Our stainless steel diaphragms are engineered specifically for use in pressure sensors and transmitters, offering high sensitivity, chemical resistance, and excellent fatigue performance. Fabricated using 316L or other corrosion-resistant stainless steels, these diaphragms ensure stable and accurate readings in harsh industrial environments.
With advanced welding, polishing, and shaping techniques, each diaphragm provides consistent thickness and deflection control. Whether for fluid pressure sensing, gas applications, or sealed instrumentation systems, our sensor diaphragms are the ideal choice for OEMs and instrument manufacturers requiring precision and reliability.

Specification note: We can custom-manufacture metal diaphragms of any size and material, as well as strip stock for stamped diaphragms, to meet your requirements.
*Corrugated diaphragm is a type of thin-shell elastic element. The diaphragm is a circular, membrane-shaped, flexible sensing component. When different pressures (or forces) are applied to both sides of the diaphragm, it deforms toward the side with lower pressure, causing its center to produce a displacement that corresponds proportionally to the pressure difference.
Due to the large number of interrelated parameters, the design of a corrugated diaphragm is quite complex. In most displacement-based instruments and meters, the diaphragm is required to produce an elastic displacement that is at least on the same order of magnitude as its thickness. The diaphragm thickness is selected based on the magnitude of the applied pressure.
