The ZW-FS-N pipeline wind speed transmitter is designed specifically for ventilation, oil fume, and HVAC pipelines, with a built-in high-precision wind speed measurement unit that responds quickly and has low drift. The product adopts RS485 interface and standard ModBus RTU protocol, with a range of 0~30m/s. It supports setting the pipeline cross-sectional area to synchronously calculate the air volume value (m ³/h) in real time. Flanged installation with wind direction arrow markings, intuitive and convenient on-site deployment; The circuit has strong resistance to frequency converter interference and remains stable under harsh working conditions. The device supports DC/AC dual power supply, compatible with software and dip switch dual configuration modes, and comes with screw free terminal blocks, significantly improving installation and maintenance efficiency.
