Abstract
PURPOSE: To enable the measurement with good characteristics, by giving the specified relation among the linearity of pressure sensor, linearity of pressure-volume conversion element, pressure volume constant, and pressure volume constant of seal diaphragm.
CONSTITUTION: The high-pressure side seal disphragm 1A and the low-pressure side seal diaphragm 1B deliver the pressure from the liquid contact section to the center diaphragm 3. The center diaphragm 3 is deformed with the differential pressure between the high and low pressure sides, and this is detected by the pressure sensor 5. When the linearity NLP of the pressure sensor, the linearity NLc of center diaphragm, pressure volume constant Pvfc of center diaphragm, and pressure volume constant Pvfs of seal diaphragm are selected as the relation of equation shown in Figure, the linearity of the difference measuring device of two liquid chambers using the pressure sensor can be increased, enabling highly accurate measurement.
