Abstract
A pressure variation monitoring device adapted to measure pressure variation of an object is disclosed. The monitoring device includes an abutting device adapted to detect the pressure variation of the object to be detected to generate a displacement in response to the pressure variation; a magnet supported on the abutting device to be movable therewith in response to the pressure variation; a coil co-axially surrounding the magnet and allowing the magnet to be movable relative thereto; an oscillation circuit, coupled to the coil to generate an oscillation signal; a signal processing unit for receiving and processing the oscillation signal to provide an output signal; and a display for providing a reading of the pressure variation.
