Product Description Amanda Yan Product DescriptionBGT CE 4-20mA RS485 Output Ultrasonic Wind Speed and Direction Sensor Time-of-flight Measurement Across Airflow Monitoring air Flow Sensor Tunnel Ultrasonic anemometerBGT-CF2(H4) crossed type tunnel ultrasonic wind speed and wind direction detector is specifically designed for for the tunnel application, it's working based on ultrasonic time-difference method, the two ultrasonic probes were installed on both sides of the tunnel wall and face to each other, when tunnel airflow passes between the two ultrasonic probes, the time difference between the round-trip times of the ultrasonic waves transmitted by each other is changed by airflow. By measuring the time difference, the airflow velocity is obtained.Features1. Cast aluminum body, anodized surface for harsh environments in the tunnel2. Large sampling area, accurately reflect the air flow rate in tunnel3. Ultrasonic measurement free from influence of ambient temperature4. Non-contact detection, no moving parts, free of maintenanceProduct Parameters Principle Ultrasonic time-difference technologyInstallationWall of tunnel on opposite-sideRangeWind speed -30m/s~30m/sSampling path5m~50mAccuracyWind speed ±0.1m/s Average Time1 sRelay output2 ways dry-contact relay outputDigital interfaceRS232,RS485 Analog output4-20 mA output(load < 500Ω)ProtocolModBusPower supply220VAC±10%,50Hz/60HzProtection GradeIP66Installation Instructions Company ProfilePackaging & Shipping
