A: An automatic checkweigher is a dynamic weighing device used on production lines. It can 100% measure the weight of each product and classify them into two or more groups based on weight.
A: A checkweigher uses load cells to measure product weight in motion. It compares the measured weight to preset limits and automatically rejects out-of-spec products.
A: Checking the net content of products, rejecting overweight and underweight products;
Detecting missing parts in products, such as whether a medicine box is missing its instruction manual;
Checking the fill weight of capsules, rejecting underfilled and overfilled capsules;
Product classification, such as separating chicken legs by weight.
A: Shanghai Shigan Industrial Co., Ltd.’s checkweighers boast first-class manufacturing processes and standards; high accuracy and reliable quality; and a wide range of options to meet almost all your requirements.
A: ◆ Product weight – the heavier the product, the lower the accuracy.
◆ Product throughput speed – the faster the speed, the lower the accuracy.
◆ Product Length – To ensure measurement time, the length of the weighing conveyor belt is determined by the product length; a longer conveyor belt means a faster required speed.
◆ Product Properties and Transmission State – Obviously, liquid and solid products will have different accuracy requirements.
◆ Environmental Factors – Airflow, ground vibration, and extreme temperatures can affect accuracy.
A: The checkweigher is very easy to operate. For example, checkweighers typically have a color touchscreen, a very attractive appearance, and a user-friendly interface, making them easy to operate and allowing for quick changes to product types or the introduction of new products. Clear text information guides you through the operation step by step.
A: Consider:
Product weight range
Speed requirements
Accuracy level
Product type (bag, bottle, capsule, etc.)
Integration with existing line
A: Yes, most modern checkweighers support seamless integration with filling machines, labeling systems, and metal detectors,etc.
A: It mainly detects conductive and magnetically conductive metallic foreign objects, such as gold, silver, copper, iron, aluminum, tin, zinc, and stainless steel.
A: It cannot detect non-metallic foreign objects, such as stones, bones, glass, plastic, and wood blocks.
A: It is applicable to a wide range of industries, including dairy, confectionery, meat processing, beverages, baked goods, seafood, pharmaceuticals, and chemicals.
A: It utilizes the principle that when a metallic foreign object passes through a balanced magnetic field, it cuts the magnetic lines of force, generating an induced electromotive force that disrupts the balance. Advanced technology amplifies and measures this signal to determine whether a metallic foreign object is present.
A: Product effect (moisture, salt)
Conveyor speed
Aperture size
Environmental interference
Metal type
A: Currently, SGWEIGH offers a wide variety of metal detection systems on the market, providing customers with unparalleled adaptability. We offer a wide range of metal detectors, including the SG-M400 for food and chemical products, the SG-M50 for pharmaceuticals (capsules and tablets), the SG-JH-400 for aluminum foil packaging, and pipeline and gravity-fall detection systems for liquids and bulk materials. These systems provide excellent testing capabilities for various products.
Product series include: window type, gravity-fall type, throat type, pipeline type, and tablet/capsule specific type.
Consider:
Product type (wet/dry)
Packaging material
Required sensitivity
Line speed
Yes, combo systems integrate metal detection and weight inspection in one unit, saving space and cost.
