The history of Gems Sensors & Controls began 60 years ago in 1955, when the founder of the company, Edward H. Moore, developed the first level indicator and then, together with Gordon Seigle, founded Gems Company (GS from Gordon Seigle and EM from Ed Moore). The company's first commercial success brought the bilge level gauge to the shipbuilding industry. The success of the company's shipping and industrial products has led to the rapid expansion of Gems' manufacturing and office space in Connecticut, USA.
Today Gems designs and manufactures a wide range of liquid level sensors, flow and pressure switches, transmitters and transducers, miniature solenoid valves, and pre-assembled liquid handling systems. The company has manufacturing facilities in North America, Europe and Asia, and has sales and product support offices around the world.
Gems level sensors provide reliable level monitoring of a wide variety of liquids such as oils, hydraulic fluids, fuels, waste water, drinking water and others. Effective measurement is ensured by the use of a wide range of contact and non-contact sensors using magnets, reed switches, floats, electrical and optical technologies, conductivity sensors, capacitive, ultrasonic and piezo-resonance sensors. Several liquid level detection technologies can be used in one measuring device. The product catalog contains single point and multipoint sensors, continuous level measuring devices, pressure sensors, coolant level sensor and visual level indicators.
Liquid flow sensors and switches provide efficient measurement of conductive and non-conductive liquids and gases. The relays have a wide range of controlled flow rates and provide alarms or automatic system shutdowns. Electronic flow switches are supplemented with visual indication of current indicators. The model range includes devices with fixed or adjustable response parameters, viscosity or high pressure compensation, operating in the presence of sludge and solid particles in the flow.
Industrial pressure transmitters, transducers and relays provide the measurements required by the consumer in hydraulics and pneumatics. Industrial pressure transmitters provide continuous real-time monitoring and can be used over a wide temperature range. Available options for pressure switch and sensor housings made of aluminum, stainless steel, brass, plastic, galvanized steel.
Miniature solenoid valves provide efficient automatic control of liquid, vapor or gas flows. Gems designs and manufactures a complete line of 2-position and 3-position solenoid valves for general purpose and cryogenic (down to -320 ° F) versions. Gems Sensors & Controls products are widely used in the medical device industry, food industry, automotive industry, water, oil and gas transportation systems, chemical industry, ventilation and air conditioning, semiconductor manufacturing, and various pneumatic systems.
