The metal detector adopts assembled differential transformer sensor, and the latest metal detection technology-digital phase shift and related detection technology is adopted in the circuit design. The metal detector has stable and reliable performance, high detection sensitivity, strong material suppression characteristics and strong anti-interference ability.
This product is mainly used in thermal power generation, cement, building materials, paper making, mining, food, chemical industry and other industries. To detect various metal substances mixed in raw materials. It uses the induction signal generated when the metal enters the electromagnetic field of the sensor to drive the actuator to act through the signal amplification processing circuit, thus detecting the harmful metal.
There are three main types of metal detectors:
Electromagnetic induction, X-ray detection and microwave detection are electronic instruments for detecting metals, which can be used in many fields.
Militarily, metal detectors can be used to detect metal mines; In the field of security, it can detect weapons and tools carried or hidden with you; Archaeologically, ancient tombs with buried metal objects can be detected; In engineering, it can be used to detect metal buried objects such as underground pipelines and pipelines; In mineral exploration, it can be used to detect and discover natural gold particles.
The first metal detector in the world was born in 193 1 year. It was invented by Dr. Gerhard R. Fisher in Fisher Laboratory in Palo Alto, California, USA. It was named metallographic microscope and patented.
