MAX 500M
Ultra-Long Wireless Transmission▪ Max 500m Ultra-Long Wireless Transceiver▪ Wind Speed, Temp, Air Pressure Sensors▪ Data Recording Up To 1 Year

▪ Impact Resistant & Easy to Install▪ Audible & Visual Wind Speed Alarm▪ Hourly Reports & Historical Graphs

Introduction
Cranes operation in windy conditions could create a potentially dangerous situation. The wind forces exerted on
both the crane and the load can affect the strength and stability of the cranes. In order to ensure safety duringlifting 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 cabled-anemometer wouldn’t work well with the staggering heights among cranes and complex working condition. WR-3 Plus
Wireless Anemometer offers a trusted and stable wind measurement solution.

Features

Application Areas- Max 500m ultra-long wireless transceiver- Audible & visual wind speed alarm- Data recording up to 1 year
- Wind speed, temperature, air pressure measurements- Max 3 years sensor battery life
- IP67 waterproof & impact resistant- Fast & secure magnetic installation kit- Cranes & Construction- Marine, Ports& Offshore- Film Production & Outdoor Entertainment- Scaffolding & Temporary Structure- Rigging & Communications Industry- Wind Farm & Turbine

Functions
Instant Wind Speed Alarm
WR-3 Plus displays the live wind speed value in selectablemeasurement units (m/s, knots, MPH, km/hr) Users can set awind speed warning limit on based on local operation safety
standards. An audible and visual alarm will be trigger when thelimit has been reached. Each sensor has a unique wirelessaddress that can connect to several displays to notify multiple
stakeholders on-site.
Data Recording
WR-3 Plus capture and storage wind speed, temperature, air pressure measurements.
64MB built-in memory and outstanding battery life supports up to 1 year of continuous data recording. (based on
10s logging interval, adjustable: 2s, 5s, 10s, 1min, 5 mins, 10 mins, 60 mins)
The recorded data can be easily export in Excel format further analysis.

Graphical Display
The large LCD backlit display with user-friendly interface clearly indicates live weather data in various units ofmeasurement. Users can view hourly wind records and historical bar charts from the past 12 hours on differentpages.
- Live Wind Speed- Average Wind Speed (selectable averaging)- Maximum Wind Speed- Ambient Temperature- Beaufort Bar Graph- Wind Chill- Atmospheric Pressure
