GHM HD 2013.2 RAIN DETECTOR


Price:

Description

The GHM 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. The instrument external circular dome acts as a windshield for the sensor, preventing false indications. The instrument is equipped with three different outputs: a “Rain ON/OFF” output, which detects whether it is raining/ snowing (ON) or not (OFF), also used to control a relay coil or similar devices; a 0…1V voltage analogue output (calibrated) and a 1,5…6KHz frequency output (not calibrated), which provide an accurate indication of current precipitation intensity.
