Note: This part typically mounts directly to
the machine via a stud. Customers can use
this device with a magnetic base, but must
take care not to “snap” the unit onto the
machine. This snapping action can create a
very large spike signal that can damage the
electronics. Rolling the magnetic-base onto
the machine greatly reduces the spike signal
so that the unit should not have any issues.

美国BENTLY 3300 XL 11 mm电涡流传感器系统
美国BENTLY 3300XL 11mm这种电涡流传感器系统专门用于当我们8 mm传感器的80 mil (2 mm)线性范围不能满足要求时的场合。11 mm电涡流传感器系统提供**180 mils (4 mm)的线性范围和100 mV/mil的输出, 主要用于要求大线性范围的轴向(测向)位移、转速、差胀以及往复式压缩机活塞杆位置(下落)测量。有多种螺纹尺寸、探头配置和安装附件可供选择。
美国BENTLY 3300 5 mm / 8 mm电涡流传感器系统)
美国BENTLY 3300 5/8mm这种电涡流传感器系统是我们的3300 XL 8 mm系统的前一代产品, 我们推荐在所有新的和备件应用中使用3300 XL 8 mm系统。8 mm XL探头、电缆和前置器和旧的3300系列产品具有互换性。 当8 mm探头的端部直径和相应的螺纹尺寸不适用时, 也可以使用5 mm探头。有多种螺纹尺寸、探头配置和安装附件可供选择。
