Abstract: Disclosed is a contactless mass measuring device for measuring current values consumed when the displacement of a levitation member is corrected depending on the load applied in a magnetic levitated contactless state and converting the current values to mass. The present invention comprises: the levitation member having a cross-shaped cross section; a pair of permanent magnets of which one is installed on the top of a vertical part and the other is separated therefrom so that the levitation member can be levitated; horizontal electromagnets for radially supplying suction force from the axial center of the vertical part to guide the levitation member; an axis sensor for detecting whether or not the center of the vertical part matches with the center of the horizontal electromagnets; and ring-shaped vertical electromagnets for supplying the suction force in the vertical direction of a horizontal part to control the vertical position of the levitation member; a height sensor for detecting whether or not the horizontal part is positioned at the center between the vertical electromagnets; a control part connected to the height sensor to output the current to the vertical electromagnets so that the horizontal part can be returned to the original position when not positioned at the center between the vertical electromagnets; and a calculation part for measuring the current values outputted from the control part through a current sensor and converting the current values to the mass of a sample.

Abstract: The present invention relates to a non-invasive pressure measuring apparatus which measures a current value used in compensating for a gap according to the pressure inside a tube which is included in the inner side in order to convert pressure. A non-invasive pressure measuring apparatus prepared thereby has a cross section bent in a “C” shape in order to accommodate a tube for passing a fluid inside, and comprises an elastic plate which has a slit formed on one side thereof and has magnetism; a coil which is wound in a longitudinal direction of the elastic plate; a width detecting sensor which detects the gap of the slit; a control unit which is connected to the width detecting sensor and outputs current to the coil in order to be restored to the original position when the gap of the slit is widened; and a calculation unit which measures the outputted current value from the control unit and converts the pressure of the fluid inside the tube.
