   An attempt is made to determine dynamic rigidity of bellows and membranes used as detector elements for pressure sensors. The results of experimental studies of characteristics defining dynamic rigidity of these elements obtained under different conditions are offered. A special-purpose stand is designed to perform the studies. The questions of determination of hydrodynamic factors required to calculate dynamic characteristics of elastic detector elements are considered.
