Description：

The Bently Nevada 21000-00-00-00-41-04-02 Proximity Probe Housing Assembly is an externally mounted aluminum housing designed to support and protect proximity probes used in rotating machinery condition monitoring systems. The 21000 series provides secure mechanical support, accurate probe alignment, environmental protection, and convenient external access for probe installation, adjustment, or replacement without removing the machine casing. It is fully compliant with API 670 requirements for externally mounted proximity probe housings.

This configuration is supplied without a proximity probe and without a probe cable, allowing users to select compatible probes and accessories based on their application requirements. It features no standoff adapter, a 4.1 in probe penetration, one 3/4-14 NPT plug fitting, and a 3/4-14 NPT mounting thread. The housing is suitable for installations requiring moderate probe penetration while providing a reliable and protected mounting solution for vibration and shaft position monitoring.
