The pressure transmitter transmits the pressure of the measured medium to internal sensors (such as diffused silicon or ceramic piezoresistive elements) through a metal diaphragm, while achieving physical isolation to prevent corrosive media from damaging sensitive components. The choice of membrane material directly affects the applicability and lifespan of the transmitter, especially in fields such as food, pharmaceuticals, and chemicals that require high hygiene and corrosion resistance.

Amowellsensor metal diaphragms are precision-engineered components for pressure instruments such as:
* Diaphragm Pressure Gauges
* Pressure Sensors
* Pressure Transmitters
* Pressure Switches
* Diaphragm ValvesThey provide high accuracy, reliability, and corrosion resistance in harsh environments, ensuring stable pressure measurement and long service life.

Materials
We manufacture metal diaphragms using a variety of high-performance alloys:
* Stainless Steel: 304, 304L, 316, 316L
