American Sensor Technologies, Inc. (AST) has obtained 79/2009/EC approval for two pressure ranges of its AST Model AST2000 and Model AST4000 OEM pressure sensors. The approval is a necessary European Community Directive for components and systems intended for installation on hydrogen-powered vehicles.

American Sensor Technologies, Inc. (http://www.astsensors.com) has obtained 79/2009/EC approval for two pressure ranges of its AST Model AST2000 and Model AST4000 OEM pressure sensors. The approval is a necessary European Community Directive for components and systems intended for installation on hydrogen-powered vehicles.

“This approval allows AST to serve the growing market of hydrogen powered vehicles. We are the only EC79 approved sensor supplier in the world.” - Karmjit Sidhu, Vice President Business Development and AST Co-Founder

The 79/2009/EC approval was obtained for the 2MPa range of the Model AST2000 and Model AST4000 pressure sensors that are used as components on the vehicle hydrogen regulator controlling hydrogen flow to the fuel cell stack. Also approved are the 35MPa range of pressure sensors that are typically used on Class 3 hydrogen tanks for use on buses, forklifts, cars, farm machinery, off-road vehicles and stationary back-up power systems.

To obtain approvals, AST pressure sensors were tested according to Regulation EU 406/2010 to verify compliance with Regulation EC 79/2009 of the European Parliament and the Council of the European Union (see http://eurlex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2009:035:0032:0046:en:PDF). The requirements and test procedures were established to meet integrated system safety requirements. With greater world emphasis on green technology and sustainability, hydrogen is highly considered an alternate clean fuel carrier for powering surface transportation.
