Active diaphragm seal assembly for pressure measurement

A fluid filled pressure measurement system having a pressure sensor or pressure gauge and a diaphragm seal to a process wherein the diaphragm seal is moveable by changing the volume behind the diaphragm seal by the volume member. In a first position the diaphragm seal is seated or is a parked position such that the diaphragm seal is fixed to avoid deformations during cleaning. 种流体填充压力测量系统具有压力传感器或压力仪表和过程的隔膜密封件，其中，隔膜密封件通过由体积构件改变在隔膜密封件后面的体积可移动。在第位置，隔膜密封件就位或在停止位置，使得隔膜密封件被固定，以在清洁期间避免变形。
