WindSensor P2546-OPR Anemometer The WindSensor P2546-OPR anemometer combines class 1 performance with unrivaled durability. Originally designed for marine environments, the P2546-OPR is ideally suited for wind resource assessment and power performance studies both onshore and off. RNRG offers two versions of the P2546-OPR sensor: the P2546C-OPR (coil version) and the P2546A-OPR (reed switch). Both versions of the sensor are fully compatible with all Symphonie series data loggers. You will need to use Signal Conditioning Modules (SCM) when connecting more than six anemometers to a SymphoniePLUS®3 Data Logger; please see the table below for details. These sensors can also be integrated seamlessly with our NOW Systems.

Wind direction data is an important component of any wind or solar resource assessment campaign, and it is also vital for power performance tests and site monitoring once a project is operational. RNRG offers both heated and unheated wind direction vanes, ensuring access to reliable wind direction data regardless of environmental conditions. NRG 200M Wind Vane NRG Systems’ 200M Wind Direction Vane brings significant upgrades to the proven design of our 200P Wind Direction Vane. NEW IN THE 200M No Dead Band: The 200M has 360° continuous measurement, whereas the 200P has an 8° max. dead band centered on 0°. Reduced Sensor Uncertainty: The 200M's sensor uncertainty is ±1.6° across virtually its full range, whereas the 200P's sensor uncertainty outside the dead band region is ±4.3°. Improved Vane Orientation Precision and Repeatability: The 200M's improved mounting system makes it easier to precisely determine sensor orientation once installed on a boom. Firmer Mounting Connection: The 200M's new mounting system enables a firmer connection between the vane and mounting boom, making it less likely that vane orientation will drift over time. Improved Protection Against Water and Dust Ingress: The 200M's bearing and electronics capsules are fully sealed against water and dust ingress, making it less likely that corrosion or dust will damage the sensor over time. Transparent Records of Sensor Response and Quality: Factory calibration certificates with sensor-specific scale and offset values will be available at no extra cost. Download Calibration Report   MAINTAINED FROM THE 200P Proven Aerodynamic Performance and Robustness: The 200M utilizes the same black, UV-stabilized injection molded plastic vane wing and sensor body that the 200P has been proving in the field for decades. Easy Sensor Traceability: Individual unit serialization makes it easier to keep track of your wind vane's unique history and ties it to its sensor-specific slope and offset values determined during the manufacturing process or in a wind tunnel. Easy Compatibility: The 200M’s simple voltage output is compatible with all industry-standard data loggers, including legacy NRG loggers, and is designed to work seamlessly with the NRG SymphoniePRO® Data Logger. Low Power Draw: With a current draw of 0.9° to 0.9° to

Delta Sunshine SPN1 Pyranometer The SPN1 Sunshine Pyranometer is a meteorological class solar radiation measurement instrument with a built-in heater, and is designed for long-term outdoor exposure.   Overall accuracy: Global (Total) and Diffuse radiation ± 5% Daily Integrals± 5% ± 10 W.m-2 Hourly averages± 8% ± 10 W.m-2 Individual readingsAccuracy figures give 95% confidence limits, i.e. 95% of individual readings will be within stated limits under normal climactic conditions. Details Measures solar radiation and sunshine duration Global (Total) and Diffuse irradiance in W.m-2 DNI (Direct-Normal Irradiance) calculation WMO sunshine threshold: 120 W.m-2 direct beam No moving parts, shade rings or motorised tracking No routine adjustment or polar alignment Works at any latitude Precision ground glass dome The SPN1 Sunshine Pyranometer is a meteorological class solar radiation measurement instrument with a built-in heater, and is designed for long-term outdoor exposure. It is an affordable and effective alternative to shade-ring pyranometers, pyrheliometers and traditional sunshine recorders. The SPN1 Sunshine Pyranometer is exceptionally easy to use; it needs no routine adjustment or polar alignment and works at any latitude. The SPN1 Sunshine Pyranometer is protected by patents EP 1012633 and US 6417500. An internal heater keeps the pyranometer dome clear of dew, ice and snow down to -20°C (in still air conditions), ensuring reliable readings in difficult climatic conditions.   Direct and Diffuse Radiation The SPN1 Sunshine Pyranometer uses an array of seven miniature thermopile sensors and a computer-generated shading pattern to measure the direct and diffuse components of incident solar radiation. The SPN1 Pyranometer computes direct radiation by subtracting the diffuse from the global (total) radiation.     Sunshine Duration The WMO threshold for bright sunshine is 120 W.m-2 in a plane perpendicular to the direct solar beam. The SPN1 Pyranometer uses an algorithm based on the ratio of direct to diffuse radiation, combined with their absolute values, to estimate sunshine duration to within a few percent of the WMO standard. The SPN1 Sunshine Pyranometer does not need to be adjusted or repositioned to track the sun - a distinct advantage over devices with shadow rings. There are no complex electro-mechanical assemblies and no burnt paper tracks to interpret.     Outputs and Logging The SPN1 Sunshine Pyranometer provides 2 analogue voltage outputs for global and diffuse radiation, and a digital output for sunshine duration, which can be connected to data loggers, such as the Delta-T Devices DL2e and the compact GP1. Readings can also be obtained directly from the RS232 port and viewed/logged using the SunData software supplied.

RNRG 200P Wind Vane The 200P Wind Vane is one of the most widely used wind direction sensors in wind, solar, and meteorological applications worldwide.   Constructed of thermoplastic and stainless steel components, the 200P resists corrosion and features a high strength-to-weight ratio. The 200P is directly connected to a precision conductive plastic potentiometer located in the main body. When a constant DC excitation voltage is applied to the potentiometer, it produces an analog voltage output directly proportional to the wind direction. The 200P includes a PVC terminal boot for additional protection from the elements.  

RNRG IceFree3 Heated Vane The heated IceFree3 Vane is a proven and reliable solution for measuring wind direction in icing environments.   The IceFree3 Heated Vane’s head is directly connected to a 10K ohms conductive plastic potentiometer located in the main body. When a constant DC excitation voltage is applied to the potentiometer, it produces an analog voltage output directly proportional to the wind direction. The sensor’s potentiometer linearity is within 1 percent of wind direction, ensuring precise measurements. The signal output is an analog DC voltage. The internal heater is powered by 24 VAC and allows for an operating temperature range of -40°C to 80°C (-40 °F to 176 °F). The optional 120/240 VAC to 24 VAC Transformer - IceFree3 Sensors is available to step down 120/240 VAC grid power. The IceFree3 Heated Vane comes with an 8 m potted cable that can be extended to your desired length using Power Cable Kit - IceFree3 Sensor 3C, sold separately and available in 10 meter increments up to 90 meters.

The electrically heated IceFree3 Anemometer's simple, robust design provides a proven and reliable solution in icing environments. The IceFree3 signal output is a variable amplitude sine wave, where frequency is proportional to wind speed. Patented off-axis correction minimizes errors in measuring up-slope or down-slope winds.
