Cranes operation in windy conditions could create a potentially dangerous situation. The wind forces imposed on both the crane and the load, which can affect the strength and stability of the cranes. In order to ensure everyone’s safety during lifting operations, it is very important for the members in the lifting team to know the wind speed and resistance.

The challenge to know the wind speed is the connection between sensor and display. Traditional cable solution wouldn’t work well. Scarlet Wireless Anemometer Series provide elegant solutions ranges from the standard display (WR-3), data-logger (WL-11) and full-fledged wireless alarm system (WL-410).

Handheld Receiver
Large LCD display shows digital wind speed, temperature and beaufort chart clearly. Anti-slip rubber on two slides helps users hold the receiver in place during work. User-friendly interface and simple button design allow you to operate the device easily with only one hand.

Users can set wind threshold based on safety standards. When the wind exceeds wind threshold, an audible alarm will be triggered. The alarm will continue as long as high wind is detected. The alarm buzzer on top of the receiver can effectively warn users at the level of 90 dB.
