WIKA DSS Diaphragm Seal Instruments are rugged pressure assemblies engineered to protect vital gauges and transmitters from the harshest environments in the chemical, petrochemical, oil & gas, and process industries. By isolating delicate measuring components from aggressive, viscous, contaminated, or extreme-temperature media, these systems prevent clogging and resist corrosive attack. Available in both compact threaded connections and heavy-duty flanged configurations, the robust, leak-free construction of the DSS portfolio provides installation flexibility while acting as a critical containment barrier against hazardous or toxic fugitive emissions.
