Sommer - Model HDI -Acoustic Hail Sensor
Extremely robust and reliable acoustic hail sensor. The HDI sensor measures the impact of individual hailstones on a stainless-steel disc using a special acoustic detector, signal processing and calculation. The sensing surface is a 200 mm diameter omnidirectional head, containing the electronics of the system. The HDI can detect hailstones between 0.5 and 7.5 cm and up to 25 hits per second. Comparable to so-called disdrometry, it can distinguish between 15 size-classes. The size distribution is reported as percentage of all detected impacts according to classification table.
Hail sensor HDI
The hail sensor HDI is shipped with a robust, stainless steel mounting arm. With the included USB-converter the sensor can be directly connected to a PC and configured for your needs.
The HDI is the sensor of choice wherever damage by hail is of concern: farming on fields and in greenhouses, infrastructure like facades, roofs and soloar panels or vehicles.
