Part number: 5.4110.10.xxx
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
