Product Description
The 330103-12-20-50-02-00 proximity probe offers exceptional performance in critical condition monitoring applications. It is engineered with Bently Nevada’s industry-leading XL technology, which improves probe durability, cable handling, and temperature tolerance. This 8 mm probe uses eddy current sensing to measure the distance between the probe tip and a conductive surface, usually a rotating shaft.
It features a robust stainless steel casing and sealed construction that prevent contamination from oil, dirt, and moisture. The probe connects to an extension cable and a proximitor sensor, forming a complete non-contact displacement measurement system.
