We offer a variety of products that can be used to create systems for Wind Energy. Many of the major components used to create these systems are listed below. Please let us know if we can help you configure a system.
Our dataloggers can be used for many different purposes. They can make and record measurements, control electrical devices, or both. The dataloggers' multifaceted capabilities include functioning as PLCs or RTUs. They have many different channel types, allowing nearly all sensor types to be measured on a single unit. For example, one datalogger can measure strain on turbine blades, wind speed, and power output of the turbine, even while controlling peripheral devices. The CR1000 with an LLAC4 peripheral can measure up to 10 low-level ac output anemometers. If long cable runs are being avoided, our CR200X-series dataloggers can be deployed in a wireless network configuration, allowing cost effective monitoring at each level of a wind assessment tower.
The reliability of our datalogger systems ensures data collection, even under adverse conditions. Wide operating temperature ranges and weather-proof enclosures allow our systems to operate reliably in harsh environments. Because they have their own power supply (batteries, solar panels), our dataloggers continue to measure and store data and perform control during power outages. Up to 2 million data points can be stored in the datalogger's non-volatile memory, while CompactFlash cards can be used to increase data storage to tens of millions of points. Data is time- and date-stamped to provide key information for identifying and analyzing past events.
Channel types include analog (single-ended and differential), pulse, switched excitation, and digital. Not only are there multiple types of input channels, but each of these channels can be independently programmed for various sensor types. Most sensors connect directly to the datalogger, eliminating the need for external signal conditioning. Multiplexers and other peripherals can be used with most of our dataloggers to increase the numbers and types of channels.
The ability of our dataloggers to perform advanced control functions is a great advantage. Powerful on-board instruction sets allow unattended measurement and control decisions based on time or conditional events. Using these instruction sets, dataloggers can be programmed to perform multiple control functions based on different scenarios. For example, alarms can be triggered, phone numbers dialed, or equipment shut down if the system detects an equipment failure--all without human intervention.
Almost any sensor can be measured by our dataloggers, allowing the wind energy system to be customized for each application. Typical sensors include, but are not limited to: sonic anemometers, 3-cup and propeller anemometers, wind vanes, temperature sensors (air, water, equipment, and product), solar radiation, electrical current, resistance, power, and voltage.
The availability of multiple telecommunications and on-site options for retrieving data or reporting site conditions also allows our systems to be customized to meet exact needs. Options include: radio, telephone, cellphone, voice-synthesized phone, satellite, and Ethernet. Systems can be programmed to send alarms or report site conditions by calling out to computers, phones, radios, and pagers.
Our PC-based support software simplifies the entire data acquisition process, from programming to data retrieval to data display and analysis. Our software automatically manages data retrieval from networks or single stations. Robust error-checking ensures data integrity. We can even help you post your data to the Internet.

After installing the mounting pipe, place the orientation ring, followed by the wind sensor, on the mounting pipe. Orient the junction box to the south, and tighten the band clamps on the orientation ring and mounting post. Final sensor orientation is done after the datalogger has been programmed to measure wind direction as described in Appendix A of the instruction manual.
Campbell Scientific does not sell an extension cable. A replacement cable can be ordered and built to the desired length (pn 05106CBL-L). This replacement cable has a connector that mates with the connector at the end of the 3 ft cable attached to the 05106-L.
The short answer is less than 0.01 mA. The wind speed signal requires no power. The wind direction portion of the sensor only uses a maximum of 0.5 mA when excited with 5 Vdc, and then it is only on for 0.016 s for every measurement. When the wind direction is measured every second (typical), the average current drain is less than 0.01 mA.
