Bently Nevada 21000-16-10-00-072-03-02 Proximity Probe Housing Assembly
Product Overview
The Bently Nevada 21000-16-10-00-072-03-02 is a precision-machined proximity probe housing assembly belonging to the 3300 XL Series. It is engineered to protect 8 mm and 11 mm proximity probes in harsh, high-vibration environments while maintaining the exact tip-to-target geometry required for accurate shaft-displacement measurements. The assembly incorporates gasketed stainless-steel components, an integral cable retention gland, and an O-ring sealed window cap that allows visual verification of gap spacing without disturbing probe alignment. Its rugged construction, combined with Bently Nevada’s decades of condition-monitoring expertise, makes it the preferred choice for critical rotating machinery in power generation, oil & gas, and heavy-process industries.
