Apparatus for measuring differential pressure in air blower

摘要

The present invention relates to an apparatus for measuring a differential pressure in an air blower, comprising: a bell mouth provided with an inlet for introducing air into the air blower; a differential pressure cover coupled to the bell mouth for transmitting an inlet pressure change through a tube; and a differential pressure measuring unit for detecting the inlet pressure change transmitted through the tube. According to the present invention, a differential pressure is measured in an intake port side of the air blower in which an air flow is most stable, while keeping the apparatus from acting as an air flow resistor so as to prevent the occurrence of turbulence, thereby allowing an accurate measurement of the differential pressure.
