Rain intensity measurement with processing unit
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.
