WXT 532

Range : Wind speed, Wind direction

Vaisala Weather Transmitter WXT530 series is a unique collection of cost-effective sensors that accurately and reliably measure weather conditions. They can capture any combination of wind, rain, temperature, and barometric readings in a compact, affordable package.

WXT530 models utilize solid state technologies that minimize operating and maintenance costs. Digital and analog interfaces make for easy, flexible integration, and third-party sensors can be connected to select WXT530 models to create your own weather parameter hub.

Applications

  • WXT530 models utilize solid state technologies that minimize operating and maintenance costs.
  • The WXT532 focusing on the wind speed, and wind direction.
  • Low power consumption is ideal for battery powered systems.

Features

  • Unique Vaisala solid state sensor technology that includes WINDCAP®
    ultrasonic wind sensors to determine horizontal wind speed and direction.
  • Wide variety of digital communication modes for easy integration with
    most weather monitoring platforms.
  • Self-diagnostics automatically validate measurement stability.
  • Optional thermostatically controlled heaters in the transducer heads and
    arms prevent build-up of freezing rain and snow for operation in cold and
    humid environments.
