Radar Level Sensor Maintenance: How to Avoid 80% of Common Failures Author: Site Editor Publish Time: 2025-05-22 Origin: Site
Daily maintenance checklist:
Antenna cleaning cycle:
Dusty environment: Wipe the horn antenna with alcohol cotton pads every 3 months (metal brushes are prohibited!)
Scale risk: The food industry recommends checking the integrity of the PTFE lining every month
Signal strength monitoring:
Normal range: -30dBm to -10dBm (urgent treatment is required if it is lower than -50dBm)
Common troubleshooting:
Problem: "false echo" is displayed
Reason: Reflection interference from the internal structural parts (ladder/heating tube) of the tank
Solution: Use the echo curve function to shield fixed interference objects
Case: A power plant reduced the radar failure rate from 12 times a year to 2 times by regularly cleaning the antenna.
