Hail sensor
The HDI is a very low-power, maintenance-free, totally sealed and mechanically ultra-robust acoustic instrument with no mobile parts.
It is able to detect hailstones between 0.5 and 7.5 cm diameter and will survive the most extreme hail episodes.
The sensing part of the instrument is a three layer polished stainless disc supported by an unbreakable stainless-steel arm. Impacts of hailstones (or any other lithometeors in the same range of kinetic energy) induce a measurable change in internal acoustic pressure.
It features continuous or pulse analog voltage outputs and supports SDI-12 communication, serial RS- 232, 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.
