Abstract
A gauging system includes a source of pressurized fluid, one or more fluid outlet means, each including a fluid line connecting the source of pressurized fluid with a fluid orifice that is located to measure small gaps and distances between the elements of a machine or die, and one or more pressure transducers connected to measure the pressure in each fluid line. One or more adjustable valves are provided between the source of pressurized fluid and each fluid line. A computer measures the transducer output to determine the distance between mold elements. The valve or valves include a threaded male member having an inlet at one end and a frustoconical surface with openings passing through it at the other, and a threaded female member having a channel in one end and an outlet in the other joined by another frustoconical surface. The male member may be screwed into the channel of the female member to control the distance between the two frustoconical surfaces and thus the fluid flow from the inlet to the outlet through the openings. The system is calibrated by measuring the transducer output for a set of distances including the open mold distance, with an essentially infinite hose len…
