3.4 Installation
3.4.1 Installation instructions
!
Note!
•
Select a measuring point where representative measurement can be taken.
Do not mount the sensor where medium flow is turbulent and fast-flowing.
•
We recommend you to fit the transmitter with a weather protection cover
(see Accessories
→
Chap. 9).
•
Attach the sensor to a special extension tube. Due to the weight of the sensor
(approx. 5 kg), the sensor cable does not provide sufficient support.
Never carry the sensor by its cable.
•
The best fixture is a damping support which holds the sensor vibration-free.
•
Install the system at an easily accessible position to prevent danger arising for the
operating personnel (during commissioning or when carrying out maintenance and
cleaning work).
•
Route all cable connections to prevent mechanical damage and interference from
other lines.
•
Install measuring channels in the direction of flow to obtain a self-cleaning effect.
•
The activated sludge version of the sensor is equipped with a cleaning unit which
prevents soiling or blocking due to particles by compressed air. For other applications
with soiling contents, the cleaning unit is available as an accessory.
•
Install the air outflow of the cleaning unit at the narrow side of the light slit.
3.5 Post-installation check
•
After mounting, check that all connections are secure and leak-tight.
•
Check that the sensor is secured such that it is free of vibration and tension.
•
Check whether all cables have been routed without damage or electromagnetic
interference.
