The Gems Sensors & Controls (Gems) story began 60 years ago in 1955 when the company founder, Edward H. Moore, developed a level indicator in his basement. It was patented in 1959. Along with an associate, Gordon Seigle, he established the Gems Company (GS for Gordon Seigle, EM for Ed Moore).

Gems' first commercial success was a bilge switch for the small boating industry. Rapid acceptance of Gems' products for marine and industrial applications led to continual expansion of facilities and staff - from a 6,500 sq. ft. building to a facility of 60,000 sq. ft. in Plainville, Connecticut, USA.

Today, Gems designs and manufactures a broad portfolio of liquid level, flow switches and pressure switches, sensors and transducers, miniature solenoid valves, and pre-assembled fluidic systems. Gems is a division of Danaher Corporation, a fortune 500 company with a presence around the globe. Gems Sensors & Controls has manufacturing facilities in North America, Europe, and Asia and supports sales, engineering and service offices around the world. Gems has the resources to support your design and manufacturing requirements anywhere you call home.
