Extended Diaphragm Seal Unit Pressure Gauge:
- Extended Diaphragm Seal is mounted on the Nozzle Flange of the Process Pipeline.
- The diaphragm is extended to the process media through the Nozzle.
- The length and Diameter of the extension are decided as per the process requirement and nozzle diameter.
- The diaphragm is directly extended through the Nozzle, preventing clogging or other obstructions in the connection nozzle.
- Extended Diaphragm Seals are Suitable for corrosive, highly viscous, crystallizing, or hot-pressure media.
- Optional features are a cooling Tower, a Capillary for Remote mounting of the Pressure Instrument, and a Stud / Nut and gasket for assembling the Diaphragm Seal with the Process Flange.
