Metal membranes are the thin circular plates. For transducers and pressure transmitters, it is
assumed that the membrane is loaded with uniform load over the entire surface. In case that the membrane is
rigid over the edge, then it is called a diaphragm. In general, the membranes are divided into flat and
corrugated. Corrugated diaphragms can resist much higher pressure than flat diaphragms and they are used
mainly in the low pressure area. In contact with various aggressive fluids, membranes are most commonly
made of high alloy austenitic steel, which have high corrosion resistance, have good spring properties and
they are stable at different temperatures. The deflection analyses of corrugated diaphragms are very important
in sensitivity of transducers/transmitters. The application of corrugated diaphragms gives possibility to control
sensitivity of thin diaphragms by geometrical parameters. In this paper numerical and experimental structural
analysis of a thin corrugated dia...phragm 19 mm diameter, with variable material thickness and corrugation
number is presented. Experimental tests are conducted on a corrugated stainless steel (AISI 316) diaphragm.
The measured deflections are compared with numerical results in ANSYS software package. The results
showed small deviations between numerical and experimental data, which is very important for further
diaphragm application of measurement instruments.
