WindSonic Two-Dimensional Sonic Anemometer

5. Overview

The WindSonic is an ultrasonic anemometer for measuring wind direction and
wind speed. It uses two pairs of orthogonally oriented transducers to sense
horizontal wind. The transducers bounce the ultrasonic signal from a hood,
minimizing the effects of transducer shadowing and flow distortion.

Detailed information on the Gill WindSonic is available in the manual
published by Gill Instruments, Ltd. and can be found at

www.gill.co.uk/products/anemometer/windsonic.htm

. This manual serves as a

guide for interfacing the WindSonic to Campbell Scientific dataloggers. The
WindSonic is available in two versions. Option 1 WindSonic (WindSonic1)
outputs data using the RS-232 interface. Option 4 WindSonic (WindSonic4)
outputs data using the SDI-12 interface.

The WindSonic1 connects to the control/serial ports (COMn) of a CR800-
series, CR1000, or CR3000 datalogger. Two control ports make a COMn
serial port; for example, Port 1 and 2 are COM1

.

A maximum of four

WindSonic1 anemometers can be connected to a single CR1000 or CR3000
datalogger, while two can be connected to the CR800-series control ports
(COMn). Additional WindSonic1 anemometers can be interfaced using the
SDM-SIO1. Campbell Scientific does not recommend using the CR200(X)-
series, CR5000, or any of the Edlog dataloggers with the WindSonic1 because
of their limited serial support using the control ports.

Campbell Scientific recommends that the WindSonic4, SDI-12 interface, be
used with CR200(X)-series, CR510, CR10X, CR23X, or CR5000 dataloggers.
SDI-12 is a three-wire digital interface standard used by processor-based
sensors and digital recording devices. The CR800-series, CR1000, and
CR3000 dataloggers also support the SDI-12 interface.

The WindSonic includes a user-specified cable to interface to a Campbell
Scientific datalogger. The WindSonic’s cable can terminate in:

• Pigtails that connect directly to a Campbell Scientific datalogger

(option ─PT).

• Connector that attaches to a prewired enclosure (option ─PW). Refer

to

www.campbellsci.com/prewired-enclosures

for more information.

A serial cable (WINDSONICRCBL-L) is available for interfacing a
WindSonic1 or WindSonic4 to a PC running Gill’s PC support software. The
cable and software are used during troubleshooting or to change settings in the
WindSonic1 for a specific application. A copy of Gill’s PC support software is
available at

www.gill.co.uk/main/software.html

. WindView is used for

WindSonics with serial numbers of 0810001 or greater, and WindCom is used
for WindSonics with serial numbers that are less than 0810001.
