| 1）通过流水线上的传送带输送产品，在其上面,或者下面安放板式检测线圈，该种方式检测产品中是否已经混入金属异物，这种检测机的缺点是不够灵敏。 1) transport the product through the conveyor belt on the assembly line, and place the plate type detection coil on or below it. In this way, check whether the product has been mixed with metal foreign matters. The disadvantage of this detector is that it is not sensitive enough. 2）另外的安装方式，让产品穿过检测区,食品金属检测机应该将检测线圈安装在金属壳体内部。这种安装方式属于灵敏型线圈构造，壳体内通常固定有3组线圈，其中1个为中间发射线圈,以及2个反绕向的接收线圈,被安装在一个检测头内。高频磁场由与中间线圈相连的振荡器通电后产生,而另外2个反绕向接收线圈彼此各自相连接，确保在周围磁场没有干扰时，可将它们产生的静态感应电压相互抵消。 2) another installation method is to let the product pass through the detection area. The food metal detector should install the detection coil inside the metal shell. This installation method belongs to the sensitive coil structure. Three groups of coils are usually fixed in the shell, one of which is the intermediate transmitting coil, and two receiving coils are installed in a detection head. The high frequency magnetic field is generated after the oscillator connected with the intermediate coil is electrified, while the other two reverse winding receiving coils are respectively connected with each other, so as to ensure that the static induction voltage generated by them can cancel each other when there is no interference from the surrounding magnetic field. |
