Sectional load sense relief valve.

A new sectional load sense relief valve (LSRV) for its CLS mobile hydraulic control valve has been introduced by Eaton. The patented LSRV limits individual section pressure through feed oil reduction, eliminating the need for inefficient work port reliefs for feed-side pressure control. The CLS LSRV improves machine productivity and efficiency by helping prevent functions from slowing down during multi-section actuation and by eliminating unnecessary energy consumption and heat generation.

“Most load sensing mobile valves make you choose between power management and pressure control,”
said Jiri Foukner, EMEA product manager, Advanced Mobile Valves, Eaton. “Eaton’s CLS valve eliminates this trade-off. With the new sectional LSRV, the CLS valve combines the benefits of pre-compensated and post-compensated valves, providing pressure control while maintaining flow sharing and power management capabilities.”

The CLS LSRV enables the use of full available inlet flow to maintain functionality during multi-section actuation, helping improve machine productivity. The LSRV limits pressure by reducing feed oil flow, rather than dumping the flow to the tank. Once the LSRV stops oil flow when a function reaches a specific pressure, which can be lower than maximum system pressure, that flow is available to other sections at full system pressure. This helps prevent machine functions from slowing down when multiple sections are operating at once.

The CLS LSRV improves energy efficiency by minimizing the power losses that occur when using work port reliefs for feed-side pressure control. Unlike work port reliefs, which dump all oil flow to the tank, the LSRV discharges only 2 to 4 L/min. of flow to the tank, dramatically reducing energy consumption and heat generation. 

The CLS sectional load sense relief valve is ideal for machinery with swing and clamp functions, including forestry equipment, excavators and backhoes.

Raman spectrometers provide IIoT connectivity.

Integrated Raman spectroscopy analyzers provide highly accurate in situ measurements while providing 24/7 connectivity to critical data.

The embedded Kaiser Raman Rxn analyzer suite, featuring intuitive Raman* RunTime embedded control software has been released by Kaiser Optical Systems, an Endress+Hauser company.

Researchers and manufacturers in the chemical, polymer, pharmaceutical, biopharmaceutical, and food & beverage industries require highly accurate chemical composition measurements. In the past, Raman spectrometers required the use of separate stand-alone computers hosting the software needed to convert raw measurements into usable data. Because of installation and system limitations, measurements often took place offline in a controlled laboratory setting, limiting accuracy and lab-to-process scalability.

In contrast, this embedded analyzer collects in situ process measurements, enabling real-time process monitoring, optimization, and control. With this 24/7 automation, companies can maintain a continuous pulse on the safety, quality, and efficiency of their operations—whether in laboratory or manufacturing settings. Kaiser Raman Rxn analyzers perform self-monitoring and self-diagnostics to ensure the validity of each measurement, and to enable seamless model transferability and equipment scalability from lab-to-process.

This latest Raman Rxn portfolio, comprised of the Raman Rxn2 and Rxn4 base analyzer models, integrates analyzer and control software in a fixed purpose device with built-in intelligence. Kaiser Raman technology also communicates with external systems over networks using standard automation protocols, providing companies with reliable chemical composition measurement with secure 24/7 connectivity. By doing so, the analyzers enable an Industry 4.0 strategy of increased data security, system integration, and automated communication.

To ease maintenance, Raman Rxn2 and Rxn4 analyzers perform self-calibration, utilizing spectral correction methods in applications when periodic system calibration is not required. Additionally, they provide flexible installation options including benchtop, mobile wheeled cart, and rack-mounted, or in stainless-steel enclosures for lab, pilot plant, or dedicated manufacturing applications. The rugged analyzers and applicable sampling probes are also certified for installation in hazardous areas.

Kaiser Raman embedded analyzers can be configured with 532, 785, or 1000 nanometer excitation wavelengths, with the ability to measure up to four channels. Measurements can be taken inline, online, or at-line. Common applications include analyzing material quality, monitoring molecular reactions, aiding basic science research, assuring quality, and identifying unknowns.

The analyzer’s built-in software provides 24/7 connectivity to process data via a user-friendly touchscreen or through a remote interface. Raman RunTime integrates measurement with analyzer electronics, eliminating the need for a separate PC and software to interpret measurements. It conveys either raw or processed data and diagnostics over standard communication protocols—including OPC and Modbus—to assure data integrity and compatibility with third-party devices.

Data may be collected manually, continuously, or periodically—with support for embedded predictors. The analyzers’ controller technology is designed for inherent security as a fixed-purpose device to minimize inadvertent or malicious user interaction. Additionally, it does not interact with low level operating systems because all control functions are directed via the software user interface. It also provides user management, password protection for privileged analyzer functionality, and built-in antivirus software to minimize potential malware points of entry.

