What is a treasure detector?

The treasure detector is also called underground metal detector and gold detector. This kind of product has many models and different reputation. It is cheaper in China. However, if the treasure detector is actually used, it can predict violent sounds or false alarms in advance. Therefore, it is impossible to judge the existence of underground objects, so it is more troublesome to use this kind of machine.

The treasure detector has the characteristics of wide detection, accurate positioning, strong resolution and simple operation. The probe is mainly used to detect and identify metal objects buried in the ground. While discovering buried gold and silver treasures, historical monuments, antiques, and antiques, it is also a good helper for finding scrap iron.

The treasure detector uses the principle of electromagnetic induction and uses an AC-powered coil to generate a rapidly changing magnetic field. This magnetic field can detect eddy currents in the metal body. The vortex current in turn generates a magnetic field, which in turn affects the original magnetic field, producing the sound of the detector.

The sensitivity control of the treasure detector helps to control the magnetic field of the detector and reduce the influence of electromagnetic interference. If interference occurs, the sensitivity of the magnetic field generated by the detector coil can be reduced, which can reduce the influence of external electromagnetic interference and make the detector work normally. The sensitivity of metal detectors is 1 to 10. It can be adjusted according to the mineralization degree on site.

Metal buried in the ground, through the thick soil layer detection, will be affected by the geological structure. The soil layer contains a variety of minerals, and the detector blocks the metal signal and generates a false alarm signal. People who have used domestic visiters can have this experience. Approaching mounds, stones, and bricks will sound an alarm, which becomes a "Guanghua response". Therefore, the domestic detector can only detect metal objects on the shallow surface, and the metal detector is equipped with a ground balance system, which can eliminate all photochemical reactions and greatly improve the detection depth and effect of the instrument. The detection depth of all portable detectors has a lot to do with the area, shape, weight, burial time, soil quality, soil moisture, and user proficiency of the detected metal. Generally speaking, the larger the area, the more the number, and the soil moisture The smaller, the lower the density, and the longer the burial time, it helps the depth of the instrument to reach a large depth under the circumstances according to the industrial standards of the product. In addition, if the power is low, even if the transmission power is insufficient, the detection depth will be attenuated, and the battery needs to be replaced immediately.

Archaeological treasure detectors are used in archaeology and are also used to find antiquities for archaeologists. Some European countries, such as France and Sweden, need to apply for a license to use the detector, the main purpose is to protect the unexcavated archaeological sites.

Metal detectors have two main functions in the processing industry. One purpose is to prevent metal pollutants from entering the equipment together with raw materials, thereby damaging the equipment and making the equipment unable to use normally. Another purpose is to detect products contaminated by metals, improve product quality, and prevent metal impurities in the products from causing potential personal injury or direct personal injury to users.
