The rain and moisture evaluation instrument AR-1 with rain and condensation sensor FR-1 is a universal measuring system to detect rain, snow, condensation, moisture, strong dew to control illumination, light, jalousies, marquees, blinds, shutters, air conditioning, heaters, ventilation, flaps, roof hatches and build-ups.
Rain / moisture etc. (yes/no) is indicated by LED (no value over time).
As output is a relay, with potential-free changeover contact (no/nc).
The maintenance-free and weather-proofed (IP67) rain sensor FR-1 has an integrated heating. It is powered by the rain evaluation instrument AR-1.
During no indication of rain / condensation, the sensor heating is in stand-by mode, to save energy and extend life time.
