 Precipitation
Detector Model 6420-A
Product Description
The Model 6420-A Precipitation Detector utilizes a gold-plated grid to sense
the occurrence of precipitation. The water completes a circuit within the
detector, and the resulting signal energizes a relay. The relay closure can
be used to sound alarms, close doors, or input into data acquisition systems.
When precipitation ends, two cartridge heaters dry the grid, and the circuit
to the relay is broken.
All electronics are solid-state, and are sealed in a weatherproof enclosure.
The sensor is oriented on an angle to allow water to drain off. A wind screen
conserves sensor heat and thus reduces power consumption. AC power is required.
Two U-bolts are included for easy mounting of the 6420-A.
