The rigid design protects the sensitive probe tip and extension cable from external impact and high vibration, directly contributing to the high Mean Time Between Failures (MTBF) of the overall vibration measurement channel. When installed in accordance with Bently Nevada installation procedures, the housing assembly supports the intrinsic safety and hazardous area certifications of the complete transducer system, making it suitable for deployment in classified locations.

Technical FAQ
Q: What systems is the 31000-16-05-00-100-03-02 compatible with?
A: The 31000-16-05-00-100-03-02 is an integral component of the Bently Nevada 3300 XL Proximity Transducer System. This system, which includes the probe, extension cable, and a 3300 XL Proximitor Sensor, is designed for direct interface with the Bently Nevada 3500 Machinery Protection System. It is also fully compatible with the legacy 3300 monitoring system. The analog voltage output from the associated Proximitor Sensor can also be integrated with other third-party PLCs, DCS, and data acquisition systems capable of processing a -2 to -18 Vdc signal.
Q: What are the installation requirements?
A: Proper installation is critical for accurate measurement. The machine case requires a mounting hole drilled and tapped for a 3/4-14 NPT thread. An appropriate thread sealant must be applied to the housing's male NPT threads to ensure a pressure-tight seal. The housing is then threaded into the machine case and tightened. The proximity probe is inserted into the housing and its axial position is adjusted to achieve the correct DC gap voltage, typically -10 Vdc for a standard 3300 XL 8 mm probe configuration. Once the gap is set, the probe is secured within the housing using its set screws. Proper system grounding, as detailed in Bently Nevada documentation, is mandatory for signal integrity.
