Description
The Airmobi Rainproof & De-icing Pitot Tube / Airspeed Tube is specifically designed for UAV airspeed data collection, particularly under adverse weather conditions such as rain, snow, and high-altitude environments. This product prevents rain and frost from blocking the airspeed tube, ensuring that UAVs can collect dynamic airspeed data reliably.
Specifications
- Type: Rainproof & De-icing
- Dimensions: Φ12*134mm
- Mounting Diameter: Φ12mm
- Hose Mounting Position: Φ4mm
- Weight: 20g
- Supply Voltage: 18V-26V DC
- Maximum Power Consumption: 15W
- Operating Temperature: -40℃ to 80℃
- Cable Length: 380mm
- Sensor Type: NTC Thermistor 50K3950
Key Features
- Heating Function:
- Heating power can be supplied directly by DC power or controlled via temperature sensor feedback for constant temperature. At 24V power supply, the current is 0.5A.
- Protective Design:
- Avoid touching the airspeed tube when heating to prevent burns.
- Long-term direct DC power supply is not recommended in high-temperature ground environments without airflow. Constant temperature control is not restricted by this.
- Do not turn on the heating function when the dust cap is covered.
- Ensure the drain hole is installed facing downward to prevent water accumulation.
Operational Notes
- Installation:
- Ensure the mounting diameter and hose mounting position are correctly matched.
- Install according to instructions, ensuring the drain hole faces downward.
- Usage:
- Choose either direct DC power or constant temperature control as needed.
- Avoid using direct DC power supply for extended periods in high-temperature environments without airflow.
- Maintenance:
- Regularly check the airspeed tube and heating system to ensure there are no blockages and that the system functions properly.
- Do not use the heating function when the dust cap is covered to avoid malfunction.
