Dynamic Checkweigher: High-Speed Automated Weighing Systems | SameGram
In the modern manufacturing landscape, precision isn’t just a goal—it’s a regulatory requirement and a brand promise. Checkweighers help you check the accuracy of package weight and contents, serving as the final gatekeeper of quality on your production line. Whether you are in food processing, pharmaceuticals, or logistics, a Dynamic Checkweigher is the cornerstone of an automated, compliant, and efficient facility.
At SameGram, we specialize in high-speed, high-precision automated weighing solutions designed to eliminate human error and ensure every product leaving your factory meets the strictest standards.
1. Authoritative Definition: What is a Dynamic Checkweigher?
A Dynamic Checkweigher is an advanced, automated system used within a production line to measure the weight of individual items as they move across a conveyor belt. Unlike traditional static scales that require the production flow to stop, a dynamic system performs real-time weighing "on the fly."
The primary function of a SameGram Dynamic Checkweigher is to verify that the weight of a finished product falls within a specific, pre-defined tolerance. It identifies:
● Underweight products: Which can lead to consumer complaints and legal issues.
● Overweight products: Which result in "product giveaway" and reduced profitability.
● Incomplete contents: Detecting missing components, such as a manual, a lid, or a secondary item within a package.
In a regulatory context, these systems are also utilized as a critical control point to ensure products do not contain unauthorized foreign objects that would shift the weight profile, ensuring total compliance with safety standards.
2. How It Works: The Science of High-Speed Precision
The SameGram weighing system is engineered for seamless integration. The process is divided into three critical zones:
1. Infeed Zone: Products are spaced correctly to ensure only one item is on the weighing platform at a time.
2. Weighing Zone: This is the heart of the machine. As the product passes over the highly sensitive load cell, the system captures the weight instantly. SameGram’s proprietary algorithms filter out mechanical vibrations to ensure a pure weight reading.
3. Reject Zone: If a product is identified as out-of-tolerance, the system triggers an automatic rejection mechanism (such as an air blast, pusher, or diverter) to remove the item from the line without stopping the flow.

3. Technical Parameters and Range
SameGram systems are built to handle a diverse range of industrial needs. Our technical specifications are designed to offer flexibility for various packaging formats, from small sachets to heavy cartons.
| Feature | Specification Range | |
Weight Range | 5g to 50,000g (Customizable models available) | |
Highest Accuracy | Up to ±0.1g depending on product speed and weight | |
Max Speed | Up to 300 pieces per minute (PPM) | |
| Belt Width | 100mm to 600mm | |
| Construction | SUS304 Stainless Steel (IP65/IP66 Washdown rated) | |
| Display | 10-inch Full-Color Touchscreen HMI | |
Our systems utilize advanced digital signal processing (DSP) to maintain stability even in high-speed environments, ensuring that your Dynamic Checkweigher remains a reliable asset for years.
4. Application Scenarios: Where Accuracy Meets Automation
The versatility of the SameGram Dynamic Checkweigher allows it to thrive in numerous sectors:
● Food & Beverage: Ensuring "Net Weight" compliance for snacks, frozen foods, and beverages. It is essential for detecting missing seasoning packets or ensuring a tray of meat has the exact weight labeled.
● Pharmaceuticals: In an industry where a missing blister pack or a single bottle can have medical consequences, our systems provide 100% inspection of cartons and bottles.
● Chemicals & Cosmetics: Checking the fill-level of expensive creams or hazardous chemicals to prevent leakage or under-filling.
● Logistics & E-commerce: Verifying that a box contains all the items ordered by a customer before it is shipped.
Integrating a SameGram system into your automated line reduces the need for manual sampling, significantly lowering labor costs and virtually eliminating the risk of a product recall.
5. Industry Standards and Regulatory Compliance
Adhering to international standards is not optional; it is a necessity. SameGram equipment is designed to help your facility comply with:
● HACCP/GMP: Critical for food and drug safety.
● OIML R51: The international standard for automatic weighing instruments.
● FDA Requirements: Ensuring packaging integrity and preventing contaminated or incorrect products from reaching the market.
By using a Dynamic Checkweigher, your company creates a transparent data trail. Our systems can export detailed production reports, providing "Proof of Compliance" during audits.
6. Common Misconceptions vs. Reality
Misconception: "Static scales are just as good as dynamic ones."
Reality: Static scales require manual intervention, which creates a bottleneck. A Dynamic Checkweigher from SameGram keeps your line running at full speed, inspecting every single unit rather than just a small percentage.
Misconception: "Checkweighers are only for weight; they can’t detect quality issues."
Reality: In many cases, weight is quality. If a product is supposed to contain 10 tablets but weighs 9, the checkweigher detects the quality failure immediately. It is an automated "X-ray" for weight-based content verification.
7. Frequently Asked Questions (FAQ)
Q: How does a dynamic checkweigher improve my ROI?
A: By reducing "product giveaway" (over-filling) and preventing expensive fines or recalls associated with under-filling. Most SameGram clients see a return on investment within 6 to 12 months.
Q: Can it be integrated into my existing production line?
A: Absolutely. SameGram systems are designed with modularity in mind. They can communicate with your existing PLC and upstream/downstream equipment via standard industrial protocols.
Q: What happens if the environment is wet or dusty?
A: We offer IP65 and IP66 rated stainless steel models specifically for "washdown" environments, common in the meat and dairy industries.
Q: How often does the machine need calibration?
A: While our systems are highly stable, we recommend a daily "zero-check" which the machine performs automatically, and a formal calibration check according to your internal QA schedule.
