The sensor is a low-power, maintenance-free, and fully sealed acoustic instrument with no moving parts. Its sensing unit features a triple-layer polished stainless steel disk mounted on a robust stainless steel crossarm. Hail impacts on the disk induce internal acoustic pressure variations. The instrument incorporates a dedicated analog conditioning module and digital I/O module, supporting:
Analog voltage output
SDI-12 communication
TTL communication
RS-232 communication
RS-485 communication
Typical application scenarios include:
Meteorology (hail/solid precipitation): High-resolution hail monitoring and early warning systems
Marine/offshore: Wind turbine arrays and buoy monitoring
Infrastructure: Road, railway, and airport protection systems
Agriculture/land management: Crop protection and research
Scientific research: Precipitation studies
