The advantages of the combination are high EMC protection, large guiding distance tolerance, and a superior signal performance up to 327,680 pulses/360°. The incremental, non-contact, Posirot measuring system PMIS4/PMIR5 consists of the sensor head PMIS4 and an incremental magnetic…

The ATS Current Sensing Switch and Transducer is a one piece solution that combines a limit alarm with an analog output signal transducer to monitor produced or consumed ac current up to 1,200A, while magnetically isolating outputs and inputs to maximize safety. The innovative and patent-pending rotary switch makes it easy for users to set…

  The Positape series of sensors exceeds expectations when used in areas of difficult access and where pulley wheels change the direction of a tape route. On conventional draw-wire sensors, these pulleys can reduce the life of the draw wire. The stainless stell Positape measurement tape, however, will have at least twice the life of…

A manufacturer of inductive components has expanded its line. Premo’s TP0702 provides up to 50 mV/Apk-pk/m (for 7.2 mH) sensitivity, which gives it the best sensitivity in this transponder size, the company says. The TP0702U and TP0702UCAP is an SMD antenna for low frequency 20-150 kHz receiver applications. TP0702UCAP provide an upper and lateral side…

More than 5 millions hours – or 570 years – of wind data has been recorded by Second Wind’s Triton Sonic Wind Profiler since its launch in 2008. The company says no other remote sensing tool has amassed as much data. The milestone was reached around the time of AWEA Windpower 2012 conference, Second Wind’s…

A sensor manufacturer has expanded its product line of tape-extension position sensors, POSITAPE with the introduction of the WB25 series. The family was developed for applications that require the use of cable pulleys due space limitations. The measurement ranges of the WB25 series are 12m, 15m, 20m and 25m all in compact housings. The flexible…

A set of three blades with active surfaces and sensors will allow writing controls that tailor blade shape to wind conditions, and ideally capture more energy than conventional designs. By:  Christian Fritz, Senior Product Manager for Advance Machine Control at National Instruments, www.Ni.com Dale Berg Staff, Wind Energy Technologies Department at Sandia National Laboratories, www.sandia.gov With a power generation capacity of…

Triton is a sonar-based wind sensor for measuring speed and direction at hub height and higher. Equipment users at a recent AWEA Wind Resource and Project Energy Assessment workshop learned about remote sensing research and the latest product developments — and gave feedback to developer Second Wind on the ways they are using the sensors…

The 2000 series SoDARs are intended as high-altitude sensors. These use three parabolic dishes in three separate enclosures. The 2000 series can operate in lower power consumption mode, pulsing each antenna at different time intervals. Or, they can be configured to sample all three beams simultaneously, increasing the number of complete samples during the averaging…

The DT Series Large Aperture Current Transducers combines a hall effect sensor and signal conditioner into a single package for use in dc-current applications up to 1,200 amps. Factory calibrated ranges simplify operation and eliminate zero and span pots. Industry standard 4 to 20 mA, 0 to 5 Vdc or 0 to 10 Vdc outputs…

Wind farms run on sensors. They make condition monitoring and SCADA systems possible. Without sensors, no system can be controlled. One pearl of wisdom often dropped by control engineers says that a control is only as good as what it measures, and an event cannot be controlled if it cannot be measured. For wind professionals,…

ZephIR 300 wind lidar, remote sensing for U.S. wind energy market, will be available in the U.S. through Campbell Scientific. The wind sensor is said to provide accurate wind data across all stages of a wind farm project. Manufactured by Zephir Ltd. of the UK, a subsidiary of renewable energy group Natural Power, the ZephIR…

Pepperl+Fuchs has introduced edition 1.0 of the company’s North American Sensor Catalog and Selection Guide. This nearly 1,200-page resource details the company’s family of capacitive, inductive, weld immune, special application, NAMUR, ultrasonic, and photoelectric sensors. It also details the company’s rotary encoders, cordsets, special function devices, and accessories. Complete product specifications, benefits, and ordering information…

The Magnetocode (MCD) absolute rotary encoders feature reliability, accuracy, and adaptability. Now, a new hollow-shaft version of the MCD encoder makes it easy to mount these devices on shafts up to 20-mm dia. The recent devices are available with analog (voltage/current) or digital electrical interfaces. Analog versions are a substitute for traditional potentiometers, offering superior…

The continuous shortage of Hall Effect sensors is trouble for manufacturers. But Premo’s family of Hall effect sensors have an output current with a fixed range of 4 to 20mA. The new series provides a linearity <0.5% with a ±1% accuracy levels. The bandwidth is up to 6kHz with a response time less than 200…

For speed and position monitoring on large diameter shafts, manufacturer Baumer introduces the HDMag line of high-precision, bearing-less, and contact-free magnetic tape encoders. Replacing expensive and complicated specialized solutions that require belts, gears, couplings, and linkages, the HDMag series of encoders is easy to install and will direct mount onto almost any large-shaft torque motor…

Hoarfrost, ice, and storms are frequent winter events in the Sternwald Forest at a thousand meters above mean sea level and on the border between Austria and the Czech Republic. Despite this, seven wind turbines faithfully work there without unnecessary downtime. Credit for this success goes to a BLADEcontrol system, built by the IGUS ITS…

Because of the remote location of many wind turbines, sensors serve as critical components in their operation, maintenance, and safety. Pressure sensors monitor yaw brake, lubrication oil, cooling circuit pressure, and level in gear boxes. Differential-pressure sensors monitor filter conditions. As a hydraulic filter clogs, its output signal increases, notifying the controller to replace the…

A line of rugged encoders has added a heavy duty, incremental, shafted version to deliver superior reliability in tough wind generator, steel, and paper applications. The HD35R, made by Dynapar in the U.S., will feature a 10-day lead time, and will be an excellent alternative to the Hubner POG90, according to the company. A few…
