Widely Use RS485 modbus 4-20 ma Duct Mount Air Velocity Transmitter Sensor

Our transmitter is designed for pipeline wind speed measurement. The self-developed high-precision wind speed measuring unit is responsive and can quickly and accurately measure small wind speeds with good stability, small drift and high precision. The transmitter can also calculate the real-time airflow value based on the cross-sectional area of the pipe measured. The pipeline installation method is convenient for on-site installation. The product adopts anti-interference circuit design, which can withstand various strong electromagnetic interferences such as on-site inverters. The equipment adopts imported screw-free terminal wiring, which is more convenient to use. ■The high-precision wind speed measuring unit has small starting wind speed and sensitive response, and can be applied to occasions with harsh environments such as ventilation ducts and fume pipes; ■Adopting the full-scale secondary calibration method independently developed by the company, the linearity is good and the accuracy is high 1.Open-hole flange mounting with high-quality silicone sealing ring for low air leakage and durability 2.The measuring pipe cross-sectional area can be set, and the real-time air volume value is uploaded according to the set pipe cross-sectional area. 3.Device address support software configuration and dial switch settings 4.The range 0~15m/s, 0~20m/s, 0~30m/s of accuracy is ±(0.2+2%FS)m/s 5.The terminal block adopts the imported screw-free terminal, no tools are needed, and it can be wired as soon as one press and one plug 6.It adopts special EMC anti-interference device to withstand various strong electromagnetic interference such as field inverse. 7.DC 10 ~ 30V wide voltage range power supply, can achieve long-distance centralized power supply 8.With wind speed marking direction for on-site installation.
