MSO Weather Sensor

Wind Speed and Wind Direction are measured using conventional cup and vane techniques. All other measurements are housed in a multi-plate naturally aspirated radiation shield to reduce solar radiation errors. The shield is constructed of a series of concentric white aluminum plates, which allow air to flow through the shield, while blocking direct solar rays.

The temperature sensor is a platinum RTD class 1/3B. relative humidity is a based on our very accurate solid state sensor designed for continuous exposure to adverse climates. The barometric pressure sensor is a piezo-resistive device designed for robustness, high accuracy needs, as well as long term stability.

Digital outputs are presented as a data stream every second, or upon command by data system.

Options:

  • 10600 USB and power interface.
  • WMO compliant external tipping bucket rain gauge connects simply and allows for correct installation and siting per industry guidelines.
  • Solar radiation sensors are connected easily and integrate seamlessly into the SWS data record.
