ARCO-Modbus · Features and Advantages

▪  Compact and extremely robust wind sensor for measuring 

wind direction and wind speed

▪  Friction-free measurement value acquisition through non-

contact measuring principle

▪  Highest reliability by means of precision ball bearings and 

high quality measuring elements

▪  Seawater resistant surface fi nishes for high durability

▪  Low starting value of 0.3 m/s

▪  Very large measuring range from 0.3 to 75 m/s

▪  Quick and easy installation by pipe mounting and M12 plug 

connector

▪  Integrated, regulated heater for optimal heating of the 

sensor heads

▪  Thermal separation between sensor heads and the hous-

ing

▪  Changeable wind vane and three-armed cup anemom-

eter

▪  Sensor head with integrated obstacles prevents infi ltra-

tion of water

▪  Digital output (RS 485 - Modbus RTU)

▪  The compact design of the sensor reduces the eff ort with 

regard to components and their mounting times upon 
comparison with single instruments
