DEVICE FOR DETECTING SALT CONCENTRATION OF AIR AND A DEVICE FOR CONTROLLING AN INTAKE AND AN EXHAUST OF A DISTRIBUTING BOARD USING THE SAME, CAPABLE OF MINIMIZING DAMAGE CAUSED BY SALT EXISTED IN ELECTRICAL PARTS

摘要

PURPOSE: A device for detecting salt concentration of air and a device for controlling an intake and an exhaust of a distributing board using the same are provided to remarkably extend lifetime by protecting various kinds of electronic products and machines from damage caused by salt and to prevent the frequent replacement of parts, thereby remarkably reducing costs for the replacement and maintenance.;CONSTITUTION: A device for detecting salt concentration of air comprises a high voltage generator(11), a trigger sensor(2) for detecting the salt concentration, and a signal amplifier(13). The high voltage generator generates high voltage required for driving the trigger sensor. The trigger sensor for detecting the salt concentration discharges when the salt concentration of the air is over the set concentration while in the state receiving high voltage generated in the high voltage generator. The signal amplifier amplifies discharge signals when the discharge signals are generated by the trigger sensor.;COPYRIGHT KIPO 2013;[Reference numerals] (11) High voltage generator
