• Compact, easy to mount and low maintenance; aviation socket wiring.

Product description and application
The FA21 wind combined sensor series is designed for industrial and outdoor meteorological applications. The series includes model variants FA213 (current signal) and FA214 (RS485 signal). The unit integrates surge and electrostatic protection, a sensitive temperature sensor and automatic heating to prevent freezing. The wind cups and housing use corrosion-resistant materials and a maze-structure connection to reduce ingress of water and dust. Internal electronics feature conformal coating and potting for enhanced environmental protection. Typical applications include wind monitoring and data collection for engineering machinery, container cranes, meteorological stations, power plants, traffic monitoring and other industrial fields. CMC manufacturing license for measuring instruments is approved.
