All sensors of the ARCO series are very robust, compact and extremely reliable. Due to its low energy consumption, the ARCO SDI-12 is also particularly suitable for solar-powered weather stations.For a long service life we use corrosion-resistant materials: The housing and the measuring elements are made of seawater-resistant aluminium and stainless steel. The cup rotor, the wind vane and the housing are anodized. The ARCO SDI-12 is a high quality yet cost effective solution.Features– Frictionless data acquisition using non-contact measuring principle- Highest reliability and longevity due to double high-performance bearings and special alloys- Corrosion resistant surfaces for long service life- Particularly low starting value (0.3 m/s)- Measuring range from 0.3…55 m/s- Quick and easy installation thanks to pipe mounting and M12 plug connection- Wind vane and 3-arm cup rotor exchangeable- Increased water tightness due to water traps integrated in the sensor- SDI-12 Protocol, Version 1.4- Low current consumption (< 4 mA at 12 VDC)- The compact design of the sensor reduces the effort required for components and their assembly times compared to individual devices.
