These thermocouples can handle the pressure

The new generation of TC921 and 924 thermocouples (photo) enables safe and reliable plant control in applications involving excessive pressure, such as for production of plastics. For example, the high-pressure production of polyethylene involves temperatures of approximately 650°C and pressures up to 4,500 bar. For handling such extremes, the thermocouples are configured in a special manner. The metallic-sealing connection is realized with either a high-pressure connector (as in the TC921) or with the use of “sealing lenses” (TC924), which have proven operating records in applications involving pressures up to 5,000 bar. — WIKA Alexander Wiegand GmbH & Co. KG, Klingenberg, Germany


Safety CPUs that educate themselves

With the introduction of new CPUs (rated for SIL 3/ Category 4) and new communication modules, this firm has expanded its product portfolio of H41q/H51q safety controllers. The CPUs (photo) enable self-education in a redundant system. When a CPU is replaced (which is possible while the plant is still operating) data and programs are automatically copied from the new CPU, which means that the CPUs do not have to be manually reconciled anymore. This serves to simplify handling and avoiding faults. The total system is also able to meet the requirements up to SIL 3, even while a replacement is in progress. The new CPUs also feature reload functions, which allow program changes to be made without stopping the system, and a fast error localization provided by a high diagnosis-detection rate. Two new communication modules are also introduced, which can be used to program the CPUs with ELOP II via Ethernet. This eliminates the need for an additional RS 485 programming bus. — HIMA Paul Hildebrandt GmbH & Co. KG, Brühl, Germany


Perform fast UV-VIS analysis with this process spectrometer

The OMA-405 (photo) is a rack-mounted ultraviolet-visible process spectrometer, which features a diode-array detector. The analyzer contains no moving parts and is designed for applications that require fast, reliable and maintenance-free monitoring of concentrations. Typical applications include: monitoring of Cl2; trace impurities; metal ions; sulfur- and nitrogen-based compounds; and clean-in-place solutions. Spectra are recorded by the 1,023-element diode array over the wavelength from 190 to 800 nm with a resolution of 1 nm. The analyzer is controlled via an embedded Windows XP industrial computer with touch-screen interface. Output signals include 4–20 mA, RS232 and Modbus (TPC/IP, Ethernet, serial). — Applied Analytics, Inc., Maynard, Mass.

A very large atomizer for spray-drying applications

With production capacities in excess of 135 m.t./h, the new F1000 (photo) is claimed to be the world’s largest atomizer for spray drying operations. The unit is especially suitable for applications in the chemical industry as well as for flue-gas desulfurization in power plants. The F1000 offers a larger version of proven technology. Rotary atomizers are said to be reliable, flexible, easy to operate and require very little maintenance. Meanwhile, they can handle a wide range of feed materials, including solutions, suspensions, emulsions and pastes. The F1000 will allow designers to achieve the required processing capacities within a single unit, thus significantly simplifying the plant design, reducing maintenance costs and making the best possible use of the space available, says the manufacturer. — Niro A/S, Soeborg, Denmark

This clamp-on flowmeter doesn’t mind if the pipe is hot

The WaveInjector (photo) was engineered to extend the temperature range of the firm’s Flexus ADM clamp-on ultrasonic flowmeter. A non-intrusive flow measurement is now possible at temperatures up to 400°C, even in explosive (ATEX-certified) atmospheres. When mounted with the WaveInjector, the flow transducers send the sound signals into the hot pipe via optimized metallic coupling plates. The coupling plates reduce the temperature so that high-temperature transducers are not required, while a metal foil ensures good acoustical contact between the coupling plate and the hot pipe. — FLEXIM Flexible Industriemesstechnik GmbH, Berlin, Germany

Reduce pump’s energy consumption with this variable speed drive

Employing pump sets whose flowrate can be matched to actual requirements could help save companies billions of kilowatt hours of energy per year, says the firm. The new PumpDrive (photo) is a motor-mounted, variable-speed drive for centrifugal pumps. The unit’s “piggyback” design offers a number of advantages, including: space-saving installation; no need for a control cabinet; simplified cabling; and ease of commissioning. Unlike ready to use integral motors, the PumpDrive allows integration of all motor brands specified in plant-owners’ work standards. — KSB AG, Frankenthal, Germany


