Features
SS404 series flush mount pressure sensor is ideal for process media that can clog standard instrument connections—the front flush-type diaphragm sealing permits cleaning of the process connections without residues. The parts in contact with the fluid in S.S. 316L are fully welded. The sensor covers a range from 0.35 to 600 bar gauge or absolute. You can configure with custom outputs and pressure interfaces upon request.
SS404 series is a stainless steel isolated pressure sensor with double sealing. The “Positive Sealing” holds a second sealing in the upper part of the connection, ensuring an outstanding level of safety in case the first sealing fails and preventing the leaking of the process fluid.
