RW-PF

Rain/Wind Sensor

The Rain/Wind Sensor RW-PF measures wind speed and recognizes precipitation. Wind and rain alarm are output via dry contacts and displayed by LEDs on the board of the device. The wind threshold value is set with DIP switches.

  • RW PF (30159) RW PF (30159)
  • Wind measurement: The wind strength measurement takes place electronically and thus noiselessly and reliably, even during hail, snow and sub-zero temperatures. Even turbulent air and anabatic winds in the vicinity of the weather station are recorded
  • Setting of the wind threshold value with DIP switches inside the housing
  • Potential-free output for wind alarm, additional wind alarm LED on the board. Changeover contact can be used as normally open or normally closed contact
  • In case of a malfunction of the wind sensor, wind alarm will be activated and the Power LED in the case will blink. Malfunction will also be triggered if there has been no change of the measured wind value within 48 hours (failure monitoring)
  • Heated precipitation sensor (1.2 watts): No false reports as a result of fog or dew. Dries quickly after precipitation has stopped
  • Potenzial-free output for rain alarm, additional rain alarm LED on the board. Changeover contact can be used as normally open or normally closed contact
