| 温室气体通量监测与气象保障系统旨在构建一个完整的、科研级的野外观测系统，所有设备选型均以满足涡度协方差法等高精度通量监测需求为标准，具体包含三维超声风速仪2个，200WX WeatherStationR Instrument 2个，供电系统一套，3-5M观测塔一套、高频数据采集器一套、通量数据处理软件、数据通信系统、数据显示系统、安装与调试服务。 1、三维超声风速仪由三组探头组成， 每一组探头中的两个探头都要在其轴向上交替发射 声音信号并接收对面探头的脉冲信号。由于探头轴 向上的风速分量的影响，使声音到达接收器的时间 随风速而变化。三维超声风速仪便利用探头之间的 距离以及两次脉冲信号传播的时间差来实现对风速的全方位观测。准确的局地实时风数据，对于提高温室气体排放反演模型精度、减少结果不确定性起到非常重要的作用。 U, V, W轴输出 32Hz输出频率 0-65m/s风速范围 0-359° 风向范围 声温输出 不锈钢材质 可选定制校准 2、200WX WeatherStationR Instrument Ultrasonic measurement of apparent and Dynamic true wind speed and direction Barometric pressure Air and wind chill temperature Relative humidity (field serviceable option) Calculated dew point and heat index GPS position, speed over ground, and course over ground Three-axis, solid-state compass with dynamic stabilization Three-axis rate gyro supplies rate-of–turn data Three-axis accelerometer for best-in-class pitch and roll information Housing IPX6 rated for water-ingress protection Data output via a single cable (various lengths available) NMEA 0183/ASCII serial data protocol over RS-232 interface NMEA 2000 protocol over CAN Relative humidity module Enables dew-point and heat-index calculations Recommend Use: Marine or Land-Based, Mobile or Stationary Humidity: Optional Power Supply Voltage: 9 to 40 VDC Power Supply Current: <75 mA (<0.9 W) at 12 VDC Communications Available Protocol: Comma delimited ASCII, NMEA 0183, NMEA 2000 Waterproof Rating: IPX6 (Relative Humidity/IPX4) Air Temp Accuracy: ±1.1°C at 20°C Air Temp Range: -40 to 80°C (-40 to 176°F) Air Temp Resolution: 0.1°C Apparent Wind Speed Angle: Yes Barometric Pressure Accuracy: ±0.5 hPa at 25°C (or better) Barometric Pressure Range: 300 to 1100 hPa Barometric Pressure Resolution: 0.1 hPa Certs And Standards: CE, IPX6 (IPX4 with optional Relative Humidity sensor), RoHS, IEC61000-4-2, IEC60945, IEC60950_1C, IEC60950_22A, EN55022, EN55024, EN14982 Communications Available Hardware Interface: Serial RS-232, Serial RS-422, CAN Communications Serial Output Rate: 1 Hz typical.
