APPARATUS FOR MEASURING DROPPING DISTANCE OF NONCONTACT PISTON OF POISE PRESSURE GAUGE

摘要

PURPOSE: An apparatus for measuring dropping distance of noncontact piston of poise pressure gauge is provided to accurately measure a real moving distance of a piston by sensing a position movement of a core ring and displaying a current position, a dropping rate and a dropping distance on a digital display. CONSTITUTION: A pressure adjusting device(2) in which a handle(2a) is installed is formed to a face of one side of a frame(1). A poise providing bell(3) in which a cylinder and a piston are inserted is formed to one side of a upper surface of the frame(1). A certain number of poises(4) are formed on a peripheral surface of the poise providing bell(3). A measuring object pressure gauge(5) is coupled on a pressure gauge installing nipple(6) in the other side of the upper surface of the frame(1). A core ring(10) is inserted into a peripheral surface of a piston(9). A coil(13) having primary and secondary coils is installed on an inner circumference of a supporting nut(12). A display(15) is installed to an upper surface of one side of the frame(1).
