note: this part typically mounts directly to
the machine via a stud. customers can use
this device with a ---ic 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 ---ic-base onto
the machine greatly reduces the spike signal
so that the unit should not have any issues.

美國bently 3300 xl 11 mm電渦流傳感器系統
美國bently 3300xl 11mm這種電渦流傳感器系統專門用于當我們8 mm傳感器的80 mil (2 mm)線性范圍不能滿足要求時的場合。11 mm電渦流傳感器系統提供**180 mils (4 mm)的線性范圍和100 mv/mil的輸出， 主要用于要求大線性范圍的軸向測向位移、轉速、差脹以及往復式壓縮機活塞桿位置下落測量。有多種螺紋尺寸、探頭配置和安裝附件可供選擇。
美國bently 3300 5 mm / 8 mm電渦流傳感器系統)
美國bently 3300 5/8mm這種電渦流傳感器系統是我們的3300 xl 8 mm系統的---代產品， 我們在所有新的和備件應用中使用3300 xl 8 mm系統。8 mm xl探頭、電纜和前置器和舊的3300系列產品具有互換性。 當8 mm探頭的端部直徑和相應的螺紋尺寸不適用時， 也可以使用5 mm探頭。有多種螺紋尺寸、探頭配置和安裝附件可供選擇。
