Wind Turbine Assessment Wind turbines and towers utilize literally thousands of fasteners. Selecting the proper tools and applying the correct amount of torque to each fastener is imperative for optimizing the costs of operation. RS Technologies, a division of PCB Load & Torque, Inc., serves the product assembly and fastener manufacturing communities with a complete line of rotary and stationary torque sensors, hand torque wrenches, measuring instruments and threaded fastener torque-tension testing systems. For more information on any of these products, please visit www.pcbloadtorque.com....

Wind Turbine Assessment Microphones & Preamplifiers - Energy & Power Generation Microphones are used to measure the noise from the wind turbine both internally and externally. The gearbox and the main bearing are typical noise sources which should be measured internally, while the overall turbine noise is monitored externally. Larson Davis, a division of PCB Piezotronics, manufactures various Sound Level Meters and Microphones which can be used to make these different types of acoustic measurements. By utilizing the built-in narrow band FFT analysis option on Model 831, higher frequency...

Wind Turbine Assessment Instrumentation that can provide voltage excitation and bridge completion is ideal for this measurement. Strain gages can be placed anywhere on the blade, but the distribution varies with the amount of sensors. These sensors should be in a configuration to optimally model the stress on the blade, taking measurements from both the flapwise and edge-wise directions. Load, Strain & Torque - Energy & Power Generation ICP® Strain Sensor Model RHM240A02 n Measure Longitudinal Strain on Machinery Structures Monitor Quality, Safety and Reliability Robust Construction Endures...

Wind Turbine Assessment Single Channel Telemetry Systems Energy & Power Generation PCB Load & Torque, Inc. single channel telemetry systems provide a simple, accurate method of conditioning and transmitting strain signals on rotating or moving machinery while operating in a completely contactless mode. Power is transferred inductively and the signal is RF- transferred between the moving and static component - no brushes or wires required. This method guarantees an absolute maintenance- free continuous operation and accurate transmission of measured data. Series 8180 performs a remote shunt...

Wind Turbine Assessment Test engineers have used the principles of modal analysis, using PCB Piezotronics, Inc. ICP® accelerometers, Modally Tuned® Impulse Hammers and ICP® quartz force sensors to determine the strength and structural integrity. Single-axis and triaxial MEMS DC accelerometers are placed on the tip of each blade. The photo on page 9 shows a wind turbine blade mounting in a dynamically controlled, hydraulic structural loading machine, along with the various sensors and cables mounted on the blade. Modal Shakers & Hammers - Energy & Power Generation ICP® Impact Hammer Model...

Wind Turbine Assessment MEMS DC Response - Energy & Power Generation Single-axis MEMS DC Accelerometer Series 3711 (singe-axis), 3713 (triaxial) and 3741(single-axis) MEMS DC response accelerometers are designed to measure low frequency vibration and motion and are offered in full-scale ranges from ± 2 to ± 200 g to accommodate a variety of testing requirements. The units feature gas-damped, silicon MEMS sensing elements for uniform, repeatable performance and offer high frequency overload protection. Electrically, the units offer a single ended or differential output signal with power,...
