CQ-818
Chaoqiang
A new-generation digital metal detector with one-button fast auto product setting and 100-product parameter memory — catches ferrous, non-ferrous and stainless contaminants, even through foil packaging, before they reach your customers.
Detection sensitivity is validated per tunnel height. The 818 accepts fully customized tunnel dimensions, rejection types and storage capacity for your specific production line.
| Tunnel Height (mm) | 100 | 120 | 150 | 200 | 250 | 300 | 350 |
|---|---|---|---|---|---|---|---|
| Fe (φmm) | ≥0.8 | ≥1.0 | ≥1.2 | ≥1.5 | ≥2.0 | ≥2.5 | ≥3.0 |
| Non-Fe (φmm) | ≥1.2 | ≥1.5 | ≥1.8 | ≥2.0 | ≥2.5 | ≥3.0 | ≥3.5 |
| 304 SUS (φmm) | ≥1.5 | ≥2.0 | ≥2.0 | ≥2.5 | ≥3.0 | ≥3.5 | ≥4.0 |
Newly Upgraded · Performance Enhancement
Every component is selected to keep your line running — precise detection, fewer false rejects and less operator intervention.
All-digital LCD interface with direction pad and function keys — set products and sensitivity directly on screen, no specialist needed.
Pinpoints the contaminant position precisely, so each reject cycle is clean and consistent with minimal product loss.
Reliable infrared triggering counts and reacts to every contaminated item passing the detection head — accurate every cycle.
Core components are researched and developed with advanced digital technology and original imported chips — the detection coil is filled and sealed in one pass for high accuracy and strong anti-interference.
One-button fast automatic product setting — obtain optimum sensitivity without manual tuning, even when a new product arrives on the line.
304 stainless steel construction resists rust and oxidation in humid, washdown environments — built for daily food-plant use.
Every component of the 818 is engineered to keep sensitivity stable while your line runs at full speed.
The detection coil is filled and sealed in one pass inside the head — high detection accuracy, stable performance and strong resistance to external interference, verified on an empty-machine sensitivity standard.
Food-grade conveyor with pneumatic pusher / flap rejection — contaminated products are pushed off the line into a stainless collection chute. The whole machine is designed to European and American standards for food machinery.
Attention to every mechanical detail keeps the 818 stable in continuous operation and simple for your operators to maintain.
1 Full-digital intelligent metal detector interface with LCD display, direction pad and dedicated function keys for quick setup and product switching.
2 Food-grade conveyor belt with tall side guide rails keeps products centered and running smoothly through the tunnel.
3 Pressure-regulated pneumatic reject system with filter / lubricator units, plus a prominent emergency stop for operator safety.
4 Heavy-duty stainless steel frame on red swivel casters with adjustable leveling feet — move and lock in place in minutes.
The upgraded 818 adds production-grade intelligence: product-effect filtering, foil-pack detection and one-button setup — standard on every unit.
The product effect is learned and filtered automatically, so detection stays stable across different products without manual re-tuning.
Stainless and non-ferrous copper samples can still be detected after products are packaged in aluminum foil.
Customized reverse inspection detects missing metal accessories, desiccants or deoxidizers inside packaged products.
The detection coil is filled and sealed in one pass — high accuracy, stable performance and strong anti-interference.
Store up to 100 product parameter sets — switch products instantly with one-button recall.
Whole-machine design meets food machinery requirements, suitable for in-line inspection operations.
From bakeries to seafood plants — proven on the line across food, aquatic and poultry production.
We are a source manufacturer of inspection equipment — the 818 is built, tested and batch-run in our own plant.
Factory-direct supply — we control machining, assembly and inspection of every 818 in our own plant.
Tunnel width, height, belt speed, reject method and storage are all made to fit your product and production line.
Multiple 818 units running side by side in food plants — stable performance under continuous duty.
100 product parameter groups with one-button recall — meet audit and quality traceability requirements.
Meet the Chaoqiang team at exhibitions worldwide — and bring your samples to test on the machine live.
Tell us your product, belt width and tunnel height — we will configure the 818 to your exact spec.
