Calculation of sensitivity for capacitive pressure transducers requires the integration of the deflection function of a clamped‐edge thin diaphragm. For typical square‐formed diaphragms we integrated analytically a closed form deflection function obtained by the Ritz‐method. This exact integration enables fast and accurate simulation.
