Possible causes:
- The air or gas might be contaminated with moisture, oil, or particles.
- Turbulent flow caused by nearby elbows, valves, or other obstructions may be affecting readings.
- The sensor could be loose or not inserted to the correct depth.
Solutions:
- Inspect filters and dryers upstream of the sensor to ensure clean, dry air.
- Check for rust, oil, or debris that could be interfering with the sensor element.
- If possible, move the sensor to a more stable section of the pipe, away from bends or valves.
- Make sure the sensor is firmly secured at the correct insertion depth and orientation.
