How leak-tight a measuring instrument needs to be depends on the application and its conditions. They provide the specifications for the permissible leakage rate, the pressure level and the leak detection methods.
Depending on the application and process medium, WIKA can offer several solutions to ensure the desired internal leak tightness. They range from waterproof versions for standard applications to gas-tight versions to avoid fugitive emissions. In addition to individual products such as instrumentation valves and pressure gauges, there are also ready-to-install solutions that are also gas-tight and tested in accordance with the relevant industry standards.
