Checkweighers for Packaging Lines

LEKA Pack Line (lekapackline.com) supplies LK online checkweighers (XP210, XP500, MN150, D2) for finished-pack weight check and reject, plus LK-D6 for weigh-fill dosing—not a substitute for metal or X-ray inspection. Catalog accuracy and rate bands are empty-machine / catalog references—not rated or guaranteed. Confirm under your product, speed and environment during project review.

Select by weigh range—from under 200 g to ≤40 kg packsOptional reject methods matched to pack type and line layoutSee also LK-D6 combination weigher for weigh-fill dosing
On the packaging line

Where it sits

Usually after filling (and often after capping) to catch under/over-weight packs before labeling or case packing. See also metal detector checkweigher when one footprint must do both tasks, and bottle filling machine for upstream dosing.

Boundary: An online checkweigher verifies finished pack weight after filling. See also LK-D6 combination weigher for weigh-fill dosing into packs—a different role, listed on this page for selection convenience. Neither replaces metal or X-ray inspection.

LK-D6 12–16 head combination weigher

Boundary: LK-D6 doses product into packs (weigh-fill combination weigher). It differs from an inline checkweigher (XP / MN / D2), which verifies finished pack weight after filling.

12-head or 16-head combination weigher. It portions product by target weight, or by weight plus count, before the bagger. It is not an inline checkweigher. Catalog examples are meat, nuts, produce, food, gifts, and bread.

Typical supply AC 220V (confirm single/three-phase for your plant). Plan belt height, left/right reject, and upstream/downstream start-stop links when connecting to a filling or labeling section. Provide line speed and layout sketch for retrofit review—timeline confirmed by project, not from catalog alone.

FAQ

Frequently asked questions

What affects checkweigher accuracy?

Product shape and stability, belt speed, ambient vibration, weighing range, and minimum division all affect results. Catalog accuracy is a reference band; confirm with samples during project review.

Which checkweigher range fits ≤1.5 kg packs vs heavy bags?

LK-XP210 covers ≤1.5 kg packs. LK-XP500 covers up to ≤40 kg boxes and heavy bags. LK-MN150 and LK-D2 suit pieces under 200 g. Confirm size, weight band, and line speed in project review.

Is LK-D6 the same as an online checkweigher?

No. LK-D6 is a 12–16 head combination weigher for weigh-fill dosing into packs. Online checkweighers (LK-XP210 / XP500 / MN150 / D2) verify finished pack weight after filling. They serve different roles; both are listed on this page for selection convenience.

Can I treat catalog figures as on-product performance?

Accuracy bands are catalog reference ranges. Actual results depend on product shape, belt speed, vibration, and environment, and are confirmed during project review.

How do I inquire about an LK checkweigher?
