Precipitation Analyzer
Part number: 5.4107.xx.xxx
-
The Precipitation Analyzer can be used to reliably detect supercooled precipitation and reliably assess the associated freezing situation.
The following precipitation types are measured:
• Freezing drizzle (FZDZ)
• Freezing rain (FZRA)
• Subcooled water on the sensor
• Ice
• Spray
• Rain
• Sleet
Precipitation analysis perfected: Precipitation Analyzer.
Our cutting edge technology detects and measures different precipitation types, especially supercooled precipitation. Thanks to the unique design with a pyramid-shaped measuring surface made of special ceramic material and resistant glass coating, we detect precise surface temperatures.
The sensor uses as measurement principles the analysis of temperature peaks to detect the heat of crystallization and the different dielectric properties of water and ice. This enables very accurate discrimination and quantification of precipitation incidents, including phase changes.
The analyzer is ideal for early warning systems in traffic applications, on roads, bridges, airports, marine and industrial applications where icing poses a safety risk.
With its advanced method for early detection of supercooled precipitation, the device contributes to efficient winter maintenance and timely initiation of safety measures. The device was developed and tested with the German Weather Service (DWD) for use at airports.
