Laser Precipitation Monitor
Part number: 5.4110.10.xxx
-
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 acquisition comprises the types of precipitation, intensity and the spectrum. All measuring values are available for the user via an RS485/422 interface. In addition, the instrument is equipped with two further digital outputs (opto-couplers), which output, for ex., pulses and state of precipitation. The optical components are equipped with an integrated heating.
Suitable Transmitters:
Hygro-Thermotransmitter 1.1005.54.000
Wind Transmitter 4.3519.00.000
Wind Direction Transmitter 4.3129.00.000
