Overview

The MetSENS500 compact weather sensor measures wind speed and direction via an ultrasonic sensor, as well as 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. An integrated electronic compass allows the MetSENS500 to provide accurate, relative wind direction measurements without being oriented in a particular way, making installation easier. WMO average wind speed and direction and gust, temperature, relative humidity, barometric pressure, absolute humidity, air density, and wet bulb temperature data are provided. The MetSENS500 is compatible and easily integrated with the米eteoPV Solar Resource Platformand any Campbell Scientific data logger using SDI-12, RS-485, ModbusRS-485, or NMEA RS-232.

Frequently Asked Questions

Number of FAQs related to米ETSENS500:1

  1. What are some distinguishing features of the MetSENS compact weather sensors?
    • 米etSENS 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.
    • 米etSENS 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.
    • 米etSENS has an option for GPS.
    • 米etSENS has a wind speed resolution of 0.01 m/s, whereas most all-weather sensors have a resolution of 0.1 m/s.
    • 米etSENS has a dew point accuracy of ± 0.3°C, whereas most all-weather sensors have an accuracy of > ±0.7°C.
    • 米etSENS temperature resolution is for the full-range temperature at 0.1°C, whereas other all-weather sensors change to 0.2° at the extremes.
    • 米etSENS offers users the option to use any industry-standard tipping bucket rain gage (MetSENS550).
    • 米etSENS provides RS-232, RS-485, Modbus, and SDI-12 from all models.
    • 米etSENS uses Intelligent Signal Processing (ISP) and Adaptive Gain Control (AGC), which have been proven worldwide to provide good quality data.
    • 米etSENS 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.
