Extended type diaphragm seals are typically used at thick-walled or insulated locations in pipelines and vessel construction. The extended diaphragm ensures a flush measurement and avoid any dead spaces. In these situations, the flush measurement provides a more accurate and direct measurement than standard blind flanged diaphragm seal.
The EXTended diaphragm seal can be provided in many different exotic materials, where diaphragm and wetted parts materials are all made from the same material.
The picture shows a nice example of 550mm long EXT being manufactured in our product facility in the Netherlands.
