Checkweigher With Metal Detector: A Comprehensive Guide To Make A Better Decision

Blog banner for checkweigher with metal detector for Prompt Scale

Product quality and safety become a crucial factor in meeting stringent regulations. For this, industries like food processing, cosmetics, pharmaceuticals, chemicals, and manufacturing need a precise checkweigher system. The system must comply with industry standards and provide in-depth insights into weighing operations.

What makes this solution more efficient is the combination of metal detection with check-weighing features. Such a solution can detect the slightest deviation in product weight and the presence of metal contaminants in a fraction of a second. Hence, the manufacturing unit gets notified of the underlying issues to resolve them on time.

Check this list of modern features that a modern checkweigher solution must have.

Advanced Features of Checkweigher and Metal Detector System: Taking a Step Ahead

A Checkweigher system with an inbuilt Metal Detector Combo offers a dual-layer checking system for accurate weight measurement and metal detection. It includes the following features that are suitable for industries handling and manufacturing sensitive products.

  1. User-friendly electronic interface

It is all about the usability of a modern Checkweigher system in a manufacturing unit. Hence, the user interface must have the following features.

  • A wide touch-screen with easy-to-understand functions for operating the checkweighing system
  • Automatic weighing compensation to classify products with preset weight measurements
  • Automatic zero tracking (AZT) stops the scale from drifting due to changes in environmental conditions. It helps the machine to maintain its balance of zero within a defined limit.
  • Quick automatic adjustment during the interval of two measuring events enhances measuring rate and operational efficiency. This results in an impressive measurement rate of approximately 100 units per minute.
  1. Flexibility to adjust product weight measurements

A modern checkweigher system with metal detection must have flexible weight measurement features. Such features enable users to measure a diverse range of products in terms of weight. For instance, a checkweigher can measure product bags ranging between 100 and 1200 grams. This means it can be installed in a manufacturing unit where products ranging from 1200 grams can be measured with the highest precision.

Another feature that makes a modern check-weighing solution stand out is its integration compatibility with modern manufacturing systems. Due to its modular, compact design, a modern inline checkweigher must offer smooth integration with any product line.

  1. Weight measurement functions and features

The latest checkweigher and metal detector system must have the following weight measurement functions and features.

  • Weight value storage: Storing weight value provides a computable platform to measure production efficiency. Proper statistical reports can be formulated with the stored weight measurements in the memory of a check-weighing machine.
  • Data export and printability: Another important function of a modern check-weighing system is its data format and export capability. For example, a modern checkweigher can store and export up to 1 million weight measurement data in a readable format. This data can be exported via USB and printed for further calculations.
  • Belt size and speed: Belt speed and size determine how efficiently a check-weighing solution can handle products of different sizes. Modern solutions include a belt size of 40 cm x 25 cm, achieving a maximum speed of 40m/minute. The durability of the belt also determines the smooth flow of this operation. Most modern belts are made of white polyurethane (PU).
  • Weighing accuracy: It all depends on the weighing accuracy of a Checkweigher solution. For example, a checkweigher measuring weights ranging from 100 grams to 1200 grams with an accuracy buffer of ± 0.7 grams is perfect for modern operations.
  1. Metal detection functions

The metal detection function, a crucial part of a checkweigher solution, must be sensitive enough to detect metal contaminants. The fast-moving products on the belt provide very little time to detect microcontaminants. The modern features of metal detection functions are:

  • High-speed metal contaminant detection
  • Alarm or notification feature
  • Auto-programming feature
  1. Design features

These design features of a checkweigher system determine how it can fit in any industrial environment.

  • Industry-grade SS304 stainless steel structure makes it moisture-proof and corrosion-resistant.
  • PU belt for strength, durability, and long-term operational functions
  • Rejection section with push type, air blow, or swing arm feature for careful rejection of substandard products
  • Can handle a maximum humidity level of 90% RH (no condensation)
  • Adjustable metal detector and platform heights
  • Handling weighing operations at a temperature range of 0 to 40°C


Checkweigher with a Metal Detector: A Game-changing Combination

The above mentioned features explain how crucial a checkweigher solution is for industries handling sensitive products. Here is the list of benefits an industry can add to its daily operations.

  • Product quality assurance: Integrating a checkweigher with a metal detection system offers comprehensive product inspection. It enables maintaining the overall quality of products and minimizes the chances of manufacturing substandard products by detecting weight fluctuations and metal contamination.
  • The dual-layer quality assurance plays an important role in manufacturing and packaging pharmaceutical, chemical, agro, dairy, food, and other products.
  • Regulatory compliance: Highly-regulated industrial sectors need precise checkweighing and metal detection machines. Combining these crucial operations under a single roof assists industries in sticking to strict regulatory protocols. Companies can avoid penalties and reputational damage by using such accurate machines.
  • Wastage reduction: A combined metal detector and checkweigher system identify over/underweight or contaminated products before they progress to the next stage. Hence, it prevents wastage and distribution of defective items.
  • Operational efficiency: Proper inspection through a modern checkweigher solution offers operational efficiency with automated detection.


Qualities to Look For in a Checkweigher Manufacturer

We now have a comprehensive idea of what to look into for a Checkweigher system with a built-in Metal Detector Combo solution. The real question is how to identify the right manufacturer to assure quality checkweighers for an industry. Here is what you need to look into.

  • Experience: Look for the experience of a Checkweigher manufacturer. If a brand is a few decades old, it states how it has transformed its solution designs based on technological upgrades and industrial requirements.
  • Certifications and approvals: Checkweigher brands must have proper certifications for manufacturing industry-specific regulatory-compliant machinery. For example, a brand must have its CE certification complying with the European Union’s regulatory standards of earth, environment, and safety.
  • In the same context, the International Organisation of Legal Metrology (OIML) approval is mandatory for the checkweigher machine manufacturers. This international regulatory body determines weight measurement standards for accuracy.
  • Technical support and service: Check how a manufacturer offers assistance in choosing the right technical solution for your manufacturing and packaging unit.
  • Customizable options: Find out the range of solutions a brand offers in this segment. A brand’s diversity in providing checkweigher solutions shows how determined it is to meet specific requirements.

Evaluating these factors will help you choose the right brand and its checkweigher solution.
