Aerovane Transmitter Series 140A

Features

Large size and aerodynamic design assures low starting torque, directional stability, minimal impact from ice and snow, and large air sample size. Magnetic sensor and totally encapsulated electronics assure operation in presence of moisture and particles and are designed to comply with intrinsically safe requirements under ATEX guidelines. Made of high impact thermoplastic and mounted to a machined aluminum base the AEDA 200 will provide wind information up to 200 mph wind speeds.

Wind speed is sampled over a 182.6 in.² (1178 cm²) area by proven 3 blade impeller which is mounted to a stainless steel shaft and connected through sealed bearings to a high reliability magnetic sensor that provides digital pulse output directly related to rotational speed of the impeller. The large sample area minimizes wind speed errors due to micro turbulence particulates in the air while assuring low starting thresholds and accuracy of low wind speed measurements. Starting threshold of less than 2 knots and accuracy of wind measurements of 1 knot with 0.2 knot resolution are obtained in the worst environmental conditions.

Wind direction is provided by a large aerodynamic rudder attached to the vane and connected proprietary magnetic sensor through a sealed bearing to measure wind direction (with no dead zone) to and accuracy of 1° (0.2°), the best in the industry. The large rudder section (130 in², 839 cm²) of the Aerovane assures wind direction accuracy and stability (minimal modulation caused by turbulent flow over tail section) using the proven laminar flow tail design of the predecessor Belfort Series 120 Aerovane. Balanced about its center of rotation with its long cord length (distance from mounting shaft to tail) and large airfoil tail design the AEDA 140A provides excellent sensitivity to small wind direction changes at low airflow while sampling a large cross section of air to minimize impact of micro turbulence.

The AEDA 200 is available with optional thermostatically controlled heaters to prevent freezing during icing conditions to temperatures of 14°F (-10°c) and operation of electronics to -55°c.
