Milltronics MSI and MMI Belt scales (photo) are now available for use on systems with flowrates of up to 12,000 ton/h, an increase of 7,000 ton/h. The MSI and MMI, combined with a Milltronics BW500 Integrator and speed sensor now have OIML (International Organization of Legal Metrology) and MID (Measuring Instrument Directive) approval, which guarantees the belt scales meet strict requirements for weights and measures applications in accuracy and repeatability. The MSI is used for rugged applications in process and load-out control. It provides instant response to belt loading and overload protection to 300%. The MMI is a high-accuracy, multi-idler belt scale consisting of two or more MSI scales. Used for critical process and load-out control, the MMI-2 offers an accuracy of up to ±0.25%. For greater precision, the MMI-3 can be used for applications requiring accuracies up to ±0.125%. The MSI and MMI models can be installed without the use of cranes or other high-cost resources. — Siemens Industry Sector, Industry Automation Div., Nuremberg, Germany
The Universal Modular Boiler U-MB (photo) steam-boiler series uses the shell structure with three-pass technology in the performance range of up to 2,000 kg/h. The boiler consists of several modules that are selected specifically per order. The heat generating component — the steam module and the Economizer module — are configured to suit the emissions and steam quality requirements. The basic equipment includes technology for teleservicing capability and an intuitive LBC TouchScreen control. An automatic startup mechanism means that the steam generator can be started up automatically at the press of a button or using an external starter from the cold state. Overload protection ensures high-quality steam irrespective of consumer behavior. — Loos Deutschland GmbH, Gunzenhausen, Germany
The Conterna (photo) is a continuous kneading and extrusion machine designed for processing highly viscous materials, such as plastic compounds with a high percentage of fillers.

The system normally has six kneading chambers, but allows for the arrangement of as many chambers in line as necessary. Discharge units, such as a gear pump or an extruder, can be mounted to the last kneading chamber. The machine is available for throughputs from approximately 10 to 4,000 L/h. — IKA Werke GmbH & Co. KG, Staufen, Germany
The CSF Steam Water Mixer (photo) provides a safe, simple and reliable source of hot water delivered at the correct temperature and pressure, so it is suitable for cleaning and wash-down applications. These mixers are constructed from stainless steel and are capable of delivering up to 10,000 L/h of water at temperatures up to 95°C. They are simple to install because existing steam and cold water supplies can be used. Running costs are minimal because the design of the mixer ensures that all the heat energy in the steam is transferred to the water. — Pump Engineering Ltd., Littlehampton, U.K.
VMY ’56 is the official designation of the new generation of this firm’s refrigeration and process-gas compressors (photo). It is the synthesis of 35 years of experience with former VMY series and will replace the well-known series VMY ’46 in the medium term. Designed for all common refrigerants, the VMY compressors are especially applied in the industrial refrigeration technology as well as for mixed gas and process gas in the chemical- and petrochemical industries and in power plants. At present, the first sizes VMY 256 M HR and VMY 256 M NR are available, reaching a conveying volume of 911 m3/h up to 1,375 m3/h at 50 Hz as well as a maximum pressure difference of 25 bar. In addition, the serial production of the size VMY 156 M — also available as male and female drive and with a volume flow of 444 m3/h up to 678 m3/h — will start in short time. The rotors of the new compressor stage are made of surface-hardened special steel for long service life. The profile 4 + 6 developed by Aerzen for the secondary rotor drive has been proven by its high reliability. The first rotors with this material and the drive on the secondary rotor side have been in operation quite successfully for more than ten years. — Aerzener Maschinenfabrik GmbH, Aerzen, Germany
Since it was launched last September, Spectro xSORT’s original metal analysis capabilities have been expanded to include applications for RoHS (Restriction of Hazardous Substances) Directive compliance and lead screening as well as for the examination of soil in environmental testing and the direct analysis of ores, concentrates and tailings.

The coupler can be configured as a class II master. Actively participating in the fieldbus communication, the interface allows clients to be diagnosed and logged via additional OPC-Server software, or to be configured and parameterized via AMS-Suite. — Hans Turck GmbH & Co. KG, Mühlheim an der Ruhr, Germany
The MT Series of Multipoint Mass Flowmeters (photo) are designed for gas and air applications, including continuous emissions monitoring systems, and thus are suitable for measuring and monitoring stack emissions. The flowmeters are ISO 14164:1999 (E) Annex B compliant and specifically designed for combustion air and fluegas measurement and monitoring in large ducts with irregular velocity profiles. Accuracies of ±2% of reading and repeatability of ±0.5% are possible thanks to the flowmeter’s ability to average up to 16 individual flow sensors at temperatures up to 450°C. The devices include continuous auto-test function and alarm diagnostics. Other features include averaging filters, which dampen response to rapid process fluctuations; RS 232C serial ports, to enable communication with field instruments; and menu-driven control for ease-of-use. — Allison Engineering, Basildon, U.K.

The Model 740 Membrane Test System (MTS) is the first commercial instrument designed specifically for measurement of the through-thickness resistance and conductivity of ionomer and polymer electrolyte membranes. Only a small sample of bare (non-catalyzed) membrane is required, eliminating the time-consuming and costly requirement of catalyzing the membrane, and assembling and running a fuel cell. The MTS is a compact, bench-top unit and uses membrane samples that can be easily loaded with membrane compressions up to 400 psi. The environment in the closed cell can be controlled between 30 – 120°C, relative humidity (RH) from dry to 95% and pressure from 1 – 3 atm absolute. — Scribner Associates, Southern Pines, S.C.
To meet food manufacturers’ stringent standards of freshness and quality, this firm introduces the SealTester, a rugged instrument that checks packaging for air and gas tightness inline. The key advantage of the SealTester is its saving in personnel costs compared to random physical sampling and testing. Another benefit is its extremely high level of dependability and consistency when checking for air or gas leaks, without any loss of the product being tested. The SealTester uses a powerful servo control to direct its six servo motors. The control manipulates three measuring belts in such a way that the flexible bags in the production line do not collide with each other nor with the belts. — Sartorius Mechatronics Corp., Bohemia, N.Y.

The unit can be configured for a variety of process controls, including: gas mixing and blending; gas ratio control; simple batch processes; triggering alarms; starting or stopping gas flows automatically under user-defined conditions; and gas flow totalization. The Compod controls simple processes without the need for external PLCs or computers. It monitors the operation of instruments, providing potential problem alerts, and is available with a LCD display for local monitoring. — Sierra Instruments, Monterey, Calif.
The LWY-SC-RF Loss-In-Weight (LIW) Rotary Feeder (photo) is designed to handle extremely free-flowing and fluidizable materials. Ideally suited for applications discharging into pneumatic conveying systems, the feeder system is available in a range of sizes and can be configured for either continuous LIW feeding or batch. Weighing is done through a patented low-deflection, non-wearing FMSS (Force Measurement Suspension System) flexure scale, which measures vertical loading and can take high-load directed overloads (1,000%). The FMSS Scale design uses counterweights to negate the tare weight of the support structure, feeder and bin, allowing 100% of the scale capacity to be used to weigh material. — Thayer Scale, Pembroke, Mass.
