Differential pressure sensing apparatus. |
摘要 |
<p>An apparatus for sensing differential pressures is provided. The apparatus includes a housing having an inner chamber filled with an incompressible working fluid. First and second diaphragms are provided in said housing for interacting with the fluids being measured. A flex-tube is provided in the housing and is coupled to one of the diaphragms for sensing the differential pressure. One end of the flex-tube is securely mounted to the housing and the other end is coupled to the diaphragm. A quartz sensor is positioned on the core for sensing strain applied to the flex-tube by the differential pressure exerted on the diaphragm.</p> |
