Our anemometers are robustly constructed using weather resisting plastics, anodised aluminium and stainless steels enabling them to withstand continuous exposure to the weather including marine environments. They all share the same basic construction and use the same R30 series 3-cup Rotors, different internal modules/components are used to provide different output signals. The use of a precision ball-race mounted shaft ensures the essential low threshold speed and good repeatability. In operation, the wind causes the rotor to rotate at a speed proportional to the wind speed. This rotation is sensed in our optoelectronic anemometers using a slotted disk and an optical beam. In the case of the switching anemometer the rotation is sensed using a balanced system of magnets and a reed-switch. Options common to all the anemometers include anti-icing heaters, marine versions/rotors and mounting adaptors and anti-surge protection.

Available anemometer types include: Low-Power Optoelectronic, Analog/Voltage AND Pulse/Frequency Output - A100L2 Anemometer (ideal for most data-loggers) Low-Power Optoelectronic, Pulse/Frequency Output - A100LM and A100LK Anemometers (also ideal for most data-loggers) Zero-Power, Contact-Closure (Reed Switch) - A100R Anemometer (lowest power of all, suitable for most dataloggers) Optoelectronic, Pulse/Frequency Output - A100M and A100K and A100S Anemometers (suited for connection to PLCs) Analogue/Voltage Output - Porton A100 and A100H Anemometers
