Differential pressure measurement cell with two membranes - has flexural element with fluid connection to transfer vol. region via gap designed for ignition and combustion safety
The differential pressure measurement cell has two membranes (2,3) between which are one or more fluid-filled transfer chambers. Two transfer vol. regions (4,5) lie adjacent to the facing sides of the membranes. A signal line (10) is fed to a flexural element (11) mounted in a space (23) between the membranes with a fluid connection to at least one of the transfer vol. regions. The fluid connection is made via a gap (27) whose width to length ratio does not exceed a value required for ignition and combustion safety. ADVANTAGE - For inflammable or explosive materials. Compact with simple design which achieves ignition and combustion safety.
