Zumbach Electronic AG has recently extended its range of Steelmaster rod and bar gauges with a further and larger model. The new gauge, SMO 160-S6, is equipped with six high-speed laser scanners ODAC® 160 and delivers up to 6,000 measurements/s ie 1,000 processed profiles/sec. It also features Zumbach’s calibrated single scan system (CSS) and the unique EPM method and software. The gauge is able to measure rounds, hex, squares, flats and various shapes with outside dimensions up to approximately 140mm (depending on product vibration) in multiple modes: • Static, orientable mode: measures in six directions, 30 degrees spaced • Partial oscillation mode: programmable start and stop angle, eg for squares or flats • Full 180° oscillation: standard mode for rounds, every 30° rotation delivers a full profile The new EPM method and software, in combination with CSS, makes the gauge a very effective tool at three roll blocks or when the bar has polygonal or asymmetric shape deviations, eg asymmetric underfill or overfills. It calculates the typical values DT and GT for the initial roll settings. It can also calculate and displays “Roundness” RON t according the official ISO definition for any shape.

The mechanical system is the same as the well proven design of the smaller gauges and requires minimal maintenance and periodic cleaning only. Smaller gauge models for wire rod and smaller sizes are also available.

Beating the cold conditions for wind turbines

9609-80 and Apex N-56001 to provide cable manufacturers with different options for meeting application requirements,” said industry manager Mike Patel. “Both products are high-performance alternatives to the standard flexible vinyl compounds used in cable jacketing and are particularly valuable for their cold-impact and oil-resistance properties.”

• Apex® N-56001 is a 76 Shore A blend of PVC and nitrile rubber that provides superior long-term low-temperature flexibility and oil resistance. It exhibits a brittle point of -54ºC. Besides exceeding application standards for impact resistance at temperatures down to -40ºC, both compounds pass required tests for UV resistance, 60-day oil aging at 75ºC, and flammability performance as specified in UL 1685-F4. The two compounds are rated at 105ºC for maximum continuous operating temperature.

Two high-performance vinyl jacketing compounds from Teknor Apex withstand the harsh cold, exposure to lubricants, and other challenging conditions encountered by control and power cables within the nacelles atop wind turbine towers. Drawing on its expertise in compounding elastomeric materials, Teknor Apex has taken two different approaches to meeting the rigorous requirements of wind turbine applications: • Flexalloy® 9609-80 is an 80 Shore A PVC-based elastomer that provides superior long-term UV resistance. It exhibits a brittle point of -60 ºC.
