Checkweighers
Dynamic weight control for packed product. Available as a standalone checkweigher, or as a combination system where weighing and metal detection happen at the same point in the line.
StandaloneCombination with detectorHygienic stainlessOne control system
Standalone, or combined with metal detection
Standalone checkweigher
Weight control alone, where metal detection is handled elsewhere in the line or is not required at this point.
- Dynamic weighing of packed product
- Automatic reject of out-of-tolerance packs
- Hygienic stainless construction
- Production statistics and giveaway reporting
Combination: checkweigher + metal detector
Both functions in one frame with one control system. Shorter installation, fewer product transfers, one service visit.
- Less line length than two separate machines
- Fewer transfer points, so fewer jams and less product damage
- One set of product programmes to maintain
- Separate reject streams — underweight and contaminated product must not share a bin
Weighing and detection happen at the same point anyway
On most packing lines the check for weight and the check for contamination sit within a metre of each other — which means two frames, two infeeds, two outfeeds and two transfer points where product can tip or jam.
A combination system removes one of each. There is also a practical service argument: one supplier, one control system, one point of contact when something needs attention, and one visit when it needs calibrating.
| Configurations | Standalone checkweigher, or combination system with metal detector |
|---|---|
| Construction | Hygienic stainless steel |
| Weight range and accuracy | Depends on product and line speed — On request |
| Throughput | Matched to the packing line — On request |
| Reject | Automatic, with separate streams for underweight and metal on combination systems |
| Reporting | Production statistics and giveaway data |
| Detection (combination) | 607 or 608 platform, specified as for a standalone tunnel detector |
Weight ranges and throughput figures are quoted per application. Tell us the pack format and line speed and we will confirm what is achievable.
