Combined Metal Detector and Check Weigher
Combined Metal Detector and Check Weigher
The JZYT-Y is an integrated inspection system combining metal detection and checkweighing capabilities, designed to connect effortlessly with diverse packaging lines and conveyor setups. It simultaneously verifies product weight, confirms the presence of all components and leaflets, and screens for metal contaminants. Governed by a PLC controller that stores up to 15 product profiles, the machine employs a push-rod rejection mechanism to avoid damaging products. Electromagnetic wave detection merges analog and digital circuitry, while a 7-inch full-color touchscreen and 100 sensitivity levels enhance usability. Audible and visual alarms trigger blowing or push-rod rejection. Constructed from stainless steel 304 with IP-65 protection, it handles items up to 80 mm in size, covers a weighing range of 10–2000 g with 0.1 g resolution, and achieves sorting accuracy of ±0.2 to ±20 g. Power supply is customizable.
Features:
1. PLC-Based Control Architecture
The system utilizes a programmable logic controller at its core, enabling stable and automated coordination between weighing and metal detection functions within a single integrated unit.
2. Product Memory for Quick Changeover
Operators can store settings for as many as fifteen distinct products, allowing swift transitions between different packaging runs without lengthy recalibration or manual reprogramming.
3. Gentle Push Rod Rejection Mechanism
A push rod style rejection device removes non-conforming items from the production flow, minimizing the risk of physical damage to products compared to alternative ejection methods.
4. Hybrid Detection Circuit Technology
Electromagnetic wave detection combines analog circuitry with digital processing, achieving enhanced signal discrimination for identifying metallic contaminants across a broad range of packaging materials.
5. 7-Inch Full-Color Touch Display
A digital circuit-driven 7-inch touchscreen with full-color LCD presentation serves as the primary operator interface, delivering clear visual feedback and straightforward parameter adjustments.
6. 100-Level Sensitivity Adjustment
Users may fine-tune detection sensitivity across one hundred discrete levels, accommodating diverse product types and varying requirements for contaminant identification on the production line.
7. Dual-Mode Alarm and Rejection
Sound and light alarms operate alongside blowing or push rod rejection options, offering flexible responses when substandard weight or metal contamination is identified during inspection.
8. Check and Print for Non-Conforming Items
Rejected products can be examined and documented through an optional printing function, creating traceable records that support quality control and regulatory compliance efforts.

Applications:
1. Food and beverage packaging inspection – Detecting metal contaminants and verifying product weight in packaged meat, dairy, bakery, and confectionery items for HACCP compliance.
2. Pharmaceutical and healthcare product quality control – Ensuring tablet, capsule, and vial packages are free from metal fragments while confirming correct fill weight and completeness.
3. Chemical and industrial raw material screening – Inspecting bulk bags and cases of powders, granules, and ingredients for metal contamination and weight deviations before shipment.
4. Consumer goods and cosmetics line-end verification – Checking packaged cosmetic and personal care products for missing components and metal particles while validating net weight accuracy.
