Overview of Metal Detectors
Brief history of metal detectors
Metal detectors have a fascinating history that dates back to the late 19th century. The first known patent for a metal detector was filed in 1881 by Alexander Graham Bell, the inventor of the telephone. However, it wasn’t until the early 20th century that metal detectors started being used for practical applications.
During World War II, they played a crucial role in locating landmines and unexploded ordnance, saving countless lives. Since then, their use has expanded to various fields, including archaeology, treasure hunting, gold prospecting, and security screening.
Types of metal detectors (e.g., VLF, PI, BFO)
There are several types of metal detectors available on the market today. The most common ones include Very Low Frequency (VLF), Pulse Induction (PI), and Beat Frequency Oscillation (BFO) detectors.
1. VLF Metal Detectors: VLF detectors function by transmitting a low-frequency electromagnetic field into the ground.
When this field encounters metallic objects, it induces an electric current within them which is then picked up by the detector’s receiver coil. These types of detectors are known for their ability to discriminate between different types of metals and provide target identification features.
2. PI Metal Detectors: Pulse Induction detectors use bursts of electrical current to generate magnetic fields in short pulses. When these pulses encounter metal objects underground, they create eddy currents within them that produce a secondary magnetic field visible to the detector’s coil.
PI detectors excel at detecting deeply buried or highly conductive targets like large caches or mineralized soil with high iron content.
3. BFO Metal Detectors: Beat Frequency Oscillation detectors operate by generating two oscillating frequencies—a reference frequency and an adjustable frequency affected by any nearby metallic objects.
When the adjusted frequency matches the reference frequency, an audible signal is generated. BFO detectors are generally easy to use and more affordable, but they are less accurate in discriminating between different types of metals.
How metal detectors work
Regardless of the type, metal detectors function based on the same basic principles. They consist of a control box, a shaft with a search coil or coil set, and a display unit or audio output.
When turned on, the control box sends an electrical current through the coil or coils within the search head. This current generates a magnetic field around them.
When this field encounters a metallic object in its vicinity, it induces electric currents within that object. These induced currents create their own magnetic fields that oppose the original magnetic field generated by the detector’s coil(s).
The resulting disturbance is detected by sensors in the control box and converted into an audible signal or displayed on-screen as a visual indicator. Metal detectors can be fine-tuned to detect specific types of metals by adjusting settings such as sensitivity and discrimination levels.
Sensitivity determines how deep into the ground signals can be detected, while discrimination allows users to eliminate signals from unwanted metals based on their conductivity or specific response patterns. Overall, metal detectors operate through intricate electromagnetic processes that enable users to locate buried metallic objects with pinpoint accuracy across various applications and industries.
