Bently Nevada 21000-16-10-15-088-03-02 Proximity Probe Housing Assembly

Product Overview

The 21000-16-10-15-088-03-02 is a specialized external mounting assembly designed for the Bently Nevada 3300 XL 8mm proximity probe series. This housing facilitates precise vibration and axial position monitoring in environments where internal probe mounting is restricted by machinery casing thickness or thermal insulation. By incorporating a 1.5-inch standoff adapter and an 8.8-inch penetration sleeve, this assembly ensures optimal probe reach while maintaining an explosion-proof, weather-tight seal (CSA Type 4) to protect sensitive sensor electronics from industrial contaminants and hazardous atmospheres.
