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。
