20140196537 | INTEGRATED MEASURING APPARATUS FOR MEASURING VAPOR PRESSURE AND LIQUID LEVEL OF LIQUID TANK - A technique for measuring vapor pressure and liquid level of a volatile liquid contained in a tank. An integrated measuring apparatus sequentially measures vapor pressure and differential pressure by use of a single pressure sensor and a switching valve which switches between paths for measurement of the vapor pressure and the differential pressure. In addition, the integrated measuring apparatus includes a pressure sensor configured to sequentially measure vapor pressure and total pressure or the combination of the vapor pressure and liquid pressure; and a switching valve configured to be connected to a vapor pressure tube and a liquid pressure tube and switch between connection paths with at least one input port of the pressure sensor, wherein the vapor pressure tube is connected to an upper part of the tank and the liquid pressure tube is connected to a lower part of the tank. | 07-17-2014 |
20140190237 | OUTPUT SPECIFICATION CALIBRATING APPARATUS FOR CAPACITIVE PRESSURE SENSOR - An output specification calibrating apparatus for a capacitive pressure sensor. The output specification calibrating apparatus enables adjustment of non-linearity, offset, and gain of the capacitive pressure sensor in a software manner at the time of shipment. Accordingly, it is feasible to easily adjust output specifications of the capacitive pressure sensor and to thereby meet various needs of customers. | 07-10-2014 |
