Rain Detector DRD11A

Vaisala DRD11A Rain Detector

Rain Detector DRD11A

Rain and snow are quickly and accurately detected with the DRD11A rain detector. It operates via droplet detection rather than by signal level threshold. A special delay circuitry allows about two-minute interval between raindrops before assuming an OFF (no rain) position. This enables the sensor to accurately distinguish between rain cessation and light rain.

Key Benefits

An internal heating element
Ensures that the detection surface dries quickly. An essential factor in calculating intensity.
A special delay circuitry
Allows about two-minute interval between raindrops before assuming an OFF (no rain) position.
Reliable droplet detection
Sensor performance is not affected by reasonable amounts of dirt and dust.
