Viscosity Management in Group B, C and D Hazardous Locations
Posted on Fri, Sep 30, 2011
Boston—Cambridge viscometers can now be used in Gas Group B hazardous locations in addition to Group C and D hazardous environments. This ex
tension of approvals to Class 1, Division 1, Groups B, C, and D applies to the entire family of in-line 300-series sensors made by Cambridge Viscosity. These are the primary sensors used in refining, exploration, petrochemical and chemical processes, including both standard and high temperature sensors.
The new Gas Group B classification enables these sensors to be used in hazardous locations, which include hydrogen, fuel and combustible process gases containing more than 30% hydrogen by volume or gases of equivalent hazard. Groups C and D include environments that may contain carbon monoxide, ether and hydrogen sulfide, or for Group D, gasoline, acetone, ammonia, benzene, butane, natural gas, propane and other gases of equivalent hazard.
“We are pleased that our 300 sensors have been approved for Gas Group B use. Our sensors have been Group C and D classified for years, but being approved for the more stringent hydrogen environments allows us to provide viscosity management solutions to a whole new segment of customers,” says Cambridge Director of Engineering Daniel Airey.
Cambridge 300 sensors are used in a wide variety of industries for in-line and in-tank applications. Cambridge’s viscometers are well suited to the rigors of harsh environments due to their robust, durable design and construction.
