概述

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 theMeteoPV Solar Resource Platformand any Campbell Scientific data logger using SDI-12, RS-485, ModbusRS-485, or NMEA RS-232.

频繁的ly Asked Questions

Number of FAQs related toMETSENS300:1

  1. What are some distinguishing features of the MetSENS compact weather sensors?
    • 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.
    • 梅森拥有两年的使用寿命，特别是使用双百叶窗的辐射屏蔽特别有助于降低污染物的流动，从而进入温度/湿度探头。
    • 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.
    • 如果温度下降或发生雨发生，则梅森并未表示风速下降，而这在其他全天候传感器中相当常见。