No matter how large the diameter, this seal is leak-free

Introduced at Achema, Pecody is a dynamic compression cartridge seal that is especially suitable for very large-diameter sealing applications, which normally require complex and expensive mechanical seals, says Lammy’s export manager Christian Besse. The cost is about half that of a mechanical seal, and a completely leak-free seal is achieved, he adds. The Pecody handles slow rotation speeds (<2 m/s), pressures from vacuum up to 100 bar, and temperatures from –100 to 300°C, and the diameter size is unlimited. Typical applications include mixers (including those handling nuclear waste and cement), reactors, sterilizers, and horizontal dryers (including those handling abrasive powders). — Latty International S.A., Orsay, France


Only one hand is needed to measure surface free energy

The MobileDrop contact angle measuring instrument (photo) features a prism optics system to ensure a sharp image of the drop contour. Drop deposition with different liquids allows the surface free energy and its polar and dispersive fractions to be determined in a short time. The video camera is transferred to a PC notebook for performing the analysis of the drop shape and calculating the contour angles and surface energies with DSA2 software. The device is packaged in an ergonomic housing and can be operated with one hand. — Krüss GmbH, Hamburg, Germany


New releases of biotech software

With the release of PAS-X PHARMA V2.3 and PAS-BIOTECH V2.2, users now have additional support for integrating and using mobile devices. Because PAS-X is based on the current version of Windows Mobile 5.0 (operating system Windows CE.NET), the software’s functions are now available on pocket PC or PDA basis. Both products migrate to the database Oracle 10g, which has many enhancements such as scalability, high level of availability and administration. With a single sign-on function, users only have to authenticate once in order to use all services and product components they are authorized to access. Card-reader devices and biometric methods, such as fingerprinting, can now be used for authentification. Other new functions include those for creating and maintaining recipies (Master Batch Records Management) and the associated approval workflow. — Werum Software & Systems AG, Lueneburg, Germany

Built to seamlessly integrate with all leading brands of overhead stirrer, the Tornado evenly distributes high torque to all positions of the Carousel 6. The result is productive overhead stirring, even when faced with highly viscous liquids. The Tornado can stir reaction mixtures of up to 10,000 cps at 500 rpm, and the system is also suitable for dispersing solids in lower viscosity liquids at speeds of up to 1,000 rpm. Built to minimize setup time, the Tornado features an easy-to-use “Pinch Grip” for fast, reliable, overhead stirrer shaft insertion. — Radleys Discovery Technology, Saffron Walden, U.K.


The advantages of forced feeding

Instead of relying on gravity to feed granulators, this patent-pending device evenly and horizontally feeds material to the grinding rotor using a screw conveyor system. Compared to traditional configurations, the new method is said to increase throughput by 30 to 50%, reduces the generation of fines and dust, and prevents flyback. Because a smaller feed port is needed, acoustic emissions are also reduced, compared to conventional belt or manual feeding units, says the firm. — Herbold Meckesheim GmbH, Meckesheim, Germany


Keep dust under control with this bag-filtration system

The Aer-Bag bag filter system is suitable for centralized dedusting of various production machines in a wide range of industrial processes. The system is said to be the ideal solution for problem-free removal of large quantities of dry and free-flowing dusts. The unit’s large filtration area is kept clean by reverse-flow air cleaning. Units are sized to meet the needs of a given process. — Aeron S.r.l., Cernusco Lombardone, Italy


Steam-sterilizable separators for lab to production

An improved range of steam-sterilizable separators was launched at Achema. The separators cover the entire range from small (CSC6; 50–150 L/h), pilot (CSC; 250–400 L/h) to large, industrial-scale applications (CSC 170; up to 10,000 L/h). The nozzle-type HFC 15 (photo) is the smallest (800–2,000 L/h) separator of the company’s Viscon technology. The Viscon nozzle automatically changes its throughput to ensure a constant solid concentration in the discharge. With their “hydrohermetic feed,” the steam-sterilizable separators all provide extremely gentle product treatment and hygienic design. The units are supplied as a function-tested, turnkey package with full steam sterilization, which eliminates the risk of recontamination. Other methods only sterilize certain areas, such as the bowl, says the firm. — Westfalia Separator AG, Oelde, Germany


This very large drum mixer has no moving parts

With a production volume of 25,000 L and a weight of 20 m.t., this new mixer (photo) is claimed to be the world’s largest horizontal drum mixer. Two units have already been installed in France and Canada for handling granular products in the food and pharmaceutical industries. The mixer’s rotating drum is fitted with internal tapered scoops, which induce a gentle 3D figure eight flow pattern. After a set mixing time is achieved, an outlet valve opens to allow the product to flow out of the mixer. Because there are no moving parts inside the mixer, no energy, frictional heat or shear forces are directed onto the product. — Lindor Products B.V.,

