Diaphragm seal 990.10
Diaphragm seals are used to protect pressure measuring instruments in applications with difficult applications. In diaphragm seal systems, the diaphragm affects the separation of the instrument and the medium. The pressure is transmitted to the measuring device through the filling liquid of the system, which is inside the sealing diaphragm system.
A wide range of designs, materials and filled system fluids are available to fulfill customer-requested applications. Seal Diaphragm model 990.10 with threaded connection in screw design is suitable for various application areas. It is possible to change the lower body without changing the diaphragm seal system.
By using this flood diaphragm, it can cover high pressure up to 250 bar. It is possible to install the diaphragm seal to the measuring instrument through direct connection, for high temperatures through a cooling element or through a flexible capillary.
WIKA offers a variety of solutions for material selection, where the upper part of the flood diaphragm and wetted parts can be made of the same or different materials. Wet parts, as an alternative, can be covered.
aplications:
- For destructive, hot, corrosive and toxic environments
- Industrial processes
WIKA diaphragm seals (often also called chemical seals), installed with pressure gauges, process transmitters, pressure switches, etc., are internationally recognized and valued for the most demanding measurement tasks. be. By using a flood diaphragm, measuring instruments can be used in extreme temperatures from -90 to +400 degrees Celsius and with destructive, corrosive, heterogeneous, abrasive, highly viscous or toxic materials. Optimum material-specific flood diaphragm designs are available for each application.
