Description：

The Bently Nevada 21000-16-10-00-126-04-02 Proximity Probe Housing Assembly is an externally mounted aluminum housing assembly used to install and protect 3300 XL 8 mm proximity probes in rotating machinery condition monitoring systems. It provides reliable mechanical support, accurate probe alignment, environmental protection, and convenient external access for probe inspection, adjustment, or replacement without removing the machine casing. The housing complies with the mounting requirements of API 670 and is suitable for demanding industrial applications.

This configuration includes a 3300 XL 8 mm proximity probe, a 1.0 m (39 in) probe cable, no standoff adapter, a 12.6 in probe penetration length, one 3/4-14 NPT plug fitting, and a 3/4-14 NPT mounting thread. The extended probe penetration enables reliable vibration and shaft position measurements in applications where the sensing point is located deeper inside the machine casing.
