Wireless Anemometer WR-3 – Scarlet Tech

Wireless Sensor

WR-3 applies state-of-art 433/868/900 MHz radio frequency wireless technology to ensure better performance for barrier penetration and achieving long range transmission. The ultra-long 400 meter transmission distance makes WR-3 a perfect gadget to help users monitor wind speed on crane/lift/towers and prevent accidents from high wind risks. Data transmit rate: every 2 seconds.

The sensors automatically send data when wind cups revolve. It goes to sleep mode when wind cups stop for more than 6 hours to save power consumption.

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.

Measurements

• Current, maximum & average wind speed (selectable averaging period)
• Standard units (knots, m/s, km/h, mph)
• Beaufor scale graph
• Temperature in Celsius or Fahrenheit degree
• Wind chill
• Sound alarm at exceeded wind speed

Added Features

• 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.
• Stay Alert
  • Never worries about high wind. Develop a safer working environment. WR-3 Anemometer sends automatic high-volume alarms based on user settings.
• Power Saving
  • 3-years battery life of wind speed sensor in all weather conditions. The sensor is designed to use in rigid environments such as desert, ocean and mountains.
