Anemometer ADVANCED with intergrated alarms for cranes and output pulse Anemometer with alarm beacons and buzzer,commanded by 2 adjustable thresholds. Supplied with fasteners (magnets and flanges). Thanks to its special design, the rotor doesn't generate any perturbation in the surrounding air flow in such a way as to preserve the excellent accuracy of the instrument. The employment of magnetic sensors, allows the access of the wind speed signal inside the anemometer without compromising its waterproof features. • • • • • • • • • • • • • • Automatic selection of supply voltage from 48 to 400Vac (available) 12-24 Vdc model too Compact Waterproof Sturdy Exclusive design Reliable Economic Easily installable Supplied with fixing flanges and magnets Adjustable alarm set points Designed for heavy duty use Verified in wind tunnel Patented Guaranteed for 2 years Technical Features Safety can be improved reducing the speed of the alarm and prealarm set point. Prealarm threshold Yellow lamp and siren are intermittently activated for values of wind speed comprised between 50 and 70 km/h. Alarm threshold When the wind speed exceeds 70 km/h, red lamp and siren are continuously activated until the wind speed drops below the alarm set point (Switch 1 = OFF), or until the equipment will be switched off (Switch 1 = ON). The procedures to reduce alarm and prealarm set points and enable/disable the retentive working of the alarm signals, are described on Figure No.1. Magnets, flanges and supply cable, assure a great simplicity of installation. Reliability and accuracy specifications of every SAG-105WR, are verified in wind tunnel tests. • • • • • Operating temperature -20°C a +60°C IP Protection Degree 65 Dimensions 195x150x270mm Weight 3 kg (cable included) Magnets strenghts >90Kg 1 Nuova CEVA Automation.

Mechanical Features The anemometer is constituted by a rotor in plastic resistant to UV rays, at low temperatures and hail. Rotating on ball bearings, drives a magnetic contact generating 4 pulses per revolution. The aerodynamic shape, has been specifically designed to prevent the formation of ice on the surface of the structure and around the rotor. Electrical Features At the bottom are easily visible the two crowns of high-brightness LEDs that generate a warning flash when the thresholds of wind set, while the central part is housed a BUZZER high-intensity sound working simultaneously...
