The measuring receiver transmits the values measured for amount and intensity of precipitation. Depending on the maximum possible intensity, either drops are counted or the turnovers of a tipping bucket are counted or a combination of both these measuring principles is employed.

- pulse output
- with intensity-dependent linearization
Instrument serves as sensor for quantity and intensity of precipitation, for the digital transmission of measuring values.

- pulse output
- with intensity-dependent linearization
This precipitation transmitter has an additional heating for the casing, and is therefore wellsuited particularly for the use in mountains.

- analogue output
- pulse output
- with intensity-dependent linearization
Instrument serves as sensor for quantity and intensity of precipitation, for the analogue transmission of measuring values.

with Datalogger DL 1/N The instruments serve for the measurement of the precipitation falling on the ground surface.

The impulses from the Ombrometer or Precipitation Transmitters are totalled in accordance with the coded measuring range and converted into a current and/or voltage signal.

The Laser Precipitation Monitor serves as measuring value transmitter, and is well-suited for the measurement and detection of different types of precipitation such as,
• drizzle
• rain
• hail
• snow
• and mixed precipitation.

The following additional sensors can be connected to this model:
• temperature
• rel. humidity
• wind speed
• wind direction

The instrument is designed to detect the beginning and the end of precipitation. It can be used for status report, or as signal transmitter for the control of rain protection devices, such as windows, awnings, or Venetian blinds.

Instrument serves for determination of the instantaneous precipitation intensity. Herefrom, control- and warning signals can be derived.

The instrument is designed for electrical acquisition of start and end of precipitation. The precipitation drops are detected by a sensor area, and with wetting a contact is closed.

For the power supply of wind speed transmitters or wind directions transmitters The in- and outputs are each protected by fuses. The housing is made of plastic fibre. Suitable for: Wind transmitter type:
• Compact
• Classic

The Datalogger is used to store and record the pulse from a Precipitation Transmitter with a Reed-contact. The precipitation is measured by a tipping bucket with a Reed-contact output.

For the protection of the Datalogger DL 1/N from direct rain. Complete with mast clamp 1 1/2".

Protection against bird droppings for the collecting funnels of the above precipitation recorders. Refuses birds on the edge of the collecting funnel

Power supply unit to provide power to the heating of the preceding precipitation recorder.

Is put into the collecting funnel of the Precipitation Meter or Rain and Snow Meter in order to avoid losses caused by snow vorticities.

for 5.4000... / 5.4001... acc. to DIN 58667 B

Protection against bird drop- pings for the collecting funnels of the Ombrometer (5.4031.11/31/51...). Refuses birds on the edge of the collecting funnel.

Used to collect non-turbulent precipitation in wind conditions. Suitable for the preceding Ombrometer and Precipitation Transmitter.

For the power supply of wind speed transmitters, wind directions transmitters or combined instruments. The in- and outputs are each protected by fuses.

For the power supply of wind speed transmitters, wind direction transmitters or combined instruments. With integrated terminal strip for the connection and distribution of the cables. The in- and outputs are each protected by fuses. The housing is made of plastic fibre.

Used to mount the preceding Ombrometer, resp. Precipitation Transmitter. The collecting area can be elevated to a height of 1; 1.2 or 1.5 m. (5.4031.11/31/51...). Refuses birds on the edge of the collecting funnel.

For the vibration-reduced operation of the LPM on an available concrete foundation, provided by the customer.

The program serves for the communication of a PC with the Thies Dataloggers DL1/N., DL 15, and TDL 14 via serial interface.

• PC-Program LPM View • communication • visualization • filing The program LPM serves for the display of data, which are induced by the LPM. The program can file the data sent by the LPM as well as represent them in graphic form. Thanks toa user-friendly surface design it is possible to analyse each record, sent by the LPM, in a very simple way.
