Compressed air is one of the most critical and expensive utilities in any manufacturing facility. That said, maintenance and monitoring of this crucial system are largely ignored. When it is given attention, the focus is usually in the compressor room. The piping distribution system — where most problems exist — is often ignored. This is a costly mistake. Incorrectly sized piping, leaks, rust, or other undetected issues in the piping distribution system are often the real issue – and quite simple to fix.
To fully manage your compressed air system and pinpoint areas of inefficiency, pressure, humidity, flow, temperature, and power should be measured and monitored.
To identify where to measure the above data points in your facility, a site survey must be done. A site survey is a walkthrough of the facility with a trained professional. The trained professional will ask you questions about the facility and what pain points you have. Using the answers from questions and their observations, the trained professional will provide the recommended mix of sensors and placement locations. If going with a wireless monitoring solution, the site survey will also identify any communication dead zones or obstructions to avoid when installing the sensors.
Be confident and informed about your compressed air system. Schedule a condition monitoring site survey and reduce your energy costs and increase your productivity and uptime.
Every 2 psi of air pressure generated equals 1% of a compressed air system’s total energy cost. Having an inefficient compressed air system could be costing your tens or even hundreds of thousands of dollars in wasted energy. These inefficiencies result from several causes including:
Any of these issues can cause your compressor to work overtime, ultimately shortening its life expectancy.
To identify and address these issues, take pressure readings throughout the compressed air system at key locations in the compressor room, at point of use and throughout the piping distribution system. Your key locations will be identified through the site survey. This will provide a total system pressure profile. Without this holistic approach, you may know that a machine is being starved for air, but will not know where pressure starts to drop — critical information for troubleshooting. Your compressor may be completely adequate for your application, but if you have undersized or corroded piping, adding more compressor capacity isn’t going to help.
You can take these measurements manually with a pressure gauge, but that gives you only a snapshot of the data at a particular point in time. For ongoing information about your system, you can install sensors throughout the system. Wireless sensors reporting to the cloud make this task simple and cost-effective.
Monitoring humidity in your compressed air system provides early detection of system complications. Excess moisture corrodes pipes and damages internal components of machinery, increasing maintenance costs and causing production downtime. In precise manufacturing such as painting applications, excess moisture causes quality control problems in the form of product damage and paint not adhering. Moisture breeds harmful bacteria that contaminate finished goods.
The use of humidity sensors can prevent these issues. By monitoring the humidity in the compressor room lines and point of use, you can confirm your system is operating at peak efficiency. A site survey will identify if additional humidity sensors are needed in your facility. High levels of humidity in your system can indicate either a problem with the dryer, condensate removal system or simply the location of the compressor and dryer.
A common cause of inefficient air systems is clogged piping. Over time, the interior or older steel piping corrodes, restricting the flow of air. Undersized piping also causes inefficiencies in the compressed air system. In most cases, the piping was correct for the original demand, but as the facility grows and demands more air, the piping system becomes too small to deliver the correct air pressure to the point of use.
Leaks also cause compressed air system inefficiencies. Leaks are mainly seen in older pipes, but newer installations can still leak as well. Eventually, threaded connections start to separate, creating a path for air to escape from the distribution network. Installation mistakes will lead to leaks, as well as the potential for serious injuries. When attaching connectors, make sure to assemble the system to the manufacturer’s specifications to avoid leaks and potential injury.
Using the results of your site survey, placing flow sensors at the correct locations in your compressed air system identifies potential leaks, unnecessary or inappropriate uses of compressed air, and the demand of the entire facility and each individual department. The best way to check for system leaks is to monitor the artificial demand of air during idle (no production) times. The higher the artificial demand, the more leaks exist in the system. Analyzing the data also determines the health of the piping. The interior of pipes will corrode and create blockages without ever showing signs on the outside. An area with poor flow readings means the pipe has begun to corrode.
Monitoring the temperature determines the health of your compressor room equipment. To monitor the health, temperature sensors should be placed right after the key components (e.g. compressor, dryer, and storage tanks). Comparing the temperature readings to the optimal performance bands provides a quick check on the performance of the equipment. If the temperature is on the high side, the equipment is working too hard and could fail earlier than expected. If the temperature is on the low side, the equipment is underperforming.
Installing a power or current sensor on your compressor provides data on power consumption Using the data from the power and the flow sensors, you can determine the health of your compressor. When combined, these two data points allow you to calculate the cost per unit ($/cf) of compressed air. Analyzing the cost per unit determines if your compressor has performance problems such as short-cycling, faulty controls, or unregulated spikes. This also determines if your compressor is oversized for your application.
Compressed air is a costly, but vital utility in your facility. Monitoring your compressed air system’s performance identifies problem areas. By knowing these problems, you can make educated system improvements. Monitoring your system after making improvements ensures your investment is protected from reverting back to an underperforming system.

