DESCRIBE

For mounting to Bourdon tube pressure gauges, pressure sensors or pressure switches. For rotating, polluting and abrasive suspensions under high pressure. It is specially used for pressure measurement of waste water, sludge, concrete, plaster and minerals. Diaphragm seals are used to protect pressure measuring instruments from hazardous media in applications. In the diaphragm sealing system, the diaphragm separates the instrument from the medium. The pressure is transmitted to the measuring equipment through the filling fluid in the system. H21 type diaphragm seal is equipped with threaded joint box and flat embedded diaphragm, which is widely used. Although compact in shape, the product can be used in high-pressure working conditions. In addition, the diaphragm seal can also choose a sanitary design and an optional protective cover. Diaphragm seals and measuring instruments can be assembled directly, or for high temperature applications through cooling elements or flexible capillaries.
