Digital weather instrument (ship, wind speed and direction) Model: QDHY-XZC2-2A advantage

1. Main application This instrument is mainly used for various types of ships, offshore oil drilling platforms and ocean port meteorological stations, and provides accurate meteorological data quickly through wired telemetry:
1. Instantaneous synthetic wind speed and instantaneous synthetic wind direction;
2. The average synthetic wind speed of 2 minutes and the average synthetic wind direction of 2 minutes;
3. Instantaneous true wind speed and true wind direction;
4.2 The average true wind speed in 2 minutes and the average true wind direction in 2 minutes;
5. Air temperature and air relative humidity (by looking up the table)
2. Notable features
1. Advanced sensor technology greatly improves the reliability of the instrument;
2. Digital display of multiple measurement data;
3. Enter the ship's speed and course manually;
3. Display terms
1. Synthetic wind speed (wind direction): the wind speed (wind direction) after the superposition of the wind speed (wind direction) of the air and the ship's speed (heading) vector, that is: the instantaneous synthetic wind speed (wind direction) is referred to as the combined wind speed (wind direction)
2. Average wind speed (wind direction): the moving average of the synthetic wind speed (wind direction) in 2 minutes;
3. True Wind Speed ​​(True Wind Direction): The wind speed of the air (wind direction)
4. Average True Wind Speed ​​(True Wind Direction): A sliding average of 2 minutes of true wind speed (True Wind Direction).
Four, technical indicators
1. Wind speed measurement range: 1.0 ～ 70m / s
Accuracy: ± (0.5 + 0.05V) m / s〓 where V——actual wind speed resolution: 0.1m / s
2. Wind direction measurement range: 0 ～ 360 °
Accuracy: ± 5 °
Resolution: 5 °
3. Starting wind speed <1m / s
4. Wind direction non-induction angle: <± 10 ° at 1m / s wind speed

7. Normal working condition of sensor: -30 ° ～ + 50 ℃
Relative humidity: 100% or when there is precipitation
8. Sampling time: 2 seconds
9. The normal working conditions of the monitor: the monitor should be placed in the cabin or indoor, the indoor temperature is 0 ~ +40 ℃, the relative humidity is less than 85%, should pay attention to prevent exposure, rain, wind and dust.
10. power supply:
AC 198V ～ 242V 50Hz
Power consumption <10W
