Gems Sensors & Controls has designed and manufactured a broad range of liquid level, flow and pressure sensors, switches, miniature solenoid valves, and preassembled fluidic systems.

LIQUID LEVEL

Gems liquid level sensors and switches provide high-reliability monitoring and detection of a wide range of fluid media. Requirements can range anywhere from the sensing of cooking oil, to hydraulic fluids, to diesel fuel tanks (gas level indicator), to water and wastewater, to biohazards, to even deionized or potable water.To effectively address such a wide variety of measurement challenges, Gems offers a broad range of contact, non-contact, and non-intrusive liquid level sensors and switches. These are available in multiple technology types, including magnetic reed switch-based floats, solid-state electro-optical, conductivity, capacitive, ultrasonic, and piezo-resonant. Multiple liquid level sensing technologies may also be incorporated within a single application. Sometimes, more than one “best fit” solution may also exist, with the ultimate decision simply a matter of customer preference. Products include:

Most Gems standard catalog products can be easily modified with alternate connectors and housings. Or, a custom solution can also be developed, many times delivered in OEM volumes with shorter lead times than most industry off-the-shelf solutions.Detailed specifications on Gems liquid level sensors and switches are available from your Carotek application specialist.

FLOW

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. 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. Products include:

FLOW SENSORS

RotorFlow SensorsTurbine Flow Sensors - Low Flow MeterThe complete Gems flow sensing portfolio is designed for versatility and performance. It is organized into five product types. Piston types are designed for low flow rates in gases and liquids from 50 cc/min to 20 GPM, with choice of alloy or plastic housings. Shuttle models are used with high flow rates from 0.5 GPM to 100.0 GPM. Paddle models are for larger line sizes, typically 1.25"" and up. Thermal dispersion technologies feature no moving parts, making them ideal for applications where particulate matter is also a concern. Electronic flow switches encompass state-of-the-art electronics and positive visual indication.All Gems flow switches feature high-quality, corrosion-resistant materials, ensuring their continued performance within challenging environments. Material choices, ranging from stainless steel to Ryton, further offer vast chemical compatibility. In addition, models are offered with fixed or adjustable actuation settings; viscosity compensation or high pressures; media compatibility with slurries and particulates; as well as in-line models and designs to satisfy any mounting or space requirement.A custom flow sensing solution can also be designed and manufactured in OEM volumes. Often times, custom sensors may be produced with more competitive lead times than many industry off-the-shelf solutions.Detailed specifications on Gems flow sensors and switches are available from your Carotek application specialist.

PRESSURE

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. Industrial pressure transducers are available with ratiometric output for continuous real-time monitoring. 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. Products include:

PRESSURE TRANSDUCER & OIL PRESSURE SENSORS

CVD Pressure SensorsThin Film Pressure SensorsCapacitance Low Pressure TransducersMMS Pressure TransducersDigital Pressure Gauge & Transducers - 9000 SeriesThe 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. Capacitance-based pressure transducers, for example, are ideal for higher volume use. Sputtered thin film pressure transducers are specified where the highest possible measurement accuracy must be achieved. 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. Repeatability ranges are typically from 0.25 percent to 5 percent of the set point. The unique design of Gems pressure switches incorporates a special diaphragm/piston mechanism. This feature combines the benefits of high proof pressure piston technology with high repeatability, along with added resistance to vibration, pressure spikes, and temperature variations. For especially tough environments, Gems further offers a CVD-based solid state pressure switch with a field-proven ASIC design. A full family of water pressure switches is also available, with high-reliability over a standard range of 2 to 6000 PSI.Available pressure switch enclosure options include aluminum, stainless steel, brass, reinforced plastic and zinc-plated steel. Wetted parts include choice of Buna-n, Teflon® coated Kapton®, stainless steel, PTFE, EPDM or Viton® diaphragm. Standard pressure port options include stainless steel, brass, zinc or aluminum. Extended ranges or other features are available upon request.Most standard catalog pressure transducers and switches can be easily modified with alternate connectors and housings. In addition, a custom solution can be designed and manufactured in OEM volumes, often with lead times shorter than many industry off-the-shelf solutions.Detailed specifications on Gems pressure sensors and switches are available from your Carotek application specialist.