Kaiser Raman technology supports the needs of Industry 4.0 with smart power controls, enhanced diagnostics, remote laser interlock, robust fiber connections, and automation input/outputs. By delivering highly accurate, real-time, in situ chemical composition measurements and 24/7 connectivity, the Kaiser Raman Rxn embedded analyzer portfolio helps companies reach new heights of operational excellence.

Bespoke signal conditioning service.

Where can you go when you need a custom signal conditioning solution? No doubt that there a few specialists that can build the system you need but they will be using components from different suppliers which might cause problems if a fault develops. 

The bespoke design and build service from Kistler uses in-house components and, when necessary, components from trusted suppliers. It is important to realise that Kistler takes responsibility for all the components, not just those with their own brand; if any component fails, Kistler will fix it.

One project recently completed was for a portable test system that can measure 160 channels. This required two portable, shock-absorbent and water-resistant racks each with twenty 8 channel charge amps, a 24 port Ethernet switch with time synchronization, shielded Ethernet cables and a DC power supply. To keep the temperature in the racks within the maximum 60°C operating temperature in an ambient of 21°C, active fan cooling was also required. Add to this, a high spec, custom build computer running specialised software was needed to control both racks.

Not every application will require 160 channels although some may demand even more. The bespoke signal conditioning system service from Kistler delivers exactly what is needed for any application, no more and no less, and with a guarantee that the rig will fully meet the detailed specification.

Leakage current sensor.

The CDSR, a new leakage current sensor based on its open-loop Fluxgate Technology has been launched by LEM. The CDSR is innovative, extremely compact and safe, allowing manufacturers to optimize the electronic design of their charger products.

With a worldwide total of only 7.3 million EV charging points, of which 6.5 million were private in 2019, the lack of an extensive charging infrastructure is a key impediment to the growth of the global electric vehicle market. To support the massive deployment of EVs, driven by ambitious policies to phase out sales of internal combustion engine (ICE) vehicles, the charging infrastructure must increase by thirteen times. 

Due to this high expected demand, manufacturers of electric chargers must develop solutions that are competitive, affordable and capable of being industrialized at high volume. As well as being easy to install for the end user, they must meet many standard criteria, both for safety and robustness of the product.

Since 2016, IEC standards and more specifically IEC 62955 / IEC 62752, require the detection of a Direct Leakage current at 6 mA DC to avoid the home Residual Current Device (RCD) Type A being ineffective. This effect, called “the blinding effect”, appears when an EV develops an insulation fault. 

EV architecture integrates a battery pack, powered by Direct Current (DC), which can generate a leakage current that can deactivate a home RCD. To protect the RCD and avoid the need to install an RCD type B in the electrical panel of home EV owners, EV chargers include a device to detect the DC leakage current. This detection is the role of the CDSR. 

The CDSR has been developed to meet market demand for a residential and commercial charging station, offering a version for single-phase architecture and another for three-phase topology. With a maximum current per phase of 32A rms, the CDSR can be integrated into AC chargers from 3.7 kW to 22kW.

Following the trend towards digital electronics, the CDSR provides not only an analog communication output but also a Serial Peripheral Interface (SPI), enabling simple interfacing of hardware.  The CDSR operates from a +3.3VDC supply and has a typical current consumption of just 50 mA when measuring 150 mA as a maximum primary residual current.

The ratio-metric behaviour of the CDSR ensures it can resist power supply drift and maintain a stable output measurement.

Extremely robust, the CDSR can operate inside all EV chargers. It has an operating temperature between -40°C to 85°C, can withstand acceleration forces up to 10G while maintaining nominal performance, and has a very high level of insulation between its primary and measurement circuits, thanks to long creepage and clearance distances (13.2 mm).

Designed to ensure a high level of safety, the CDSR provides a default detection output signal with a reaction time below 200µs. Combined with an independent test winding, charger manufacturers can test the performance of the sensor in real time to guarantee maximum safety.

The CDSR provides an essential component of the electrification world, making charging infrastructure more affordable, safer, and reliable for the future. This new technology, developed by the experienced LEM Geneva R&D team, opens the door to new horizons using DC systems to reduce CO2 footprint.

Analysis of Multi-fibre Connectors.

Easy-to-Use Analyzer for Working in Data Centers.

The FOCIS Lightning connector microscope provides a complete pass / fail analysis for a 12 or 24-fibre MPO connector and each individual fibre in just 15 seconds. This easy-to-use instrument captures the entire connector surface in one step. This saves valuable time when setting up and maintaining multi-fibre connectors in data centers, for example.

During analysis, the user may choose between all common telecom standards according to IEC, IPC, and AT&T. However, he may also define and configure his own specifications.

The FOCIS Lightning works completely autonomously and does not need to be connected to power or data networks. Results can be transmitted instantly via Wi-Fi or Bluetooth. A free app for mobile devices is available for download. However, the microscope also offers internal memory for up to 10,000 images, which can later be used for documentation or detailed analysis.


• In Germany, the FOCIS Lightning and other measuring devices from AFL are distributed by LASER COMPONENTS.
