cgesairvel – air velocity 1m probe

Why Choose the Carlo Gavazzi CGESAIRVEL Air Velocity Sensor?

The Carlo Gavazzi CGESAIRVEL is an industrial air velocity sensor with a remote 1 m probe cable designed for accurate airflow measurement in ventilation, HVAC and building automation applications. As part of the Carlo Gavazzi CGES environmental sensor series, it provides continuous air velocity measurement with industry-standard analogue outputs for straightforward integration into monitoring and control systems.

The CGESAIRVEL supports selectable measuring ranges of 0–10 m/s, 0–15 m/s and 0–20 m/s, enabling the sensor to accommodate different airflow requirements. At 20 °C, air velocity accuracy is specified as ±0.2 m/s + 3% of measured value, providing dependable measurements for ventilation and air-handling control.

Operating from a 24 V AC/DC ±20% supply, the CGESAIRVEL provides selectable 0–10 V or 4–20 mA analogue output signals for compatibility with PLCs, controllers and building management systems. The main enclosure measures approximately 80 × 80 × 37.2 mm, while its IP65 / NEMA 4 protection and remote probe arrangement support wall or duct-mounted airflow measurement.
