Maintenance Tips for Needle Detectors and Metal Detectors

Detection accuracy is directly linked to product quality, and maintaining it requires regular maintenance and calibration. Needle detectors and metal detectors should be verified with standard test pieces on a regular schedule to confirm they can reliably detect metal contaminants of the specified size.

Daily maintenance includes keeping the detection aperture and conveyor clean, checking belt tension and running condition, and regularly cleaning internal dust. The device should avoid impact on the aperture during continuous operation to protect the sensor.

It is recommended to keep maintenance and calibration records with a defined schedule and responsible person. Any inspection anomaly should be resolved before production continues. Standardized maintenance helps extend equipment life and keep detection results stable over the long term.
