EIT designed and installed weather monitoring equipment for the Sydney Harbour Bridge, BridgeClimb tour (www.bridgeclimb.com). Weather monitoring sensors are located at the very top of the bridge approximately 130 meters above the water. Information is transmitted via radio modem to BridgeClimb Base station control desk at 10 second intervals.

The weather monitoring system comprises EIT wind speed and direction sensors, and sensors for monitoring temperature and humidity. Each sensor is calibrated to provide a linear 0-1 Voltage output for the measuring range of the sensor.

Information on the PC screen at operation headquarters is updated at 10 second intervals and includes current temperature, humidity, wind speed and direction, average wind speed for the last hour, wind chill factor, Beaufort wind description, daily maximum wind speed plus trends of temperature, humidity and wind speed.

Weather data from the base station receiving radio modem is fed into a PC via the serial communication port and data displayed using the CI Technologies SCADA software ( www.cit.com.au)
