Two critical checks · one compact station
Metal Detector Checkweigher Combination Systems
Detect metal contamination and underweight or overweight packs in one coordinated in-line system with production data and verified automatic rejection.
Compact critical control
Why combine metal detection and checkweighing?
A combination system shares product transfer, control architecture and floor space while retaining two distinct inspection decisions. The design can simplify line integration, reporting and operator use—but only when aperture, belt geometry, weighing time and rejection are specified together.

System scope
What a combination inspection station can include
The mechanical and control arrangement is configured for the actual pack, contaminant standard, weight limits, production environment and line speed.
Dynamic checkweighing
- Underweight rejection
- Overweight rejection
- Completeness checks by weight
- Mean and trend monitoring
- Filler feedback options
- Batch production data
Control and rejection
- Shared product recipes
- Fault-specific reject logic
- Reject confirmation
- Lockable reject bins
- Bin-full and air-pressure monitoring
- Fail-safe line-stop logic
Correct specificationAperture, product effect, weighing time and reject distance all matter.
Engineering inputs
What information is needed to specify a combination system?
- 01
Pack dimensions, weight range, material, orientation and centre of gravity.
- 02
Target speed, product spacing, conveyor height, transfers and available length.
- 03
Required metal-detection standard, test pieces and known product effect.
- 04
Weight tolerances, expected variation, filler feedback and reporting needs.
- 05
Cleaning regime, ingress protection, temperature, draught and vibration conditions.
Reject assurance
The failed pack must be removed—and the removal must be proved
Pusher, air blast, drop flap, retracting belt or stop-and-alarm arrangements are chosen around pack behaviour and risk. Reject confirmation, guarded bins and fault monitoring can be included.
Detect
Record the metal-detection or weight failure against the tracked pack.
Track
Maintain product identity from inspection point to reject point.
Reject
Remove the failed pack without disrupting acceptable production.
Verify
Confirm the reject event and trigger the agreed fault response if it fails.

Ask an application question →What is a metal detector checkweigher combination system?
It combines in-line metal contaminant detection and dynamic weight checking on a shared conveyor platform, normally with coordinated controls, product recipes, records and automatic rejection.
Why combine a metal detector and checkweigher?
A combination system can reduce line length, simplify product handling and provide one coordinated inspection and reject point while controlling both contaminant and weight risks.
Can failed packs be separated by fault type?
Yes, subject to layout and risk assessment. Separate reject devices or segregated bins can identify metal-detection and weight failures, with reject confirmation and bin-full monitoring where required.
