perfect.
