Sensor for measuring the presence of precipitation Rain presence sensors are used when it is necessary to discriminate between rainfall and condensation. The measurement principle employed is that of conductivity between two electrodes; these are kept above environmental temperature by heaters in order to prevent condensation.
Highlighs: - Heated sensor for avoiding valse measurement due to dew; - Relay contact when rain starts; - Direct connection to pole 45÷65 mm diameter. Technical file
