3. Assembly
3.1. Defining the assembly location
If exposed to all weather conditions, we recommend to equip the UV flame
detector with a
Weather protection hood, type: WH d 07, part ID: 80621.
For dimensions and mounting measurements of the UV flame detector, refer to:
Drawing no.: 3.09262.1-1 or 3.09262.10-1
When defining the installation location of the UV flame detector, account for the
visual viewing angle of the device,
vertically / horizontally, it is:
α = 90°
However, the response sensitivity reduces towards the sides.
For this reason, face the UV flame detector directly towards the
object to be monitored.
Because the flame detection depends on the intensity of the flame and its
distance to the UV flame detector, it must be installed as close as possible to
the object to be monitored.
For space monitoring, account for the visual viewing angle of the detector.
If the device is to be installed in outside areas or in roof-covered halls (tank
storage monitoring, gas stations or similar),
please be advised that even such gas flaring flames, gas and welding flames as
well as electric arcs of
electric welding devices and electric railway overhead lines that are far away
can trigger the detector. In cases such as these, it is critical to coordinate the
sensitivity setting of the detector with the plant in advance.
In rooms with a high level of dirt content (dusty atmosphere or with high oil
content), install the UV flame detector so that it is preferably ventilated with fresh
air and so that no oil deposits or dust can form on the viewing pane.
