  • Page 6: Mode Of Operation Of The Laser Precipition Monitor

    3 Mode of Operation of the Laser Precipition Monitor A laser-optical beaming source (laser diode and optics) produces a parallel light-beam (infrared, 785 nm, not visible). A photo diode with a lens is situated on the receiver side in order to measure the optical intensity by transforming it into an electrical signal.

    Figure 3 :Schematic Block Diagram 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.
  • Page 9: Figure 4: Side View

    Attention: Do not look into the invisible laser beam! In case the laser caution labels on the housing are not legible any more the sensor must not be operated! Even with a longer exposure time the intensity of the invisible laser beam is considered as safe for the human eye (without using optical instruments).

  • Page 12: Heating

    4.1 Heating All sensor variants have heated glass panes on both heads to prevent interferences through freeze up, steaming up or similar. The heating power is controlled in subject to the ambient conditions. The heating current are measured for self diagnostic and could be read through the diagnostics command (“DD”, only available with PCB Rev.B, see Figure 6).
  • Page 13: Installation

    5 Installation Attention: The instrument must be mounted and wired only by a qualified expert, who knows and observes the generalities of technics, and applicable regulations and norms. Attention: Do not look into the invisible laser beam! In case the laser caution labels on the housing are not legible any more the sensor must not be operated! Even with a longer exposure time the intensity of the invisible laser beam is considered as safe for the human eye (without using optical...

    should be mount with a distance of at least 1m on the same mast. The side distance to other objects should be greater than 2m. We recommend to operate the Laser Precipitation Monitor in an enclosed area for human safety, although the intensity of the invisible laser beam is considered as safe for the human eye (without using optical instruments, Laser Class 1M according to EN 60825-1:1994 A2:2001).

  • Page 16: Mounting Angle

    5.2.2 Mounting Angle First, the mounting angle (with or without housing) should be fastened at the mast. Because of the shading effect of the mast the angle is to be mounted at the highest possible place. Align the angle to the south acc. to Figure 10 (± 10°, Northern hemisphere), and fasten it at the top of the mast. It is advisable to have a second person holding the Laser Precipitation Monitor during the mounting.

    The cables are guided through the respective cable gland to the sensor connecting terminals (Figure 6 or Figure 7), see also wiring diagram (CH. 9). They are connected by means of the respective tension clamp technique. For the orange-coloured connecting terminals put a commercially available screw-driver with a blade width of up to 2mm resp.
  • Page 20: Electrical Installation Via Connector

    5.3.1.1 Electrical Installation via Connector Instruments equipped with connectors, have pre-assembled flange plugs, which are integrated at the housing. The flange plug for the supply with pre-assembled cable has a ferrite sleeve which is already affixed at the cable (between plug and pc-board) against the wall by cable connector. 5.3.2 Closing the Instrument Cover Lift up the housing cover carefully, and take care that no cable is jammed between cover and housing.
