gems sensors controls

Gems sensors specializes in a broad range of instrumentation used in level, pressure and flow. Gems has become a leader in providing high quality controls and has done so since 1950. Their history has allowed them to grow and become a world wide provider with manufacturing facilities in the United States, Europe and Asia


A visible level gauge that is a safe alternative to cloudy, breakable sight glasses. High Visibility - Brilliantly colored flags are easy to read, even at great distances. The water level indicator is isolated from the measure media; therefore, Suresite® water level gauges can be used where sight glasses are not even a consideration. Durability - Stainless steel, PVC, CPVC, PVDF, Hastelloy or other exotic housings, whatever the media requirements, provide years of maintenance-free service.

Flow Switches

Gems line of flow switches feature a broad range of configurations for use in liquids or gases. At preset rates, ranging from 50 cc/min to 100 GPM, Gems switches will initiate alarm actuation or automatic shut-down of a system. Switch types include: Piston, Shuttle, Paddle & non-moving part type switches.

Point Level

Custom length float level switches are extremely versatile. Custom length levels can be configured with "up to seven" independent switch actuation levels, depending on the series type. These "multi-station" units offer the most practical way to monitor multiple liquid level points within a single tank. Only a single entry point into the tank is required, and all electrical wiring emanates from a single source. In addition to tracking changing level points of a single liquid within a tank, "multi-station" float level switches are ideal for monitoring liquid interfaces and emulsions in vessels simultaneously containing two or more liquids. Contact Gems with your liquid specifications for further information on this type of application.

Continuous Level

A wide variety of material combinations provide compatibility for most liquid media. Gems XM- & XT-800 Series provide solutions for most small to mid-size tanks in both process and OEM applications; for deeper tanks (to 18 feet) look to the Gems 36000 and 66000 Series.

Pressure Switches

Gems offers a choice of pressure switches, water pressure switches from compact cylindrical models for OEM use, to larger, enclosed units for rugged process applications. These water pressure switches are ideal for the filtering process of coolants in the machine tool industry, use in transmissions of off-highway vehicles and as redundant systems with

Pressure Transducers

From vacuum to 10,000 psig (-1 to 689 bar), we've got you covered with the industry's largest selection and best choice of pressure transducer technologies. Our capacitance type sensors are ideal for high volume use; sputtered thin film types are the most precise pressure sensors you can buy, and our other types satisfy all requirements in between

Solenoid Valves

Electromechanical solenoid valves provide effective automatic fluid flow control of liquid or gas, as well as air, water, or steam. They are widely specified within medical equipment, food processing, industrial, automotive, water transfer systems, oil and gas, analytical instrumentation, clinical chemistry, HVAC, printing, environmental test chamber, semiconductor manufacturing, and larger pneumatic valve control applications.

Controls and Gems understand that not every application is a “one part fits all” situation. For specialized products or OEM’s we are here to help find solutions to your problems.
