DIAPHRAGM SEAL CASE STUDY Diaphragm seals, also known as chemical seals, isolate pressure-measuring instruments from the process media. The system pressure is transmitted to fill fluid through the diaphragm seal, and from there to the pressure-measuring instrument itself. Choosing the right diaphragm seal depends […]
Badotherm offers a full welded construction on their diaphragm seal systems. A full welded system means that not only the capillaries are welded to the diaphragm seal body, which is standard practice, but also the capillary is welded with a special construction and special weld […]
In many industries it is required to have a ‘plastic’ or polymer coating over the diaphragm seals or wetted parts of the diaphragm seals in order to protect your instruments. Badotherm offers a wide range of polymer coatings on their diaphragm seals. Polymer coating are […]
It remains a beautiful picture… a DP Level measurement with a Yokogawa pressure transmitter type EJX110A and Badotherm USL type diaphragm seals. This is a heavy duty execution with a 2” class 900-1500 RJF process connection according the ASME B16.5. The USL diaphragm seal type […]
After our introduction of the Badotherm HTDS up to 600°C process temperature, our R&D did not stop pushing the limits. Again we found a solution to increase the limits of pressure measurements at high process temperatures. Our experience with our HTDS design gave us the […]
Diaphragm seals can consist heavy flanges and are sometimes hard to handle. As such, we developed a simple accessory to facilitate easier handling of these heavy seals: lifting handles. We recommend to use these handles from class 600 and above for size 2” and 3”. […]
