The metal detector is an instrument used to detect metals and is widely used in industrial production, food detection, safety inspection, and archaeological research. A metal detector is based on the principle that when a changing current is passed through a coil, a changing magnetic field is generated in the space around the coil, which in turn affects the original magnetic field. This in turn affects the original magnetic field. Based on this principle, the Food metal detector consists of a probe and a control unit. The detector consists of a transmitter coil and a receiver coil. The control unit contains the circuitry that supports the operation of the transmitter coil, the signal conversion circuitry that is connected to the receiver coil, and the signal processing and displays unit. Let's take a look at the metal detector.

A brief history of the metal detector.

Depending on their function and application, metal detectors can be divided into the following categories: access metal detectors (security gates for short), handheld metal detectors, portable metal detectors, desktop metal detectors, and industrial metal detectors, and underwater metal detectors. The world's first metal detector was created in 1960. The first metal detectors were mainly used in the industrial and mining industry as a tool to check the purity of minerals and to improve efficiency.

What are the features of the metal detector?

Firstly, the metal detector has an intelligent operating system with a high definition 7" touch screen for intuitive operation. Secondly, the metal detector has a "one-button self-learning" function that can be set automatically after one test, simplifying operation. Thirdly, the metal detector has a user access log and detection log data storage and display, the logs can be traced back to the lake. Fourth, the detection signal strength display can reflect the size of the foreign body signal at any time. Fifth, more than 200 kinds of product testing parameters can be stored, direct call without re-adjustment. Sixth, the detection head can be separated, the belt does not need to be cut. The probe part is made of unique material and production process, high sensitivity, strong anti-interference ability, stable performance, and use cycle of more than 10 years. Seventh, according to production needs, waterproof, dustproof, vibration-proof, and explosion-proof customization. Eighth, the Belt metal detector has an LCD panel, and a Chinese and English operation menu, and users can choose according to needs, with a good man-machine dialogue interface. Ninth, sound and light alarm, at the same time output contact signal to control the motor, can also be reserved to reject the device signal.
