Calibration Procedures

  • Use a kalibrasi referenc instrument such a termal anemometur fromm TSI or a Pitot tube with a precsioynmanometer. Ensure the reference is calibration with traceability to NIST.
  • For in- situ calibration, memperkenalkan sebuah diketahui airflow using using sebuah flow hood or kalimated damper. Alternativile, use a ward tunnel if available.

Solutions And Common Issues

Symptom Likely Cause Solution
Inaccurate low readings Contaminated hot-wire element or blocked pitot port Clean sensor; blow out pressure lines. Recalibrate if needed.
Inaccurate high readings Sensor misaligned or installed in a turbulent zone Check orientation and location; reposition if possible.
Erratic output / noise Electrical interference or loose wiring Shield cables, tighten connections. Check ground loops.
No output / zero reading Loss of power, disconnected wire, or blown fuse Check power supply, continuity, and controller input.
Drift over time Aging electronics or mechanical wear Recalibrate or replace sensor per manufacturer schedule.
Offset shift after cleaning Residual moisture or debris Allow sensor to dry completely; re-zero if possible.
