Key Features

  1. 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.
  2. 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

  1. Installation:
    • Ensure the mounting diameter and hose mounting position are correctly matched.
    • Install according to instructions, ensuring the drain hole faces downward.
  2. 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.
  3. 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.
