Metal detection monitoring

JL Lennard has introduced AuditCheck to its Goring Kerr DSP range of metal detectors for the food processing and packaging industries, reducing or eliminating quarantine and improving line efficiency.

The system automatically monitors every aspect of metal detection and its operation.

The system measures sensitivity performance and employs a test shuttle that analyses a calibration detection signal that is used as a standard for future tests.

Each time an AuditCheck test is carried out, it is compared to the calibration graph.

Small variations are permitted, but if there are changes due to product build-up or parameter changes, a warning will be given. More serious deviations will generate an alarm.

By monitoring small changes in performance, it is possible to re-calibrate and correct abnormalities before they cause serious line stoppages and loss of production.

The system can be used with various types of metal detection systems including conveyor, pipeline and gravity feed.
