Intended Use用途

The Metcorr 117C is a metal detector that is capable of detecting electrically conductive metal objects.

Metcorr 117C是能够检测具有电子传导性金属物体的金属检测器。

The Metcorr 117C is for mines and any other industrial facilities, where deleterious metal objects are to be detected from among conveyed material. The motive for detecting the metal is to prevent damage or excess wear of process equipment, e.g. crushers and grinders. Metcorr 117C用于采矿业和任何其他工业设备,其中检测传送的物料中的有害金属物质。检测金属物质的目的就是避免工艺设备的损坏或者过度磨损,例如:破碎机,研磨机。

The Metcorr 117C metal detector comprises one electronics set, one coil system and one set of interconnection cables. The coil system comprises two identical coil elements which are available in four different sizes - size 08, size 12, size 16, and size 20 (other sizes are available on consultation).

The Metcorr 117C检测器包含一套电子设备,1个线圈系统和1套互接电缆。线圈系统包含2个线圈,该线圈有4种不同尺寸可供选择size08,12,16,20(其他尺寸根据建议使用)

The material, which is to be screened for metal, travels on the conveyor belt between the coils. An electromagnetic field emitted by the transmitter coil excites the conveyed material. Metals, when excited, react in a characteristic manner, which makes them detectable. 将要被金属过滤的物料在传送带上通过线圈之间。发射线圈产生一个电磁场,该电磁场用来激发传送的物料。受激的金属以其特有的方式发生反应,这样使其具有可被检测性。

The Metcorr is provided with an adjustable level of detection. The sensitivity of the system is adjusted at the start-up to a level, which provides for detection of metal objects of harmful size only. Metcorr被装备有一个可调节的电平检测装置。系统的灵敏度在启动时被设置到一个水平,在该水平度仅用于检测金属物质的有害大小尺寸。

The electronics cabinet comprises a pilot relay, by which two control sequences can be implemented and external devices can be activated. 电气柜包含一个辅助继电器,通过该继电器实行控制顺序和激活外部设备。

Operating Theory 操作原理

Transmitter pulses are generated into the transmitter coil by a timed-programmed bipolar current. 通过可编程定时双极电流发送脉冲到发射线圈。

The magnetic field generated by these pulses provides the energy, which excites eddy currents in the target metal objects. Eddy currents excited in the metal by each transmitter pulse will decay after the transmitter pulse is shut off and produce secondary voltages in the receiver coil. These signal voltages, following every pulse, will continue a time, which varies from a few to a few hundred microseconds, depending on the size and electromagnetic properties of the metal object. 由这些脉冲产生的磁场提供能量,这些能量在目标金属物体里产生涡流。由发射脉冲在金属物体里产生的涡流会由于发射脉冲的关闭而产生衰减,从而在接收线圈里产生二次电压。这些电压信号会随着每个脉冲信号持续一段时间,且其值会从几到几百微秒进行变化。其值的大小取决于该金属物质的大小和电磁特性。

The receiver is gated off during the transmitter pulse, and gated on for a short

interval following a short delay while the transmit pulse is off. Therefore, the

receiver functions only during the time interval, when signals occur from any nearby metal objects. A sample is repeatedly taken from the decaying signal. The sampled signals are processed and the time-varying signal component caused by static (i.e. not moving) objects. The amplitude of the signal is finally compared to a detection limit. The sensitivity setting is determined by adjusting the amplification of the signal.


The decay time of the eddy currents generated in ore lumps is much shorter than the decay time in metal objects. This makes the discrimination of metal from ore possible. Only if very magnetic and/or conductive ore appears in large lumps, the discrimination may be somewhat affected.


A detection takes place when the signal level exceeds the detection limit. 当信号水平超过检测极限值时,一次检测生效。

Depending on the implementation, an alarm may be generated to alert the operator. In some implementations, however, there is no need to alert the operator, for example when the metal detector activates a metal separator. 有时一个警报用来警惕操作工,这些情况取决于实际实施情况。但是在某些实际情况,根本就没有必要去警惕操作工,例如 当检测器激发一个金属分离器。

A relay system is built in the detector cabinet to further process the detection signal and to provide practical outputs from the detector. 检测器柜里的继电器系统是用来进一步处理检测信号,并输出提供实际输出信号。

The two-channel method used in the Metcorr 117C reliably helps to detect rod- and bar-shaped metal objects. It has been found out, that any longish metal object creates great varying responses as it is repeatedly conveyed through a simple detector system, but in different orientations. The two windings contained by coil are aligned crosswise. Therefore, if one of the channels gives a weak signal as a result of the unfavorable orientation of the metal object, the other channel creates a much stronger signal. This dual system ensures that the tramp metal objects are detected in a uniform fashion independently of their orientation in relation to the coil. 拥有双通道的方法能使Metcorr 117C较可靠的检测杆和棒状金属物体。 经实践发现,任何一个长的金属物体均能产生很大的变化反应,因为它是一个简单的检测系统通过不同的方向不停的传送信号。线圈中2个绕组横向排列。因此如果其中一个通道给出了由于金属物体的造成不利方向性的微弱信号,那么另一个通道就会产生更加强的信号。这种双重系统确保杂质金属以一致的方式被检测到,而不依赖于与线圈相关联的本身的反向性。
