More than 60 Years in Fluidic Systems

The Gems Sensors & Controls was founded in 1955 when the company founder, Edward H. Moore, developed a level indicator in his basement and patented in 1959. Along with an associate, Gordon Seigle, he established the Gems Company, deriving the name from the initials of the founders. First commercial success came from a bilge switch for the small boating industry. The rapid acceptance of Gems’ products for marine and industrial applications led to a continual expansion of facilities and staff – from a 6,500 square-foot building to a facility of 60,000 square foot in Plainville, Connecticut, USA. Today, Gems Sensors & Controls has manufacturing facilities in North America, Europe, and Asia and supports sales, engineering and service offices around the world. As a division of the Fortive Corporation, a fortune 500 company with a presence around the globe, Gems has the resources to support your design and manufacturing requirements anywhere you call home.
