Stress reducing stop for unstretched pressure sensing diaphragm

摘要: A sensing cell for pressures which includes a housing and diaphragm that deflects relative to surface under pressure differentials, the movement of is sensed provide indications changes. The has center disc like deflecting portion, an outer peripheral support ring clamped supporting in housing, integral, reduced section web joining portion ring. cross causes act as free edge during deflection. and/or are configured so at near rated overpressure stop means central its annular where joins reduce maximum stress on thus prevent over stressing overpressures, hysteresis innaccuracies.
