A: It should be installed in a straight section of the duct, away from elbows, valves, dampers, and sudden diameter changes, to ensure stable and accurate airflow measurement.

A: Under normal working conditions, clean the probe surface from dust and dirt every 3 to 6 months. In dusty or oily environments, cleaning frequency should be increased.

A: Standard sensors are for normal-temperature, non-corrosive air. For high-temperature, humid, or corrosive gas environments, a high-temperature-resistant or anti-corrosion model must be selected.

A: Common output signals include analog current (4–20 mA), voltage (0–5 V / 0–10 V), and digital outputs such as RS485 (Modbus), to match different monitoring and control systems.

A: Most models are compatible with common duct sizes. For extremely small or large ducts, select a probe with appropriate length or a dedicated installation fixture.

A: Choose a sensor with a slim, streamlined probe to minimize pressure loss and avoid affecting the internal airflow of the ventilation or air conditioning system.