Point-of-care testing (POCT) is a rapidly expanding segment of the healthcare industry, especially for at-home care and disease management. This expansion is driven by an increasingly diverse array of advanced medical diagnostic equipment that can be used at or near the point of care, which leads to easier testing and faster clinical decisions. POCT equipment measures a wide range of health indicators, including blood glucose, electrolyte concentrations, cardiovascular markers, cholesterol, drug levels, urine chemistry, infectious diseases, organ function, and immune response.
Another reason POCT is growing in demand is that these instruments are becoming more advanced in terms of functionality, yet at the same time also smaller and more compact—making them easier to use (which improves at-home compliance). POCT equipment runs the same tests that the larger in-vitro diagnostic (IVD) systems do, but is designed as a handheld or bench unit, requiring much smaller volumes of fluid samples and reagents, while also delivering rapid testing and precise analysis.
Download this application note to learn how to streamline point of care instrument development.
POCT manufacturers must balance a number of scientific disciplines to create a POCT device, including mechanical, chemical, and software engineering. The first step in developing a device is understanding the chemistry of the test (for example, molecular diagnostics, immunochemistry, or other assay).
Scaling down both the fluidics and the chemistry for a device is not as simple as just making things smaller. Chemical reactions often behave differently as the volume is decreased. In many cases this has a positive effect on performance—for example, reactions often proceed more rapidly in small volumes, with less reagent consumption.
To make devices easier and faster to use, POCT engineers design into the instrument many of the steps that are normally performed by separate instruments in the lab. These include sample preparation, cell lysis, nucleic acid purification, amplification, and detection—all in a single cartridge. This saves time, reduces sample handling, and minimizes the potential for contamination or error.

Once the chemistry is scaled down, the next challenge is designing a compact, reliable, and cost-effective cartridge to contain the reagents and reactions. Such a small cartridge also requires miniaturized, high-performance components such as pumps and valves, which must be durable, precise in design, and chemically inert. Parker’s best-in-class 8mm X valve and 7mm C7 cartridge valves are examples of miniaturized components that provide the same performance as larger valves but within a very small footprint. This allows POCT OEMs to pack these fluidic components into smaller and smaller devices.
The final POCT design challenge deals with automating the precise movement of samples and reagents within in the cartridge to ensure tests are reliably and accurately performed. This requires a deep understanding of fluid mechanics and how pumps, valves, and manifolds can affect the movement of liquids in the cartridge. High-precision flow control is required for the samples and reagents as they make their way through the different reaction chambers within the POCT cartridge. Parker offers a variety of miniature solenoid valves to control delivery of reagents using either on-off, diverter or proportional control of flow methods. Both pneumatic pumps and valves or liquid pumps and valves can be used to move fluids through the different reactions. Electronic pressure controllers are also available to provide precise pressure control.
Parker Precision Fluidics understands the needs of POCT design engineers. We can help design the perfect fluidics systems for your devices, allowing you to focus on what you do best—the chemistry. Because we manufacture both pumps and valves, our engineers are highly experienced in the flow mechanics required for POCT and can provide reliable, complete, and cost-effective solutions. Solutions can be customized to your needs, including complete fluidic subsystems or components that are preassembled and tested for easy assembly into your products.

Cold weather may force designers to reconsider the usual technical choices regarding rolling stock systems.
Combining ergonomics of use, a cost-effective approach and technical performance are the challenges associated with a low-pressure circuit intended for use at cold temperatures.
This blog describes the specific features of the various connector technologies in a low-pressure circuit and provides a professional opinion regarding the choice of the onboard connection.
Fluid transfer low-pressure circuits on rolling stock consist of four main functions:
When choosing connectors, manufacturers and operators must consider in particular two main selection criteria which are the technology and the materials
The connector is chosen according to use criteria related to the disconnection frequency, speed of assembly, tube quality implemented and design habits. The four main connector types are as follows:
Push-in fittings: Available in three gripping versions (by washer, by gripping and by reversed gripping), to quickly create flexible and modular systems. The gripper technology is recommended for low-temperature applications down to -25 °C, while the washer technology can be used to temperatures as low as -50 °C.
Quick couplings: Available in three valve versions and with various standardised end-fittings, they are suitable for frequent connections-disconnections. This technology provides very good resistance down to -40 °C.
Spigot fittings: Easy to implement, they guarantee direct leaktightness on flexible tube with no seal and no anchor ring. Their resistance to cold, as low as -40 °C, depends on the tube quality.
Compression and bite type fittings: Available in two versions with separate ring or built-in ring, they adapt to all types of tube (metal or plastic). They offer exceptional resistance to cold, down to -60 °C.
These last two connection types are more complex to implement.
Fitting and tube form a pair which, when correctly associated, guarantee optimum operation of the low-pressure circuit over time.
