SYSTEM FOR CHECKING FILTER OF AIR CLEANER FOR AUTOMOBILES

摘要

PURPOSE: A system for sensing a time to replace an air cleaner filter is provided for drivers to confirm the time to replace the filter through a gauge while driving. CONSTITUTION: A system for sensing a time to replace an air cleaner filter comprises a power unit, a pressure sensor(1), a converter(2), a processor(3), and a display unit. The power unit supplies power to the system. The pressure sensor is installed in a discharge port connected to a filter unit, and measures the pressure of a filter. The converter converts a measured value into the pre-set form. The processor controls a measurement period of the pressure sensor. The processor receives a converted measured value, and compares the value with a pre-set standard value. The display unit displays the time to replace the filter.
