60 Measurement and Testing On-Line, Real-Time Process Elemental Analysis by EDXRF
Featuring advanced third generation energy dispersive X-ray fl uorescence (EDXRF) technology, the Rigaku NEX OL represents the next evolution of process elemental analysis for liquid stream and fi xed position web or coil applications. Designed to span from heavy industrial through to food grade process gauging solutions, the Rigaku NEX OL is confi gurable for use in both classifi ed and non-classifi ed areas.
To deliver superior analytical performance and reliability, the EDXRF measuring head assembly was derived from the established Rigaku NEX QC+ high-resolution benchtop instrument. With this proven technology, the Rigaku NEX OL delivers rapid, non-destructive, multi-element analyses – from parts-per-million (ppm) levels to high weight percent (wt%) concentrations – for elements from aluminum (Al) through uranium (U). Equipped with a 50 kV X-ray tube and SDD detector – together with a standardized, optimised suite of tube fi lters – the Rigaku NEX OL is engineered to address a broad range of process control applications.

Explosion Proof In-line Hydrogen Process Analyser Product Highlight
Field Wireless Vibration Sensor with Fast Data Updates and Long Battery Life Released
Yokogawa Electric Corporation it has developed an ISA100 WirelessTM-based fi eld wireless vibration sensor with the ability to quickly update data as well as a long battery life. ISA100 Wireless is a technology that is based on the ISA100.11a standard. It includes ISA100.11a-2011 communications, an application layer with process control industry standard objects, device descriptions and capabilities, a gateway interface, infrared provisioning, and a backbone router. By providing real- time updates on vibration levels in plant facilities, the new sensor helps users quickly detect equipment anomalies and enables predictive maintenance.
With a fi eld wireless system, plant fi eld devices and analysers are able to communicate wirelessly with host-level monitoring and control systems. The rising need to improve productivity and enhance safety by collecting more data on plant operations is driving the demand for fi eld wireless devices, which can be installed even in diffi cult to access locations. Field wireless devices have the added advantage of reducing installation costs. Vibration sensors are useful for the condition monitoring and predictive maintenance of plant machinery such as compressors, pumps, and motors. Conventional methods for monitoring vibration include the use of vibration sensors that rely on wired communications with a host system, and patrols by maintenance staff to collect vibration data. With the widening use of fi eld wireless systems and the need to reduce installation costs, there is an increasing demand for wireless vibration sensors.
The HY-OPTIMA™ 2700 Series uses a solid-state, non consumable sensor that is confi gured to operate in process gas streams. The H2scan thin fi lm technology provides a direct hydrogen measurement that is not cross sensitive to other gases. The HY-OPTIMA™ 2700 Series is ideal for applications where real-time, hydrogen specifi c measurements can enhance process plant effi ciencies, diagnostics and maintenance management. Common applications include: Refi nery (Reforming, cracking, recycle, tail gas, fuel gas, fl are gas and other multi- component process streams), Natural Gas (H2 supplement to hydrocarbon measurement for complete natural gas or biomethane analysis), Industrial Gas Supply (Air separation, syngas, steam methane reforming, and electrolysis process streams), Petrochemical (H2 measurement in polymer feeds and fl are gas process streams) and Manufacturing (Metals annealing, semiconductor, oil hydrogenation and fertiliser manufacturing process streams).

Since releasing the world’s fi rst ISA100 Wireless-based fi eld wireless devices and wireless systems, Yokogawa has expanded its lineup of fi eld wireless devices that measure temperature, pressure, fl ow rate, and the like. This new vibration sensor will meet the company’s customers’ needs for a device that can provide the quick updates on vibration levels needed to detect anomalies at an early stage. The principal components of this fi eld wireless vibration sensor are the FN510 fi eld wireless multifunction module, the LN01 piezoelectric type acceleration sensor, and the FN110 fi eld wireless communication module. Via a gateway device, the FN510 uses the ISA100 Wireless communications protocol to exchange data with a host-level system such as a DCS. The data collected with this vibration sensor enables plant operators and maintenance staff to monitor vibration levels in real time.
Both explosion-proof and non-explosion-proof types are available. Key features of this sensor are as follows: 1. Fast data updates: The sensor can be set to update data as quickly as every 10 seconds. This update time is ideal for monitoring vibration levels in plant facilities. 2. Long battery life and easy maintenance: When the vibration sensor is set to update data once per minute, it can operate on a single set of batteries for up to 10 years. In addition to eliminating the cost of providing replacement batteries, this reduces maintenance workload. 3. Highly reliable and versatile system: Thanks to the features of ISA100 Wireless and Yokogawa’s technical know-how, the company has achieved a highly reliable wireless network with fully redundant communications that is capable of sending and receiving different types of sensor signals over long distances. Major target markets include industries such as oil and petrochemicals.
Applications include measurement of vibration levels of equipment such as compressors, pumps, motors, and fans Yokogawa released the world’s fi rst ISA100 Wireless system devices and wireless pressure and temperature transmitters in July 2010. In addition to enabling sophisticated control techniques in continuous processes, this gave customers a wider range of devices to choose from. Yokogawa will continue to expand its lineup of ISA100 Wireless transmitters and other devices such as adaptors to develop best-in-class solutions that provide higher value to customers, and promote the use of fi eld wireless technologies.
