Design and Manufacturing Engineering Services Customizing with Confidence

For nearly 60 years, thousands of OEM customers have placed their trust in the product quality and reliability of Gems Sensors & Controls. Throughout its rich technical history, the company has served as an invaluable provider of field-tested solutions to complex measurement challenges. Manufactured products include standard and custom liquid level, flow and pressure switches, miniature solenoid valves, and fluid systems for a variety of markets.

Engineering excellence is at the cornerstone of every Gems product. This is passed onto customers in the form of a well-designed, highly robust solution with extended service life. So, what happens when a larger-scale OEM application calls for something more "out of the box" than "off the shelf"? What if a custom solution from another manufacturer is already designed-in, yet not meeting expectations? What if the new custom solution is needed in a relatively short timeframe, and yet the legacy technology, or supplier, is now obsolete? Solutions to these problems for many qualified OEMs may be found in Gems custom engineering services.

fluid handling white paper  Tackling Tough Fluid Sensing Challenges
If an application calls for the accurate fluid sensing of liquid level, pressure or flow, Gems Sensors & Controls can help. Their extensive fluid sensing portfolio has evolved from nearly 60 years of field-proven successes in a variety of markets.

Common customer fluid sensing challenges can include the point-level or continuous level sensing of hydraulic oils. They might involve the monitoring of sticky, corrosive, lubricating or coating fluids. They could require reliable measurements of sticky foams and suspended solids. Or, perhaps the monitoring of fluid media with changing dielectric properties or highly stringent anti-contamination requirements. Whatever the challenge, rest assured, none is too great for the team at Gems.

 Key Instrumentation Considerations in Medical Gas Delivery Systems

The provisioning of medical gases to hospitals, mobile health providers and in-patient care environments requires absolute conformance to stringent industry standards. As a result, manufacturers, distributors and facility safety managers must have complete confidence in supply quality and continuity. It is important to note that, whilst accredited governing bodies do set critical industry health and safety guidelines, they neither evaluate nor inspect medical gas equipment, facilities, pipelines, nor other infrastructure. Compliance is therefore the direct responsibility of the medical gas OEM or integrator, along with the individual facility into which such gases are delivered. Learn more about how Gems helps OEMs achieve required high-accuracy monitoring and control.

 Solving Difficult Customer Questions - graphic Solving Difficult Customer Problems

Sensors can help to answer key questions about products, systems and processes. The accurate empirical data they offer can be used to address concerns such as, "How hot is my boiler running?" "Do I have enough airflow within my oxygen delivery systems?" "Is sufficient oil reaching my engine?" "Do my hydraulic lines have sufficient pressure ?" As with any question, the first and most important step is to correctly frame it. And that’s exactly where Gems Sensors & Controls begins with its customers. Learn more about this unique process.

 Enhancing Pressure Sensors

Enhancing Performance with Pressure Sensors

Pressure transducers have become an invaluable tool for the protection and optimization of industrial equipment, converting fluid pressure into variable electrical signals that can monitor and control a system. Nevertheless, while existing transducers offer an impressive service, there is an ever-increasing
level of accuracy in the output of these components, thanks to the new methods in which sensor elements and electronics packages are constructed. These new methods have not only added functionality to pressure transducers, they have enabled the components to withstand particularly aggressive process conditions, extremes of temperature, mechanical shock and vibration. Learn more about new pressure sensing technologies.


Which Sensor Company is right for Your Needs?

When choosing a sensor or control device for the product you are manufacturing, you have many choices. Yet anyone with experience knows that, for ultimate long-term success, the attributes of an individual component are just the tip of the iceberg! What about the company that manufactures the sensor? What about their culture? Their overall capabilities? Are they reliable? Read on to learn more about choosing the right sensor company for your company's needs.

Fluid Level Sensors in Oil & Gas

Fluid sensing in Oil & Gas is more important than ever. Water, oils and chemical fluids are integral throughout the lifecycle of a well, and even more so with the increased activity in unconventional drilling techniques such as hydraulic fracturing. New techniques and regulations have added the need monitor a wide variety of chemicals along with processing flow back and produced wastewater. Liquid level sensing now goes beyond the issues of equipment performance and reliability. Today’s producers must contend with the byproducts of their operations to provide better protection against environmental contamination through better collection, storage and treatment. Learn how each of these steps is handled more efficiently, and with better assurance, when liquid level sensing is applied.

Choosing Temperature Sensors for HVAC and Chiller Equipment

Efficient operation of industrial HVAC and chiller equipment depends upon optimum temperatures of refrigerant and lubricating oil at various phases of the refrigeration cycle. The most common sensors for this purpose utilize negative temperature coefficient (NTC) thermistors of various resistance values. NTC sensor devices exhibit lower electrical resistance when exposed to higher temperatures. Learn more about how to choose temperature sensors for HVAC and Chiller Equipment.

Improving Mission Critical Cooling Systems With More Reliable Level Sensing

The choice of coolant level sensor may seem like an insignificant detail when designing complex machinery such as emergency generators and cranes, but if this sensor fails, the operator has no warning of dangerously low coolant levels. Emergency generators may fail to start when your customer needs them the most, and machinery can overheat to the point of breakdown, requiring expensive repairs and even more expensive downtime. Learn more about why reliable coolant level sensing is important.
