Factors Affecting the Detection Distance of Underground Metal Detector


Release time:

2022-06-06

The detection range of the underground metal detector is limited, and the detection distance of the metal detector is generally about 1 to 40cm. The detector is 1-15m, and the remote underground metal detector is related to the brand, model and other factors. The underground metal detector can adjust the high sensitivity and modify the detection disk in the following ways to improve the detection distance, but it will affect the detection distance. Sound detection accuracy.

Sound detection accuracy. There are many factors that affect the distance of the underground metal detector, including the detected metal, soil quality, metal burial time, technical experience, etc.


How many meters can the metal detector detect. When purchasing an underground metal detector, the detection depth is an important parameter. If the detection depth is not enough, it cannot be completely detected. Generally speaking, if you want to detect products buried at a depth of five meters, you need to purchase an underground metal detector. About 8 meters in depth to ensure its detection effect. The bottom of the underground metal detector can detect how deep the ground is, not only with the detector itself, but also with the detection of the environment and the metal detected. Generally speaking, the detection range of underground metal detectors on the market is limited by many factors such as brand, model, size of the detected object, etc. The underground metal detectors are generally about 1 to 40cm, the probe type underground metal detectors are generally about 1-15m, and the remote underground metal detection equipment is 1 to 30 meters deep.

Second, how to improve the detection range of underground metal detectors


The detection distance of the underground metal detector is generally fixed. It is mainly related to hardware. In actual use, there may be various reasons such as object size and other reasons that cannot reach the detection distance. Soil conditions, etc., so what can be done to improve metal detection? What is the detection distance of the detector? In general, the detection distance of the metal detector can only be improved in theory. The specific method is to increase sensitivity, but this method may cause false alarms and increase power consumption. If you want to increase the detection distance, you can modify the detector test plate. If you need a larger detection distance, it is recommended to buy back.


3. What are the factors that affect the detection distance of underground metal detectors?


1. The detection depth of the metal detector is related to the area and shape of the metal to be detected. Shape and weight have a great relationship, generally the larger the area

The larger the number, the larger the corresponding detection depth. On the contrary, the smaller the area, the smaller the number, and the smaller the corresponding depth.


2. The depth of the soil will be different under different conditions, and it will be weaker than if the soil is wet or dense. The signal strength of the detected metal is measured in depth, which reduces the detection rate of the metal detector.


3. Metal burial time The longer the metal is buried, the deeper the detection depth, because the metal will gradually oxidize when buried in the ground for a long time, causing the metal to rust. Diffusion reacts with the surrounding soil, generating a strong magnetic field, and increasing the area of the metal will also increase the strength of the signal.


4. The size and shape of the metal. Under the same environment, the larger the target volume, the higher the signal range, the deeper the detection, and vice versa. Objectives

Shape, the flat coin is usually deeper than the probe depth of the long iron wire, the larger the cross-sectional area, the deeper the probe.
