Renke Industrial 4-20mA 3 Cup Anemometer Wind Speed Meter Sensor RS485 Modbus Price with CE

Three parabolic cup design captures wind from any horizontal direction with 0.1 m/s resolution across a 0 to 60 m/s measurement range on RS485 and pulse output models.

Accuracy scales with wind speed using a combined fixed and velocity-proportional formula, delivering tighter error control at low speeds and proportionally accurate readings at higher velocities.

Cable exits from the base rather than through an aviation plug gasket, removing a common long-term weathering failure point and improving rain and snow resistance over years of field use.

Four-core shielded cable construction resists water ingress, oil exposure, and electromagnetic interference, ensuring reliable signal transmission in industrial, marine, and harsh outdoor environments

Full aluminum alloy construction with sprayed surface coating delivers high strength, corrosion resistance, and rust-free performance through years of continuous outdoor deployment.

RS485, 4 to 20mA, 0 to 5V, 0 to 10V, and pulse outputs available. Pulse variant achieves 0.5s dynamic response versus 2s on analog and RS485 models for time-critical applications.

Bearings and weight distribution are carefully engineered to minimize moment of inertia, enabling faster mechanical response to wind speed changes than heavier conventional cup designs.

RS485 model draws only 0.3W at 12VDC, enabling long-term solar or battery-powered deployment in remote greenhouses, weather stations, docks, and aquaculture monitoring sites.

Operates across extreme cold and hot outdoor environments up to 95% non-condensing relative humidity, covering most global climate conditions without additional environmental protection.

Rated for 5 to 8 years of service life under normal conditions, backed by a 2-year overall warranty, reducing total cost of ownership in long-term meteorological and industrial deployments.
