Diaphragm Materials Guide for Pressure Transmitters
In modern industrial processes, especially in chemical, food, and pharmaceutical industries, corrosion remains one of the most critical challenges affecting pressure measurement reliability. Among all components, the diaphragm material plays a decisive role. It directly contacts the process medium and determines whether a pressure transmitter can maintain accuracy, stability, and long service life. This guide introduces commonly used diaphragm materials and their typical applications, helping engineers make more informed decisions. 316L Stainless Steel – The Industry Standard 316L stainless steel is one of the most widely used diaphragm materials due to its excellent corrosion resistance and good processability. Its low carbon content...
