Duct Air Flow Sensor, 0~30m/s, RS485/Analog Output

The duct air flow sensor offers multiple output options including RS485, 4–20mA, 0–5V, and 0–10V to meet the integration requirements of various automation systems. The air flow sensor is suitable for industrial ventilation and gas monitoring, with a measurement range of 0–30 m/s and a resolution as high as 0.1 m/s, enabling precise capture of minute flow velocity changes. It supports various media including air, nitrogen, and fume exhaust gases, making it ideal for ventilation ducts, exhaust systems, and industrial exhaust monitoring.

Feature

• Constructed from ABS material, it operates continuously in 50°C environments with waterproof and dustproof capabilities, ensuring a long service life.
• Address and baud rate are configurable. The duct airflow sensor supports address configuration via software or DIP switch settings.
• The sensor features a PG7 locking connector to prevent water ingress that could affect measurement accuracy. A silicone seal ensures tight sealing between the device and the exhaust duct, minimizing air leakage.
• The dust-proof probe can be inserted into ducts for precise detection and convenient operation. SUCH air flow sensors offer high accuracy and resolution, exhibit zero drift, and maintain excellent long-term stability.

Installation

Installation Notes:

1. First, drill a 20mm diameter hole in the ventilation duct and insert the duct into the hole.
2. Adjust the device orientation so that the arrow direction aligns with the wind direction. Control the device height by adjusting the flange position.
3. Install three screws into the flange to secure the device, completing the installation.

Red Arrow Position: If the prevailing wind is from the north (blowing southward), this arrow should point south.
