1405-PK-040 Gill WindSonic Ultrasonic Anemometer, RS 232, RS485, RS422 RS 232, RS485, RS422 + 0-5V or 4-20ma Outputs

A lightweight unit, the WindSonic Ultrasonic Anemometer, manufactured by Gill Instruments, is of a robust, high strength construction. Without the need for expensive on-site calibration or maintenance, and with a corrosion free exterior, WindSonic is a true fit and forget unit.

The flexible design enables you easily to configure WindSonic to deliver the information you require. By using the software provided it is possible to select the output rate and choose the units of measurement that suit your application. Ensuring accuracy and reliability, WindSonic automatically transmits an anemometer status code with each output to indicate its operating status. Available in several options, providing a number of different digital and analog outputs, WindSonic is supplied with NMEA and RS232 digital output as standard.

Maintenance free, quick and easy to install, WindSonic is designed to be mounted using a standard pole fitting and comes complete with all screw fittings, a mating marine grade connector, and comprehensive user manual.

Providing accurate results in all weather conditions, WindSonic exhibits a number of distinct advantages:
  • Consistent performance throughout life (no accuracy degradation due to wear of moving parts)
  • Corrosion free, UV resistant material
  • Low start speed (0.01 m/s, 0.09 knots)
  • Maintenance free
  • No calibration required
  • Robust construction
  • Software configurable
  • Status code output
  • True 0-359 operation (no dead band on direction output)
  • Wind speed and direction from a single unit
  • Includes 50' of cable and connector
