WIKA's diaphragm seal systems are pressure measurement assemblies that combine a diaphragm seal with a pressure gauge, transmitter, sensor, or switch. The diaphragm separates the measuring instrument from the process medium, while a system fill fluid hydraulically transmits the pressure to the instrument. This makes the systems well suited to demanding applications involving aggressive, corrosive, abrasive, viscous, crystallising, toxic, or high-temperature media. WIKA offers a wide range of configurations, including different process connections, wetted materials, mounting methods, and fill fluids, enabling systems to be tailored for chemical, pharmaceutical, biotechnology, food and beverage, and other process-industry applications.
