The Chemical and Petrochemical Industry makes extremely high demands on all instruments used within the industry process. But most pressure instruments can only be made from a limited number of materials. BKW through its diaphragm seal facility can supply over 50 different materials of construction from Tantalum, Monel, Hastelloy through to exotics such as Gold, Silver, Platinum, Zirconium and Titanium. Likewise, for our temperature products, we can manufacture thermowells from over 11 exotic materials all with coded welding certification. Through our partners we have all the major approvals required throughout the world covering ATEX, FM, GL, GOST etc.
