Why WR-3


Cable Free

Get rid of traditional cable-type anemometer. Avoid possible risks from machine operation. Scarlet WR-3 anemometer gives users a wireless wind monitoring solution.


Long Life

4-year battery life of wind speed sensor in all weather conditions. The sensor is designed to use in rigid environments such as dessert, ocean and mountains.


Stay Alert

Never worries about high wind. Develop a safer working environment. WR-3 Anemometer sends automatic high-volume alarms based on user settings.

Wireless Sensor

WR-3 adopts 433/868/900 MHz wireless technology to ensure better performance for barrier penetration and achieving long range transmission. The sensors start sending data when wind cups revolve. The sensor will go to sleep mode when wind cups stop revolving for more than 6 hours. Data transmit rate: every 2 seconds.

The ultra-long 400 meter transmission distance makes WR-3 a perfect gadget to help you monitor wind speed on crane and prevent from high wind risks.

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 allows you to operate the device easily with only one hand.

When the wind reaches a certain speed, an alarm will be triggered, and it will continue as long as high wind is detected. The alarm buzzer located on top of the receiver can effectively warn users at the level of 90 dB.

Long Battery Life

We use innovative low-power consumption wirless technology on WR-3. The battery power consumption is only 20-30 uA in normal condition and 35 mA peak current during data transmission. 3.6V Lithium battery with 2400 mAh capacity can run the sensor for 4 years.

4-year long battery life reduces the maintenance cost significantly. Low battery indicatior on the display monitor will show up when battery capacity is lowered than 10%.

Easy Mounting

An optional aluminum mouting bracket designed for WR-3 wind speed sensors makes the installation on the crane easily. It works along with a bronze bolt plug to keep the sensor perpendicular in any case. Minimize the risk of misleading measurement caused by angles.
