Load Cell Solutions for Checkweigher Systems
Measure products in motion for weight verification, sorting, filling control and automatic rejection. We support fast-response load cells for food, packaging, logistics and automated production equipment.

A checkweigher must capture a stable signal while the product is moving. Conveyor vibration, belt transitions, product spacing and electrical filtering all affect achievable speed and accuracy.
Typical Checkweigher System
- Fast-response single-point load cell
- Rigid weigh conveyor and isolated frame
- Photoelectric product detection
- High-speed weighing controller
- Reject mechanism and alarm output
- PLC, network and production-data interface
Dynamic Weight Control on Production Lines
Packaged Product Checkweighing
Verify cartons, bags, bottles, cans and trays against target limits with automatic pass or reject decisions.
Filling & Dosing Feedback
Use measured weights to monitor fill consistency, reduce giveaway and support upstream process adjustment.
Sorting & Logistics
Classify products or parcels by weight and combine measurements with barcode and tracking systems.
Information Needed for Sensor Selection
| Parameter | Details to Confirm |
|---|---|
| Product | Shape, dimensions, minimum and maximum weight, stability and packaging |
| Line Speed | Products per minute, belt speed, spacing and available weighing time |
| Accuracy | Target resolution, tolerance limits and allowable measurement variation |
| Conveyor | Weigh-belt length and width, dead weight, drive arrangement and transfer gaps |
| Environment | Washdown, moisture, temperature, dust, corrosion and hygiene requirements |
| Control | Reject signal, analog or digital output, PLC, fieldbus and data logging |
| Installation | Available height, mounting pattern, cable routing and vibration sources |
Four Factors for Reliable Dynamic Results
Minimize flexing and unwanted resonance in the weigh conveyor.
Separate the weighing section from drive and surrounding-machine vibration.
Ensure one complete product occupies the weighing zone at a time.
Verify performance using representative products at normal operating speed.
Checkweigher Load Cell FAQ
Which load cell is used in a checkweigher?
Fast-response single-point load cells are common because they support compact platforms and off-center loading. The final choice depends on capacity, platform size and required speed.
What determines checkweigher accuracy?
Product weight, measuring time, conveyor stability, vibration, transfer design, filtering, environment and calibration all influence accuracy.
How is load-cell capacity selected?
Include maximum product weight, weigh-conveyor dead load, belt tension effects and a suitable allowance for impact and overload.
Can the system control a reject device?
Yes. A weighing controller can compare results with limits and trigger air blast, pusher, drop gate or other reject mechanisms.
Are washdown load cells available?
Stainless-steel and suitably sealed designs can be considered according to cleaning pressure, chemicals, temperature and hygiene requirements.
What is needed for a quotation?
Send product weights and sizes, line speed, accuracy target, conveyor dimensions, environment, output, quantity and installation drawing.
