The rain alarm consists of a sensor model RSG-4 and a signal converter model 8RA-4 and provides a switch-over contact when it rains. The sensor is gold-plated and corrosion resistant. Heating elements in the sensor prevents unintended alarm when there is heavy mist or dew. The sensitivity of the switch-over contact is adjustable on the signal converter. The unit is used to open and close windows or greenhouses.
