Abstract. Dynamic and static errors of the membrane sensitive elements of control systems under complex mechanical and thermal influences are analyzed. The strain called the membrane element stroke is taken for the unified parameter accounting for interconnection between aerodynamic, hydraulic, mechanical, and thermodynamic complex effects. Mathematical models allowing calculation of the static and dynamic errors of the membrane sensing element of control systems exposed to various mechanical and thermal influences are constructed. The developed approach has been used in designing of several magnetic contacts with increased reliability and improved performance applied in burglar and fire alarm systems.
Keywords: membrane sensing element, linear deformation, angular deformation, static error, dynamic error, move sensitive membrane element, integrated effect, reed switches
