Flanged Diaphragm Seal-Extended Type
Product Description
Flanged seals with extended diaphragms isolate pressure gauges from the medium, preventing damage from corrosive, viscous, or toxic media.
The extended diaphragm seal design makes it suitable for thick-walled vessels, insulated pipes, or containers, effectively avoiding measurement interference caused by insulation or vessel wall thickness.