Key factors when designing the low-pressure circuit, the materials play a role in the performance of the system and its resistance to cold through their composition and structure.
The tube material participates in the chemical and mechanical compatibility of the circuit. Being used throughout the circuit, it has a considerable impact on the resistance to cold. A flame-retardant version is available which can withstand temperatures down to -50 °C.
The materials of the fittings and other connection systems guarantee leak tightness, efficiency over time, the ergonomics of the circuit and operating safety. They are available in two versions: metal and polymer.
Other criteria must be taken into account when choosing the connector, for example pressure/temperature performance, compliance with standards and regulations. Taking into account all these criteria will guarantee that the connector is perfectly compatible with the operating conditions.
To conclude, the range of Parker LPCE low-pressure connector systems focuses on the safety of persons and goods, having provided solutions for all relevant applications in various types of train and rail vehicles for many years. Two quick-reference brochures detail everything you need to know about a selection of connectors and associated products.

The reliability of every component is significant for the design engineer of modern railway vehicles if they are to function smoothly in the long term.
The EO-2 fitting has been extremely reliable for application use in the rail industry. The soft-sealing fitting does not need to be re-tightened even after years of continual usage, and the seal is designed for long term cost savings.
Furthermore, it is always an advantage for the assembler when components are simple, safe and quick to install - easily carried out with commercial tools. But there are other benefits.
The main advantage lies in the design detail. The EO-2 was developed on the foundation of the Ermeto Cutting Ring System - a well-known concept. It features a special characteristic - a large-volume elastomeric seal. Invisible from the outside, the seal assures sustained function and leak-tightness even in extreme application conditions.
The profile of the EO-2 elastomeric seal shows a particularly large cross-section which seals safely even in unfavourable tolerance ranges of tubing and fittings. So the sealing effect is supported by the system pressure. This means that EO-2 fittings are well suited for high-pressure applications. Due to the high preload of the seal, the EO-2 design has formidable gas leak-tightness. This prevents the penetration of air in vacuum conditions.
In comparison with other fitting types, the EO-2 Series has an advantage because of optimal installation room without gaps and dead volume. For the user typical sealing damage such as spiral extrusion or wear caused by “pumping” are prevented.
An ever-recurring problem is under- and over-assembly. EO-2 eliminates this because before assembly of the fitting, a gap is located between the end faces of the sealing and retaining ring. This gap closes as soon as the retaining ring has reached its final cut depth into the tube. Assembly completion by this dead-stop is very clearly indicated. An equally good assembly outcome is achieved with manual assembly too. So completed assembly can be checked by an operator's quick visual inspection.
As soon as the gap between both rings is closed, the EO-2 connection is ready for assembly-inspection and installation. If the functional nut is then tightened to spanner tightness, it is sufficient to tighten the connection with 1/4 to 1/6 of a turn. This clearly noticeable stop point increases the user’s feeling of safety and prevents effectively dangerous under-assembly. And always remember this: “after fixed comes off”. This will certainly be avoided with EO-2.
EO-2 Fittings meet DIN 2353 and ISO 8434. They are available for tube sizes from 6 -42 mm O.D. – which covers most situations. For warm temperatures, it can be used with no problems up to +200 °C. Conversly, arctic temperatures pose no problems. EO-2 fittings are available in steel and stainless steel depending on your application.
All EO-2 fittings are certified in accordance with EN45545-2 and EN61363 and also have the IRIS certification. For the designer, this means a universally deployable fitting which meets the current certification standards. This significantly simplifies designs.
A big application range means wider design possibilities. EO-2 covers hydraulic and pneumatic applications. For the user, there are clearly reduced costs and assembly work. In addition, this fittings series is also well suited to restricted access situations.
EO-2 are well-greased and easily assembled. The threads of the standard smooth-coated retaining nuts are additionally treated with EO-LUB from sizes 25S/28L. The torques of EO-2 fittings are thereby reduced by about 25 percent and make their contribution to preventing dangerous under-assemblies.
In the EO-2 functional nut the sealing and retaining rings are assembled so that these three parts cannot be lost and form one design element. Because of this, individual parts such as seals and cutting rings cannot be forgotten, mixed up or fitted the wrong way round. All these kinds of mistakes that might be made must be avoided at all costs because they affect the safety of both passengers and railway personnel.
Individual parts do not have to be laboriously collected together during assembly. The user can shorten assembly times, reduce warehousing costs and into the bargain increase the security of his/her systems free of charge.
Viewed on the whole, the EO-2 Series, represents an attractive, safe and reliable alternative to comparable fittings systems. EO-2 is available world-wide and in the case of replacement, makes the procurement of the required components easier. EO-2 also meets the “Buy America Act.” Click here to earn more about on EO-2 Fittings or visit us in person at Innotrans 2018 at Hall 10, Stand 206 in Berlin from 17th to 21st September, 2018.
