Pressure gauges are DNV-certified
November 2007
Pressure Measurement & Control
Det Norske Veritas (DNV) is a world-wide, leading classification society. Classification is a system for safeguarding life, property and the environment at sea. It entails verification against a set of requirements during design, construction and operation of ships and offshore units. These requirements are based on the accumulated experience from DNV's large classed fleet, research and development and more than 140 years of experience.
The series D4, D7 and D8 Afriso-Euro-Index Bourdon tube pressure gauges for chemical applications now come with DNV certificates. This means they are approved for application on DNV-certified ships, speedboats and oil platforms and can be used in all DNV-certified offshore areas.
The sturdy Bourdon tube pressure gauges for chemical applications are designed for pressure measurement of gaseous and liquid media in rough and aggressive environments. The ranges reach from -1-0 bar to 0-1600 bar (accuracy class 1.0). The pressure gauges are suitable for ambient temperatures from -20°C to +60°C and media temperatures up to +150°C. The housings are made of stainless steel 1.4301 and have a pressure relief port. The pressure gauges can be made to customer specifications with various housing diameters, bottom or back connection, glycerine or silicone filling, different types of fastening and special scales. Some versions are available with electrical contacts for switching and control tasks.
These pressure gauges for chemical applications are not only suitable for naval and offshore applications, but are also just as appropriate for use in the chemical industry, in machine building and in process and environmental technology applications.
