Industrial Tunnel Metal Detector Head

                                                                                                                             Industrial Tunnel Metal Detector Head 

This industrial tunnel metal detector head is a standalone detection unit, designed to be retrofitted onto your existing production conveyor system. It identifies ferrous, non‑ferrous and stainless‑steel contaminants inside packaged or bulk products on‑line. Widely deployed in food, pharmaceutical, plastic and daily‑chemical industries for HACCP & food safety compliance.

This listing supplies only the metal detector main head, conveyor frame, belt and drive motor are NOT included. It is ideal for factories wanting to upgrade existing assembly lines without replacing full conveyor sets.

The metal detector uses an electromagnetic field to inspect the inspected products on the conveyor line. When a metal signal above the set value is detected, it outputs an alarm for metal mixing or outputs a rejection command signal issued by a selector.

 Features：

• Using the latest generation of digital signal processing (DSP) technology and intelligent algorithms to improve the detection accuracy and stability; is also the only digital metal detector using DSP technology.

• can effectively inhibit the product effect; able to detect products with larger products, such as: frozen food, meat, rice, pickles, fish paste

• With smart settings, the device automatically sets the optimum sensitivity for the product being tested, making it easy to operate.
  

• Memory function: Save the best sensitivity, the next test can be directly detected, can store more than 50 kinds of product testing parameters;
  

• LCD screen display, menu in English and Chinese, easy to achieve man-machine dialogue operation；
  

• Can detect iron, stainless steel, copper, aluminum and lead and other metal materials
  

• Flexible digital sensitivity control and a variety of advanced manual settings; a variety of specifications to choose from, to meet the sensitivity of different materials testing requirements;

• All stainless steel SUS304 manufacturing, high-grade protective motor to choose from;

• Simple detachable rack, easy to cleaning; conveyor belt special design, to avoid conveyor belt deviation，

• A variety of exclusion method  can be selection. Accurate reject control to ensure that foreign matter is a reliable removal of the least material waste;

Auto Reject:

• Equip a suitable reject  according to product size and weight (Option).

• Belt stop and audible alarm is a basic option.

• Continuously monitoring. Conveyor runs without stop while detecting contaminated products

Application Industries：

Food industry: Meat, seafood, frozen food, snacks, baked goods, sauce, grain

Pharmaceutical & health‑care products

Plastic & rubber raw material pellets

Cosmetics & daily chemical products

Other manufacturing requiring foreign metal contamination inspection

FAQ：

Q: Does this unit come with conveyor belt and motor?

A: No. This product is only the metal detector detecting head. Conveyor system needs to be provided by buyer.

Q: Can it work for wet and salty food?

A: Yes. Built‑in anti‑product‑effect algorithm reduces false alarms caused by conductive wet food.

Q: What accessories can I connect?

A: Audible‑visual alarm light, pneumatic reject device, stop‑line signal, photoelectric sensors.

Q: Can you customize tunnel size?

A: Yes, we offer OEM for different tunnel width and height according to your product size
