Abstract: The present disclosure provides a food processor, including: a cup body; a cup cover detachably connected to an upper end of the cup body, the cup cover including a pumping opening communicating with an inner cavity of the cup body, and being provided with a cover handle; and a vacuum pumping device detachably connected to the cup cover, the vacuum pumping device including a pumping hole and an exhaust hole, the pumping hole being configured to communicate with the pumping opening after the vacuum pumping device is mounted on the cup cover. The food processor has a simplified vacuum pumping structure, improving the use convenience of the food processor.

Abstract: The present disclosure is provided with a measuring element (M) and a measuring device. The measuring element includes a base body, a diaphragm and a permeation resistant layer, the diaphragm is fixedly connected to the base body, with a sealed cavity being defined between the diaphragm and the base body. The permeation resistant layer is arranged on an inner side surface, facing the sealed cavity, of the diaphragm, and extended continuously on the inner side surface of the diaphragm at least beyond a connection region of the diaphragm with the base body. The measuring device includes the measuring element (M).

Abstract: A process diaphragm seal includes a seal body, a diaphragm, and a ring member. The seal body includes a flange that surrounds a cavity. The diaphragm includes an active portion that extends over the cavity and a peripheral portion that surrounds the active portion. The ring member clamps the peripheral portion of the diaphragm to an outer wall of the flange through an interference fit between an inner wall of the ring member and the outer wall of the flange. A seal is formed between the peripheral portion of the diaphragm and the outer wall of the flange.

Abstract: A process pressure transmitter system includes a process pressure transmitter housing and a process pressure sensor in the process pressure transmitter housing. A metal flange is configured to mount to a process vessel which carries a process fluid. An isolation diaphragm attaches to the metal flange and is exposed to the process fluid through an opening in the process vessel. The isolation diaphragm comprises a polymer diaphragm bonded to a metal face of the metal flange. A capillary passageway carries a fill fluid from the isolation diaphragm to thereby convey a process pressure to the pressure sensor.