Dordrecht, Netherlands


A smart controller for pneumatic on/off valves

Neles SwitchGuard is an intelligent controller for pneumatic on/off valves. Designed to meet the requirements of process-critical switching operations, SwitchGuard is especially suitable for high-cycling applications where reliability and large capacity are demanded. The diagnostic features of the controller enable users to “see” what’s happening inside the valve, by looking at parameters such as friction and pneumatics failure; this information can be used to identify a potential problem before it becomes serious. SwitchGuard can also be used to control valve opening and closing with ramp profiles. — Metso Automation Oy, Helsinki, Finland


A fast way to process microscopic images

Digital microscopy and image-processing technologies reduce the effort required for manual and visual tasks when performing quality assurance analysis. A new analySIS family of specialized image-processing solutions (photo) has been introduced for materials inspection applications. This collection of software and imaging systems ranges from basic image acquisition and documentation software through to complete automatic inspection systems. For example, using analySIS start, perfect images are acquired, particles are counted, dimensions are measured, or distances are calculated at the push of a button. With analySIS pro, complex image-analysis tasks are performed automatically. New techniques are included for tracking objects or for particle analysis, using line-intercept methodology. — Olympus Life and Material Sicence Europa GmbH, Hamburg, Germany

This rotory vane pump does not need a gearbox

Pressures up to 14 bar are possible with the new LVP rotary vane pump, launched at Achema. The LPV, which is available in 316 stainless steel with carbon-filled PEEK blades, is designed to handle corrosive liquids of low viscosity (1–500 cSt) at temperatures of –50 to 260°C as well as flowrates up to 45 m3/h. The pump’s wide inlet port allows it to run at motor speeds, without the need for a gearbox, at flowrates of 30 m3/h. Narrow running clearances give the pump a high volumetric efficiency, and the entire casing is hardened to Rockwell C to better resist wear, says the company. — Viking Pump, Inc., Cedar Falls, Iowa

Suitable for critical laboratory and pilot applications, the system was developed to provide high performance and safety with lower maintenance requirements. In addition to fast heating and cooling rates, the system can maintain precise temperatures over a wide range. The units can be used for jacketed reactors, large rotary evaporators, reaction calorimeters, fermenters, and for cooling analytical equipment. — Thermo Electron Corp., Newington, N.H.

A device to measure O2 in hazardous areas

The 5100 i.s. is a portable, intrinsically-safe oxygen analyzer to replace the 570A hazardous-area analyzer, while an infrared version is claimed to be the first intrinsically safe IR device to provide a single percentage measurement for carbon dioxide, carbon monoxide or methane. Considerably smaller than the 570A, the 5100 i.s. uses non-depleting magneto-dynamic paramagnetic or IR sensing technologies (depending on the gas being detected) to ensure high reliability and low cost of ownership. — Servomex GmbH, Hamm, Germany


A new software version for plotting data

SigmaPlot 10 is the latest version of this scientific graphing and data-analysis package, which features new graphing options and many workflow efficiency improvements. For example, new 3D mesh plots (photo, p. 42I-8), including the contours, enhance the visualization of 3D data sets by projecting values on either of the xy planes. The curve-fitting engine has also been enhanced, and a new Dynamic Fit Wizard complements the Regression Wizard to find the best solution to difficult curve-fitting problems. A new ROC Curve Analysis Module can be used to help determine the best clinical test, and 12 new probability functions are available for calculating hypothesis tests. — Systat Software GmbH, Erkrath, Germany


This firm can help keep turbo drives operating

The proper maintenance overhauling and repair of drive components are the focus of a new service concept for turbo couplings. The project comprises more than 150 individual measures. The main points are a faster worldwide spare-parts supply, the optimization of repair management and the strengthening of local service competency for the entire plant. For example, a “Health Check” of the complete drive train (where vibration, temperature and pressure are analyzed) significantly minimizes the risk of costly, unplanned outages, says the firm. To optimize spare-part inventory on the customer’s site, an additional measure provides a targeted supply of critical and long lead-time spare parts. — Voith Turbo GmbH & Co. KG, Crailsheim, Germany
