Metal Detector Maintenance

The metal detector on a cheese packaging line is usually a HACCP critical control point: a search head that senses ferrous, non-ferrous and stainless contaminants and a reject device that takes the product off the line. It only protects anyone if the settings are the validated ones and the reject works.

Components To Track

ChatterFix builds these as child assets under metal detector, so failure history and PM completions attach to the component that actually failed — not just to the machine.

How Metal Detector Actually Fails

The failure modes worth designing a maintenance schedule around — in rough order of what they cost when they happen.

  • Reject device slow or misfiring so detected product carries on
  • Sensitivity changed from the validated setting
  • Reject bin unlocked or full
  • Product effect from wet or salty cheese causing false rejects
  • Damaged or uncertified test pieces

What To Measure

Recording that a PM was "done" tells you nothing next quarter. These are the readings that let you see a failure coming — and the reason ChatterFix captures measurements against the asset rather than just completions.

  • Test-piece results every shift
  • Reject confirmation on each test
  • Recorded sensitivity settings
  • Reject bin lock and fault stops

Spares Worth Stocking

The parts whose absence turns a short repair into a long outage.

Common Questions

What maintenance does metal detector need?
ChatterFix schedules 5 routines against this asset: die-cast cell entry & molten metal controls (monthly), metal detector function & reject check (monthly), nurse call headend battery test (quarterly), overhead crane & rigging inspection (monthly), relief device tag and record check (monthly). The readings that matter most are test-piece results every shift.
How does metal detector usually fail?
The most common modes are: reject device slow or misfiring so detected product carries on; sensitivity changed from the validated setting; reject bin unlocked or full; product effect from wet or salty cheese causing false rejects; damaged or uncertified test pieces. Most of these degrade gradually rather than failing outright, which is what makes interval-based inspection worthwhile.
What spare parts should we stock?
Certified test piece set, Reject actuator or air blast valve, Belt for the detector conveyor, Photo-eye. The test is lead time, not cost: stock the part whose absence turns a two-hour repair into a two-week outage, even if it is cheap.
Can I track this in ChatterFix?
Yes. Pick your industry at signup and metal detector is created as an asset with its 2 tracked components, with its PM schedule already attached. Technicians then log readings and findings against it by voice rather than typing them in.
