Gems Sensors liquid level sensors and switches provide high-reliability monitoring and detection of a wide range of fluid media and applications anywhere from medical reagent level monitoring, to sensing of liquids in food and beverage applications, to hydraulic fluids, to diesel fuel tanks (gas level indicator), to water and wastewater, deionized or potable water, and hundreds more. With a deep portfolio of technology options including reed switch-based floats, solid-state electro-optical, conductivity, capacitive, ultrasonic and guided wave radar, Gems Sensors level sensors and switches can accommodate contact, non-contact and non-intrusive sensing requirements.Learn More About Level Products >

Gems designs and manufactures a complete range of flow sensors and switches for the reliable and effective measurements of both conductive and non-conductive fluids, as well as gases. The complete Gems flow sensing portfolio is designed for versatility and performance. It is organized into five product types: piston, shuttle, paddle, thermal dispersion, and electronic. At preset rates ranging from 50 cc/min to 100 GPM, rugged Gems flow switches will initiate alarm actuation or automatic system shutdown, making them a vital component of any predictive maintenance strategy. They are commonly specified for rotating equipment, conveyors, gas sampling and distilling, water purification systems, welders, semiconductor equipment, chemical processing, machine tool and robotics applications. All flow switches feature high-quality, corrosion-resistant materials with choices ranging from stainless steel to Ryton. Models are offered with fixed or adjustable actuation settings, viscosity compensation or high pressures, media compatibility with slurries and particulates and in-line models and designs to satisfy any mounting or space requirement.Learn More About Flow Products >

Gems offers a wide range of industrial pressure sensors, transducers, and switches. Each is ruggedly designed to address customer measurement challenges in hydraulics and pneumatics; water and wastewater; HVAC; OEM compressors and pumps; refrigeration systems; oil and gas; off-highway; machine tooling; medical gases; in-process control; and other applications. They are also offered in gauge, absolute, differential, vacuum and compound types, and in standard ranges from vacuum to 10,000 psi. High-temperature and submersible versions are also available. The Gems portfolio includes chemical vapor deposition (CVD), sputtered thin film, capacitance, and micromachined silicon (MMS) pressure transducers. These technologies support a diverse range of requirements. Rugged industrial pressure switches from Gems provide basic "On/Off" functionality, either factory set point or adjustable, for a broad range of price and performance compatibility. Depending upon selection, units can offer over 1 million cycles of reliable service. For especially tough environments, Gems further offers a CVD-based solid state pressure switch with a field-proven ASIC design.Learn More About Pressure Products >

Gems Sensors offers a complete range of 2-way normally open/closed, 2-way normally closed, and 3-way directional miniature solenoid valves that are available in general purpose, cryogenic (-320°F) and isolation types. Their rugged construction incorporates a bubble tight plunger for reliable operation over millions of cycles without failure, making them ideal for use within demanding environments. Gems Sensors electromechanical solenoid valves provide 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.Learn More About Solenoid Valve Products >

Temperature sensors and switches are used for the effective protection of internal combustion engines, pumps, compressors, gearboxes, reservoirs, and industrial power plants. For temperature sensing of non-conductive oils and refrigerants, open thermistor sensors are commonly specified. Gems Sensors & Controls designs and manufactures several models of highly rugged temperature switches and open thermistor sensors. Compact, hermetically sealed Gems temperature switches utilize a high-pressure liquid-filled capillary for the effective sensing of temperature changes. As temperature increases, the liquid expands, leading to an increase in capillary pressure. Open thermistor sensors feature a proprietary fused glass hermetic seal, along with an axial feed through design, for exceptional high-pressure and temperature sensing capabilities. Their unique construction allows for the effective monitoring of level and temperature parameters within a single measurement device.Learn More About Temperature Switches & Sensors >

Gems Sensors Electronic Relays are rugged and dependable solid-state relays that provide long service life due to a completely encapsulated construction that are impervious to shock or vibration. Gems Sensors also offers intrinsically safe (IS) relay options (SAFE-PAK®). Gems Sensors Electronic Barriers are passive, energy-limiting devices that provide intrinsically safe DC outputs for a variety of sensors such as level and flow switches, level indication transducers and transmitters, and many others.Learn More About Electronic Relays & Barriers >

Warrick® Conductivity level control systems rely on the liquid level sensing capability of probes (electrodes) that are housed inside fittings designed to accommodate one or more probes. The concept is simple: take advantage of a liquid's conductive properties to complete a circuit and cause a control relay to actuate. These single- or multi-point sensors have no moving parts and the stainless steel corrosion-resistant electrodes can be cut to the desired length. Multiple probes per fitting allow control of several functions in less space with less expense for equipment and installation. To create a system select from numerous level controls, fittings and probe options. For OEM's we also have the capability to custom configure liquid level control sensors and electrode fittings to meet your specific conductivity level control application requirements.Learn More About Warrick Conductivity Controls >
