Gill WindSonic 75 Anemometer

WindSonic 75 Anemometer Description

The WindSonic 75 solid-state ultrasonic technology has an increased upper wind speed limit of 75m/s (146 knots) plus all the advantages of the proven Gill WindSonic design. Having no moving parts that can jam, break or wear out makes it the sensor of choice for harsh weather conditions and remote locations when you need to know you can just fit and leave without fear of failure or damage that occurs with traditional cup and vane sensors.

WindSonic 75 comes in three variants and are suitable for a wide range of wind monitoring applications especially when high wind speed accuracy is required, including marine & offshore (ships, data buoys) and land based installations. With a corrosion free polycarbonate construction and no moving parts, this ultrasonic wind sensor eliminates the need for expensive on-site maintenance, particularly in remote locations where access is difficult.

Gill WindSonic 75 comes in three main options:

• WindSonic 75 Option 1: Transmits using RS232 standard communication. Compatible with RPR's SpaceLogger data loggers and the WeatherFile Communication Unit (WCU) for distances less than 20 metres and when the electrical environment is benign.
• WindSonic 75 Option 2: Transmits using RS422/RS485/NMEA communication standards. Compatible with RPR's SpaceLogger data loggers and the WeatherFile Communication Unit (WCU) for distances over 20 metres. For use where there may be heavy duty electrical equipment in operation in the vicinity.
• WindSonic 75 Option 3: Transmits using RS232 or RS422/RS485/NMEA and analogue outputs, used when an analogue output is specifically required. Note if used with our WS15A display output must be set to RS422/485. Analogue output type may be selected from 0-5V, 0-20mA or 4-20mA.

Configuring the WindSonic Sensor:

WindSonic 75 sensors can be configured using the free software provided to select the output rate and units of measurement that suit the application. WindSonic automatically transmits an anemometer status code with each output to indicate its operating status. This ensures accuracy and reliability.

To change the setting of a WindSonic sensor from the default factory settings, it is possible to communicate with the sensor direct from a PC using HyperTerminal (or similar terminal emulation package). Use the WindSonic/GMX D9 Serial Config Cable or the WindSonic/GMX USB Config Cable for easy connection to a PC and power supply.
