RHD-Rain Sensor:
Extremely robust and reliable acoustic rain sensor
The RHD is a low-cost, high-precision, and ultra-robust rain sensor. It features very low power consumption, is maintenance-free, and has a completely sealed acoustic detector with no moving parts. The sensing device is a polished stainless steel hemisphere supported by a strong stainless steel arm. It detects changes in the acoustic pressure that are induced by the impact of raindrops or hailstones. The RHD also includes a distrometer that returns the drop size distribution.
It features continuous or pulse analog voltage outputs and supports SDI-12 communication, serial RS232, and Modbus RTU RS485 (using an optional adapter). The full configuration of the sensor can be customized at any time with a Plug-and-Play PC connection or remotely, using serial commands.
The RHD sensor is a low-cost, high precision, ultrarobust rain gauge instrument.
It is a very low-power, maintenance-free and totally sealed acoustic instrument with no mobile parts. The sensing part of the instrument is a polished stainless steel hemisphere supported by a strong stainless steel arm.
The impact of heavy precipitation or hail on the leading edge of wind power turbine blades can reduce the life time of the blade extremely.
Main factors to damage the leading edge are: Speed of the blade, Rain intensity, Droplet size of Rain or Hail.
In order to reduce the erosion of the leading edge of the blade, and save money in the long run, it is important to monitor the precipitation and the droplet size, so the blade can be controlled if necessary.
Fields of application
With its distrometer and hail detection functions, the RHD is a valuable instrument for soil erosion forecasting and precipitation monitoring in agriculture. As this sensor is maintenance-free, it is also suitable for remote weather stations (on and offshore) and scientific research.
