WEATHER STATION The MetPak is a compact and lightweight multi-sensor instrument  that  measures  a  wide  range  of  weather parameters. Ultrasonic    technology,    as    used    in    the    proven WindSonic   instrument,   measures   wind speed   and  direction. Temperature  and  humidity  are  measured using  industry  standard  probes  housed  in  a  naturally aspirated   radiation   shield.   Barometric   pressure   is measured within a vented enclosure. The serial  data  output is ideal  for  interfacing with  a WS-15A Display Unit or for data logging to a SpaceLogger®WindLogger. The  MetPak™ weather  station  can  be  supplied  with  digital  SDI-12,  RS232  &  422  outputs.  Low  power consumption enables this weather station instrument to be used in remote locations where power is at a premium. An electrical junction box is fitted to the mounting bracket allowing convenient termination of all electrical cables Wind Speed & Direction Barometric Pressure Temperature Dew Point Humidity Rugged, Professional Design Specifications: Wind Measurement Sensor: WindSonic ultrasonic; Parameters: Polar Wind Speed & Direction or U & V Vectors; Wind Speed:Range: 0-60m/s (134 mph); Accuracy: ± 2% @12m/s; Resolution: 0.01 m/s (0.02 mph); Threshold: 0.01 m/s (0.02 mph);Units: of measure m/s, knots, mph, kph, ft/min Wind Direction: Range: 0 to 359 degrees–no dead band;Accuracy: ± 3° @12m/s;Resolution:1°; Air Temperature: Sensor: Rotronic HygroClip model HC2-S3; Sensor type: Pt100 1/3 Class B; Range:-35°C to +70°C; Accuracy: ± 0.1°C; Resolution: 0.1°C (0.1°F); Units of measure:°C,°F or K; Relative Humidity: Sensor: Rotronic HygroClip model HC2-S3.Compensated for temperaturedependency; Range:0-100% RH; Accuracy:± 0.8% @23°C; Resolution:0.1% RH; Units of measure: % RH Barometric PressureL: Sensor: Solid state device.Compensated for temperature dependency-20°C to +70°C; Range: 600-1100hPa; Accuracy: ±0.5hPa; Resolution: 0.1hPa; Units of measure: hPa, mbar, mmHg, InHg; Dew Point Sensor: Rotronic HygroClip model HC2-S3; Accuracy:± 0.15°C@ 23°C ambient temp, 20°C dew point:Resolution: 0.1°C (0.1°F); Units of measure:°C,°F or K Outputs: Digital outputs: RS232, RS422 or SDI-12; Baud rates: 1200 (SDI-12)–9600-57600 (ASCII RS232, RS422); Protocols: ASCII or SDI-12 V1.3; Data output: 0.25, 0.5, 1 Hz or polled mode MetPak II statusStatus codes provided within the data message string; Mechanical: External construction: UV stabilised white thermoplastic Mounting: Pole Mounting: Gloss white painted aluminium mounting bracket (with mouldedplastic V-block and stainless steel U-bolt), which allows it to beattached to a vertical pipe of any diameter between 25mm and 50mm Weight: 1.1kg (including bracket); Radiation shield: 6-plate, naturally aspirated Power Supply: Supply: voltage: 5V to 30 V dc; Current: <50mA; Environmental: Protection class:IP65; Operating temperature:-35°C to +70 °C; Storage temperature:-40°C to +80 °C: Operating humidity: 0% to 100% humidity; Miscellaneous: Calibration: Factory calibrated Software: MetView-free software providing the means for configuring theMetPak II and reading output data Includes: (1) Gill Instruments MetPak™ Weather Station (1) MetSet configuration software (1) MetView data logging/visualisation software (1) Mounting kit to adapt to poles or masts (1) Selectable ASCII, NMEA, SDI-12 or Modbus Outputs
