DRAPER, Utah, Dec. 13, 2012 /PRNewswire/ -- Flexpoint Sensor Systems, Inc. (OTCBB: FLXT) today announced that it has completed development, passed all testing and received all required internal and external certifications, including UL certification, for a sensor that is integrated into a pressure relief device. Now that UL certification has been received, the device is being sold and distributed by them. The companies are also currently progressing on two other similar products. Flexpoint has been working for over two years on these products and gains a crucial foothold in the industrial safety market with the completion of this product. Current estimates put the size of the industrial safety market in the US at well past the $100 million mark. The initial production order of approximately 1,000 units has been delivered. It is expected that initial annual volumes will be approximately 6,000 – 10,000 units and expand as product acceptance occurs. Flexpoint's partner for the application is a specialized manufacturing and distribution company that specializes in, and is a leading producer and marketer of, these types of devices. Development, testing and certification of the product have taken place over a two year period. Our partner is a leading provider of pressure relief devices that protect vessels or systems from over-pressurization. Flexpoint is working closely with our partner on a joint press release to provide more specific details. Pressure relief devices are designed to fail at a predetermined pressure or temperature to protect the rest of the equipment from failing. Pressure relief devices are commonly used in aerospace, aviation, defense, medical, railroad, nuclear, chemical and oilfield applications. They can be used as single protection devices or as a backup device for a conventional safety valve; if the pressure or temperature increases and the safety valve fails to operate (or can't relieve enough pressure fast enough), the device will activate.
