Working Principle of Check Weigher

The dynamic weighing technology is the working principle of the check weigher. It consists of a high - precision weighing sensor as a core component. When a product passes through the weighing area by conveyor belt, the sensor generates a voltage through gravity to determine the weight of the product. The signals are amplified, filtered, and digitized and sent to an analysis computer system. It compares the measured weight with the set weight range. Once the product's weight is greater or smaller than the preset value, the device will automatically issue an alarm or perform an ejection operation.

Types of Check Weighers  

Checkweigher Conveyor

● Conveyor Checkweigher machine are weighing instruments integrated on conveyors for dynamic weighing.

● High efficiency: Their compact structural design allows for seamless integration with different production lines, effectively saving production space. The conveying speed can be adjusted flexibly according to production needs, suiting weight detection of products with different production paces.

● In addition, they are highly compatible with products of various sizes and shapes, accurately measuring the weight of both square - shaped products and irregularly shaped ones.

Conveyor Belt Check Weigher

● Conveyor belt check weigher use conveyor belts as weighing platforms. They utilize weighing sensors and control systems to monitor product weight.

● Advantages: They keep products stable during the detection process. As shaking is the primary cause of weight - detection errors, this stability ensures more accurate results.

● There is a variety of conveyor - belt materials available, tailored to different product characteristics. For example, the food industry uses food - grade conveyor belts that meet hygiene standards and don't contaminate products.

This type of check weigher can meet the weight - detection requirements of products from different industries.

Weight Weigher Machine

● Weight weigher machine are general - purpose weighing devices. They use high - precision weighing sensors (such as those with advanced strain - gauge technology) to detect product weight. Based on preset values, products are classified or rejected.

● Advantages: They feature high - precision detection performance, capable of accurately detecting even minor weight differences. This meets the needs of industries with strict requirements for product - weight accuracy, like the pharmaceutical industry's weight detection of drug capsules and tablets.

● They have good human - machine interaction functions. Samples are automatically detected, and detection data is automatically recorded and collated to generate detailed weight reports. This greatly helps enterprises with quality traceability, production - process data analysis, and production - process optimization.

Inline Check Weigher

● inline checkweightare highly automated weighing devices commonly used on production lines. They can quickly measure product weight and classify products according to preset values.

●This enables real - time dynamic detection on the production line without halting the process, significantly improving production efficiency. With a rapid response, they can immediately judge product weight and promptly reject substandard products, preventing them from entering the next process.

●They can also be connected to other production equipment. For instance, they can be linked with filling machines to automatically adjust the filling volume based on detection results, achieving automated production - process control.
