Der MetSENS300 ist ein kompakter Wettersensor für Lufttemperatur, relative Luftfeuchte und barometrischen Luftdruck. Die Sensorelemente befinden sich in einem natürlich belüfteten Strahlungsschutz ohne bewegliche Teile. Als Daten können Temperatur, relative und absolute Luftfeuchte, Luftdruck, Luftdichte und Feuchtkugeltemperatur ausgegeben werden. Der MetSENS300 kann SDI-12, RS485, ModbusRS-485 oder NMEA RS-232 ausgeben und ist damit kompatibel mit dem MeteoPV Solar Resource Platform und allen neueren Campbell Datenloggern.

FAQs für

Number of FAQs related to 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.
