WindSonic 75

Wind Speed & Direction Sensor

The Gill WindSonic is a low-cost  anemometer, which utilises Gill’s Utrasonic technology to provide wind speed and direction data via one serial or two analogue outputs. To confirm correct operation, outputs are transmitted together with an instrument status code. With a robust, corrosion-free polycarbonate housing, this small, lightweight wind sensor is recommended for use in harsh environmental conditions and is particularly suited to marine & offshore (ships, data buoys) and land based installations. The WindSonic has no moving parts, offering maintenance-free operation in a wide range of applications.

WindSonic M Ultrasonic Wind Sensor

WindSonic M

has been designed to comply with all the applicable sections of BS EN 60945 standard for 'exposed equipment'. These include but are not limited to; corrosion (salt mist), vibration, radiated and conducted emissions and water ingress. In addition the unit has been designed to withstand hail or falling ice to UL 2218 Class 1.

WindSonic M provides a marine-standard NMEA 0183 output, with options for RS232, 422, 485 and analogue outputs also available to ensure compatibility with most systems. A single connector and three mounting holes for attachment to a 1.75" pipe ensure installation is straightforward. With no moving parts to wear out and no routine calibration required, WindSonic M has a very low maintenance overhead.

This sensor is recommended for use in harsh environmental industrial conditions and is particularly suited to marine and land based installations (optional heating).

The WindMaster RA 3D sonic

The WindMaster RA (right angled) 3D sonic anemometer

For monitor wind speeds of 0-50m/s (0-100mph), providing users with data via digital outputs for U, V, and W vectors as standard.

Outputs are also provided for Speed of Sound and Sonic Temperature are available as standard.

The lightweight WindMaster RA is constructed from aluminium and carbon fibre and is available with either a 20Hz or optional 32 Hz data output rate. Optional analogue inputs and outputs are available with either 12 or 14 bit resolution.

The WindMaster RA (right angled) 3D sonic anemometer offers an alternative head design where an omni-directional measurement concept is desired while minimising any mechanical influence in the vertical wind plane to provide users with the least disturbed wind measurement for non-stationary measurement applications with a known predominant wind direction. (tethered balloons, land vehicles, marine vessels, etc…)

Heated Anemometer - WindObserver 75

The WindObserver 75 has been developed for measuring higher wind speeds in extreme weather environments featuring 150 Watts of electrical heating power in the anemometer head. This anemometer has been designed to remain ice free in most freezing weather conditions. The sensor provides data via RS422/RS485 bidirectional link, which allows several units to be networked together and data logged on demand.

With innovative transducer design, this anemometer boasts a very high wind speed range of 0 - 75 m/s (0-168mph) and gives an output status indicating the validity of data, so that you can be confident that the instrument is providing accurate information. With an IP66 rated stainless steel construction, this anemometer meets the stringent performance criteria specified by wind turbine manufacturers, airports, marine, oil and gas production, and meteorological organisations around the world.

HS-100 Horizontal-Head

The HS-100 3-axis anemometer 

features a horizontal head design, which allows for accurate measurement of vertical flows with minimum flow interruption from the anemometer geometry.

Ideal for scientific research applications, HS-100 is capable of monitoring wind speeds of 0-45m/s and offers a fast update rate of 100Hz for precision wind analysis.

The head of the anemometer features a built-in inclinometer to allow the instrument to be accurately positioned on a tower or mast. Access to the PRT and analogue inputs is provided via a separate electronic enclosure. The instrument is ideal for analysis of surface turbulence and can be positioned close to the ground or crop and tree canopies.
