Industrial diaphragms convert pressure to power or pressure to electrical signals in sensors that monitor dynamic conditions such as mass flow rate, volumetric flow rate, and density.
The most sophisticated diaphragms are fabric-reinforced and three-dimensional in design, where coated fabric will not suffice. In these designs, STERN EWS substrates are heat-formed into complex shapes and then compression molded with elastomers on one or both sides. In such molding operations, control of the permeability of the fabric is critical to ensure optimal penetration and bonding of the elastomer to the fabric substrate.
In medical devices, STERN EWS fabrics are used in fabric reinforced to control air or blood flow rates. In aircraft engines, STERN EWS fabrics are used in fuel flow control systems to optimize performance, and in natural gas pipelines to meter the flow rates.
