IEC 61724-1 Compliant
概览
The MetSens300 compact weather sensor measures air temperature, relative humidity, and barometric pressure in a single, combined instrument mounted inside three double-louvered, naturally aspirated radiation shields with no moving parts. Temperature, relative humidity, barometric pressure, absolute humidity, air density, and wet bulb temperature data are provided. The MetSens300 is compatible and easily integrated with the MeteoPV Solar Resource Platform and any Campbell Scientific data logger using SDI-12, RS-485, ModbusRS-485, or NMEA RS-232.

MetSens300 Example Programs v.1 (4 KB) 25-09-2019
Three CR1000X data logger programs that read the MetSens300 measurements and sensor status. An example program is included for each output option (RS-232, Modbus, SDI-12).
常见问题解答
MetSens300: 1
-
- MetSens has a compass module that outputs at 1 Hz real time without affecting any other measurements, which allows the correction of wind direction if the station is installed on moving ice.
- MetSens has a two-year service life, which is especially helped by the use of a double-louvered radiation shield to reduce the flow of contaminants getting to the temperature/humidity probe.
- MetSens has an option for GPS.
- MetSens has a wind speed resolution of 0.01 m/s, whereas most all-weather sensors have a resolution of 0.1 m/s.
- MetSens has a dew point accuracy of ± 0.3°C, whereas most all-weather sensors have an accuracy of > ±0.7°C.
- MetSens temperature resolution is for the full-range temperature at 0.1°C, whereas other all-weather sensors change to 0.2° at the extremes.
- MetSens offers users the option to use any industry-standard tipping bucket rain gage (MetSens550).
- MetSens provides RS-232, RS-485, Modbus, and SDI-12 from all models.
- MetSens uses Intelligent Signal Processing (ISP) and Adaptive Gain Control (AGC), which have been proven worldwide to provide good quality data.
- MetSens does not indicate a drop in wind speed if the temperature drops or if rain occurs, whereas this is fairly common in other all-weather sensors.
