describe
Diaphragm seal is mainly used to protect the application of pressure measuring instrument in special medium. In the diaphragm measurement system, the diaphragm of diaphragm seal is mainly used to isolate the medium from the instrument.
The filling liquid inside the system conducts the pressure to the measuring instrument.
For the special requirements of customers, we can provide diaphragm seals with different designs, materials and system filling fluids.
For more technical information on diaphragm seals and diaphragm seal systems, refer to IN 0.06, "application, operating guidelines, design.".
Through 990.16 diaphragm seal, PN 400 / 2.500 high pressure application can be realized. With its special design, built-in diaphragm and precise measurement, the product can also be connected with small flange. 990.16 optional flush type joint, flange process edge can be cleaned and flushed as required.
The diaphragm seal can be directly connected to the measuring instrument, and the high temperature application type can be connected through the condensing element or flexible capillary.
For product materials, Wika offers a variety of choices, and the upper chamber and liquid receiving parts of diaphragm seal can be made of the same or different materials. The wetted parts can also be painted.
