摘要： An oval-shaped sensor is used to measure the material content of the outer ring of a bicolour coin, the coil being mounted on a ferrite whose inner portion has a diameter which is wider than the inner disc of the bicolour coin so that eddy currents are confined to the outer ring. A thickness sensor may be mounted within the oval sensor, and a separate coil is used for measuring the material content of the inner disc. The thickness sensor may also be used for measuring material down to a different depth, for validating clad coins. The oval sensor is used also for diameter measurement.
摘要翻译：具有中心芯[3']和外环[3“]的双金属硬币[2]被放置在自动售货机中的硬币滑槽中，并沿着通过测试区域[12]的斜坡落下，测试区域包括三个电感式传感器[14,16,18]在膜后面的双面线圈布置中，连接到自激振荡器的第一线圈的尺寸和位置使其基本上被硬币的中心芯遮挡，线圈操作在低频处产生关于芯的材料含量的主要信息，第二线圈以更高的频率工作并提供直径信息，线圈尺寸超过中心芯的直径，因此产生专门针对外圈的局部涡流最终线圈[18]相对于外环感测线圈的横向中心偏移，并与第一线圈产生的材料光谱一起产生厚度信息。

摘要翻译：椭圆形传感器用于测量双色硬币外圈的材料含量，该线圈安装在铁氧体上，铁氧体的内部直径比双色硬币的内盘宽，因此涡流是局限于外圈。厚度传感器可以安装在椭圆形传感器内，并且使用单独的线圈来测量内盘的材料含量。厚度传感器也可用于测量材料直至不同的深度，以验证复合硬币。椭圆形传感器也用于直径测量。
