Differential pressure measuring device |
摘要 |
A differential pressure measuring device of the three diaphragm type is disclosed in which the measuring in diaphragm is isolated from the substance being measured by a pair of sealing diaphragms. The measuring diaphragm is included in a cell assembly that provides overrange protection for the measuring diaphragm and isolation of the measuring diaphragm from the influence of static pressure induced housing strains.
