Cup anemometer FA13

IP65with integrated electronicswith mA output

Overview
This FA13 wind speed sensor is engineered for industrial and field applications. It integrates RF and EMI protection, lightning surge protection, a sensitive temperature sensor and automatic PTC heating for frost protection. The wind cups are stainless steel and the aluminum alloy housing features a polyester coating and maze connection design for enhanced sealing. Internal electronics use conformal coating and potting to resist water, salt fog and dust. Multiple output variants (UART, current, RS485) simplify integration.

Features

• Non-contact magnetic measurement technology for durability.
• High accuracy and reliability with low starting threshold.
• Wide measuring range 0–50 m/s and anti-wind capability >70 m/s.
• Stainless steel wind cups (SS304) and high-grade bearings (SS440C) for harsh environments.
• Aluminum alloy housing with polyester coating and IP65 protection.
• Built-in temperature sensor and PTC auto-heating for operation in freezing conditions.
• Available outputs: UART (FA131), 4–20 mA/current (FA133), RS485 (FA134).

Products description and application
The FA13 series is adapted for wind monitoring and data collection across engineering machinery, container cranes, meteorological stations, power plants and traffic systems. Its sealed construction and surge/ESD/EMI protections make it suitable for offshore and industrial sites. Easy to mount with aviation socket wiring and minimal maintenance requirements.
