Module and high temperature resistant pressure pressure difference transmitter are kept apart to pressure pressure difference transmitter

The utility model relates to a module and high temperature resistant pressure pressure difference transmitter are kept apart to pressure pressure difference transmitter. It includes to keep apart the module: corrugated diaphragm, ripple flange, capillary and fill and irritate liquid, wherein the corrugated diaphragm welding is in ripple flange bottom, it is deep that ripple flange upper portion is followed to the capillary the ripple flange, the capillary with the intercommunication passageway has between the corrugated diaphragm, fill and irritate liquid and be full of capillary and intercommunication passageway. The changer of using this module can realize the liquid sodium of high temperature and press the force measurement, and for sodium -Cooled fast reactor and test circuit provide ressure measurement means, wherein the pressure pressure difference transmitter structure of keeping apart the module has realized high temperature and corrosive isolation, self heating device has realized preventing the sodi
