RAIN DETECTOR HD 2013.2

Foto prodotto
ZOOM 		The HD2013.2 is a rain detector based on the capacity principle. The capacity value of the sensitive element, on an alumina rest, changes according to the surface dampened by raindrops. An integrated heater keeps it dry, evaporates water and prevents false signals caused by fog or dew. The heater also activates at low temperatures, melting the snow and allowing to detect snow precipitations.

Typical Applications:
The rain detector can be used either as a separate device, or connected to a data logger system (for example: in a weather station).
