CQ-808
Chaoqiang
A digital metal detector built on dual signal detection circuit merging technology — ultra-high sensitivity, strong anti-interference and anti-shock performance. The moment metal is detected, the conveyor stops automatically and a 12V buzzer alarm sounds, protecting your line and your customers.
Detection sensitivity is validated per tunnel height. The 808 accepts fully customized tunnel width (200-2000mm), height and alarm logic for your specific production line.
| Tunnel Height (mm) | 100 | 120 | 150 | 200 | 250 | 300 | 350 |
|---|---|---|---|---|---|---|---|
| Fe (φmm) | ≥1.0 | ≥1.2 | ≥1.5 | ≥2.0 | ≥2.5 | ≥3.0 | ≥3.5 |
| Non-Fe (φmm) | ≥1.5 | ≥2.0 | ≥2.5 | ≥3.0 | ≥3.5 | ≥4.0 | ≥4.5 |
| 304 SUS (φmm) | ≥2.0 | ≥2.5 | ≥3.0 | ≥3.5 | ≥4.0 | ≥4.5 | ≥5.0 |
Newly Upgraded · Performance Enhancement
Dual-signal digital core, precise positioning and a hygienic all-stainless build — engineered to keep your line protected with less operator intervention.
Digital display with dual sensitivity indicators and dedicated function keys — set products and sensitivity directly on screen, no specialist needed.
Dual signal display pinpoints the contaminant and its relative size precisely, so operators react fast and product loss stays minimal.
Reliable infrared triggering detects every contaminated item passing the detection head — accurate response every cycle.
Core components built on advanced digital technology with intelligent imported chips — the detection coil is filled and sealed in one pass for high accuracy and strong anti-interference.
Product-effect filtering stabilizes detection across different products — less false alarms and no manual re-tuning when products change.
Full SUS304 cold-drawn stainless steel resists rust and oxidation in humid, washdown environments — built for daily food-plant use.
Every component of the 808 is engineered to keep sensitivity stable while your line runs at full speed.
A one-pass filled and sealed coil inside the head combines with the dual-signal merging circuit — delivering stable, high-accuracy detection with strong anti-interference and anti-shock performance on every shift.
An intelligent imported chip drives the detector — self-learning and memory functions optimize detection head accuracy and sensitivity automatically, keeping performance consistent on every shift.
Attention to every mechanical detail keeps the 808 stable in continuous operation and simple for your operators to maintain.
1 Simplified display with dual sensitivity indicators (Sensitivity 1 & 2), WORK / DEBUG / START / STOP controls and a red detect alarm — extremely easy to operate.
2 A hygienic food-grade belt with tall side guide rails holds products centered and steady through the tunnel — easy to clean and ready for continuous washdown duty.
3 Advanced 304 stainless steel with cold-drawing process — no rust and strong oxidation resistance in humid washdown environments.
4 The 808 rides on a heavy-duty stainless steel frame with red swivel casters and adjustable leveling feet — reposition and level the machine in minutes on any plant floor.
The upgraded 808 adds production-grade intelligence: dual-signal merging, auto-stop alarm and self-learning — standard on every unit.
Merging dual detection circuits delivers ultra-high sensitivity with strong anti-interference and ultra-strong shockproof ability.
When metal passes through, two signal indicators display different sensing intensities based on the size of the metal — precise, visual feedback.
The machine stops automatically on detection and outputs a 12V buzzer alarm — immediate, unmistakable protection for your line.
Intelligent imported chip with memory and self-learning optimizes detection head accuracy and sensitivity automatically.
The product effect is learned and filtered automatically, so detection stays stable across different products without manual re-tuning.
Dual-signal digital design meets European and American food machinery requirements — ready for in-line inspection in food, pharmaceutical and textile plants.
Built for detecting metal impurities in products or raw materials across food, pharmaceutical, textile and more — iron, copper, aluminum and stainless steel all covered.
We are a source manufacturer of inspection equipment — the 808 is built, tested and batch-run in our own plant.
Factory-direct supply — we control machining, assembly and inspection of every 808 in our own plant.
Tunnel width from 200-2000mm, height 100-350mm and alarm logic are all made to fit your product and production line.
Multiple 808 units running side by side in production plants — stable performance under continuous duty.
Smart chip memory stores product parameters for consistent, repeatable inspection — 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 808 to your exact spec.
