The Lufft VENTUS sensor is a high-quality ultrasonic wind sensor proven to operate well in the most extreme conditions. The HALT test is a special wind sensor test that tests extreme corrosion, vibration, heat, and cold. All of this is done in a special wind tunnel that projects high-velocity wind toward the sensor in three vector directions simultaneously. The VENTUS survived to -139° F (-95° C) and 203° F (+95° C), and the maximum vibration and corrosive limits of the test. Lufft has plans to improve the sensor to reach -184° F (-120° C) to 248° F (+120° C) limits of functionality. The VENTUS wind sensor is designed with turbine control anemometry in mind. Resistance to ice with a 240W heater, and resistance to corrosion is accomplished with a heavy-duty anodized aluminum alloy. IP65 will assure the sensor will resist water intrusion in the strongest storms or offshore environments. VENTUS rugged wind sensor is available in an array of flexible communication options, including current or voltage. Each sensor is fully configurable with free software by Lufft.
Zarges is introducing its new rope-guided service lift, which is making the trip from the base of a wind tower to the highest internal platform more stable and userfriendly. The modular design of the new lift, which features a small, flat control cabinet and an external winch system, provides additional space for users. The control cabinet is accessible from the outside; the winch is mounted on a separate frame and electrical equipment is integrated into cable ducts. The design also enhances the driving experience by improving the transit of rope guides and incorporating torsion resistance into the cab. And, since it is fabricated with aluminum, the lift offers exceptional corrosion protection. The competitively priced lift can handle a payload of up to 550 pounds, can rise 80 feet per second, and measures 118 x 39 x 24 inches. The ropeguided service lift meets all American and international standards, including the ASME A17.1 – Safety Code for Elevators and Escalators, DIN EN 1808, and applicable health and safety requirements.
ABB has released the S803W-SCL-SR / S800S-SCL-SR self-resetting short-circuit limiter, specifically designed for the wind and other power generation applications. S803WSCL-SR / S800S-SCL-SR is ABB’s innovative self-resetting current limiting module, which considerably increases the short-circuit breaking capacity of downstream manual motor starters or high-performance MCBs (S800). Maximizing system availability and compact for DIN rail mounting, the shortcircuit limiter provides full selectivity for any downstream motor protection combination. In case of a short circuit in one of the end circuits, the S803W-SCL-SR / S800S-SCL-SR helps the downstream means of protection to break the defective circuit without forcing the upstream protection device to trip. In the event of a downstream short circuit, the limiter will react selective to a group of, for example manual motor starters, until the respective faulty motor circuit has tripped. All other motor starters in the group also remain operative. Two versions are available, to address the UL and IEC markets respectively: S803W-SCL-SR available as 3-pole version, acc. to UL508, and IEC 60947-2 and S800SSCL-SR available in 1-, 2-, 3-pole version, according to IEC 60947-2.
The XA Pro has more new features and more content that will make the everyday maintenance at a wind farm a lot easier. One new feature is the Machine Defined Data, which makes it possible to save machine configurations as templates. With the XA Pro alignment tool, data such as all distances, tolerances, and target values for each and every machine, is readily available. Moreover, the GO Pro is a wireless product now available with several useful features, including its unique adaptive user interface, combined with the function Compound Moves. The GO Pro actually recommends how to proceed depending on a measurement result.
