电磁感应原理的地下金属探测器

Underground metal detector of electromagnetic induction principle

电磁感应原理的地下金属探测器，俗称“探盘机”！也是市面上，出现最多的地下金属探测器。这类地下金属探测器的工作原理：是探测器的探盘发出一个电磁波信号，当探测到金属目标后，会影响原来的磁场，电磁场信号会发生改变。探测器内部会采集到微弱变化的电磁信号，将信号放大，再经过探测器内部CPU处理。根据不同原理的金属导电性的高低，判断探测到的是什么金属，然后探测器再通过声音和显示探测到的金属目标。

The electromagnetic induction principle of the underground metal detector, commonly known as the "disc machine"! It is also the largest underground metal detector on the market. The working principle of this kind of underground metal detector is that the detector of the detector sends out an electromagnetic wave signal. When detecting the metal target, it will affect the original magnetic field, and the electromagnetic signal will change. In the detector, the weak electromagnetic signal will be collected, the signal is amplified and the CPU is processed inside the detector. According to the conductivity of different metals, we determine what metal is detected, and then detect the metal targets by voice and display.

这个原理的探测器工作稳定，准确率高，深受普通探宝爱好者喜爱。在国外使用的也比较普遍。

The principle of the detector is stable, accurate, popular with ordinary lovers'. It is also widely used abroad.

二、 脉冲原理的地下金属探测器

Two. The pulse principle of the underground metal detector

脉冲地下金属探测器原理为:金属探测器电路中的主要部分是一个处于临界状态的振荡器，当有金属物品接近探测器的线圈时，线圈中产生电磁涡流，使本来就处于振荡临界状态的振荡器停止工作。从而导致报警器响了！

Pulse underground metal detector principle is the main part of the metal detector in the circuit is in a critical state of the oscillator, when there is close to the detector coil metal objects, electromagnetic coil, which was in the critical state of the oscillator oscillation stopped working. So the alarm is ringing!

脉冲感应原理的地下金属探测器，由于工作原理的局限性，这类地下金属探测器只能探测金属，但不能区分金属、屏蔽金属。在当今社会，自然界中充斥着各种垃圾、铁屑等，像这样的机器明显不能满足用户的需求。在国外20年前就已经淘汰这类机器了。但在国内，这类机器仍然充斥着市场，占据着一定市场份额。脉冲原理的地下金属探测器的典型代表是：AR-8、AR-PLAR等。

Because of the limitation of the working principle, the underground metal detectors with pulse induction principle can only detect metals, but they cannot distinguish metals from shielding metals. In today's society, the nature is full of all kinds of garbage, iron chips and so on, such as such machines can not meet the needs of users. This kind of machine has been eliminated 20 years ago. But at home, this kind of machine is still full of market and occupies a certain market share. The typical representative of the underground metal detector of pulse principle are: AR-8, AR-PLAR and so on.
