Laser Precipitation Monitor
Part number: 5.4110.00.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 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.
