Sensor Diaphragms for Pressure Measurement and Isolation

Sensor diaphragms are precision elastic components used in pressure sensors, transmitters, and mechanical pressure gauges. Depending on the application, they function either as the primary pressure-sensitive element or as an isolation barrier between the measured medium and the sensing element.

Their mechanical properties—such as linearity, repeatability, surface flatness, and internal stress—have a direct impact on measurement accuracy and long-term stability. Sensor diaphragms are widely used in industrial instrumentation, process control, and MEMS-based pressure sensor designs.
