In explanation of the construction, and the basic function the block diagram
Figure 3) shows
schematically the most important functional connections (variant “Extended Heating” not shown).
4 Construction of the Measuring Instrument
The Laser Precipitation Monitor consists of the following: a varnished aluminium housing, protection
IP 65, a laser head ( anodised aluminium), fixed at the housing cover, a receiver head (anodised
aluminium) fastened by means of carrier arms (see also
Figure 4 and Figure 5)
The aluminium housing contains the electronics with all necessary interfaces. Furthermore, the
electronics is equipped with light diodes (LED’s), which facilitate an easy and efficient check resp.
diagnosis of the sensor even without serial data connection (
Figure 6 or Figure 7 . In the chapter
“Maintenance” (see Ch. 6 ) you find a functional description of the LED’s.
The replaceable laser head consists of a laser driver circuit board (incl. laser diode), a rectangular
window for the beam forming, a lens and a heated glass pane. The electrical connection to the
electronics is carried out by a 10-pole ribbon flat cable leading to the “Connector Laser”.
The receiver head consists of a receiving circuit board with photo diode and electronics, a lens and
a heated glass pane. The electrical connection is done by a 6-pole ribbon flat cable leading to the
“Connector Receiver”.
