3 The WL12 is a long range wireless anemometer and data logger. The WL12 anemometer measures wind speed and direction. The display unit connects to the anemometer via its own 868 MHZ radio and can transmit up to 250m (line of sight). The WL12 also logs all readings on an SD card in the display unit. This data can then be analysed post event for time stamped wind ratings. You can view current, average & maximum wind speed, wind direction and temperature from the display unit. Functions: - Current wind speed - Wind direction - Temperature - 24h wind speed, wind direction and temperature history graphs - 7 days history of maximum and average wind speed on display unit - Logging of all readings on internal SD Card - Date and time stamp on readings Features: - Easy-to-use solution for wind site evaluation - Easy installation without running cables - Range up to 250m [Line of Sight] (up to 1000m with external antenna and extended range sensor. Please contact us for details.) - Up to 1 year battery life - Display unit can be battery or external powered - Built-in battery back-up real time clock - Large illuminated LCD display Data Logger: - Average and maximum wind speed at user selected intervals - Average wind direction - Temperature - Date and time stamp of each reading Applications: - Wind and temperature monitoring for spraying conditions - Wind monitoring on-site at events - Crane applications: - Mobile cranes - Tower cranes - Bridge cranes - Construction Sites - Data logging of wind (site survey) Logging: average and maximum wind speed, wind direction, temperature Logging interval: selectable: 10sec, 1min, 10min, 60min Data recording: up to 12 months, .txt data format Memory card: micro SD (included) Wind speed measurement range: 0.6 m/s - 50.0 m/s Wind speed resolution: 0.1 m/s Wind speed accuracy: +/- 2.5%, calibration possible in 0.5% steps Wind speed units: m/s, km/h, knots, mph Wind direction measurement range: 0 - 359 Wind direction resolution: 1 Wind direction accuracy: +/- 2.5, adjustable offset +/- 180 Temperature measurement/operating range: -25C to +60 C Temperature resolution: 1 C Temperature accuracy: +/- 1C, calibration possible in 0.5 C steps Temperature units: C, F Communication frequency: 868MHZ Antenna Input:50 Ohm, SMA connector Data transmission rate: every 2 seconds Range: Internal antenna and standard range sensor - up to 250m visible distance (Line of Sight) [Optional Extra] External SMA antenna and extended range sensor - up to 1000m visible distance (Line of Sight) Battery: 4 x 1,5 V AA battery (not included) Battery life: up to 12 months (without display illumination) External power supply: 5V DC, micro USB (adapter is not included) Bearings: Precision stainless steel ball bearing Material - housing: - Aluminium / PVC - cups (replaceable): PA (NYLON) - vane (replaceable): Carbon Dimensions - WSD sensor: - Height 250 mm - overall vane diameter 220 mm - cup to cup 120 mm Dimensions - Display Unit: ABS, 115 x 83 x 32 mm Mounting: Mounts on a pipe with 20 mm diameter Wind tunnel certification available.
