Abstract

PURPOSE: To ensure an accurate detection for beginning of the rainfall, especially for the first one or two drops of the rain by using the sensor plate containing the conductor provided on the insulated plate.
CONSTITUTION: Sensor plate 2 provided at outdoor detection part 1 has conductor 4a and 4b featuring the comb-line, spiral and other forms provided on insulated plate 3. And heater 5 is inserted into plate 2 to dry plate 2 wetted by the rain. When the rain begins to fall and the first one or two drops fall on plate 2, conductor 4a and 4b are short-circuited to deliver the rainfall signal from plate 2. This signal is amplified and then delivered through output terminal 14 in the form of the drive signal. This drive signal opens and closes the door of the astronomical observatory dome or lights up alarm lamp 10 to inform the start of the rainfall.
