Product Description
The Bently Nevada 21000-16-10-00-077-03-02 is a robust external Proximity Probe Housing Assembly designed to securely mount and protect sensors in critical rotating machinery. It integrates a 3300 XL 11 mm reverse-mount probe for non-contact vibration and shaft displacement monitoring. The housing allows on-the-fly adjustment or replacement of the probe without removing the machine’s bearing cover or disassembling the housing. Engineered for hazardous environments, the assembly features explosion-proof fittings and a rugged dome cover to ensure long-term reliability in industrial applications.

Application Scenarios
This housing assembly is ideal for:
-
Steam and gas turbines, centrifugal compressors, and large motors
-
Applications requiring on-the-fly probe gap adjustment
-
Hazardous industrial locations, ensuring explosion-proof integrity
-
Machines with high shaft movement or thermal growth, where the wider linear range of the 11 mm probe is beneficial
Technical FAQ
Q: Can the sleeve length be extended?
A: Yes. For sleeve lengths exceeding 12 in (304 mm), Bently Nevada recommends using internal probe support (Part No. 37948-01) to prevent vibration-induced fatigue.
Q: What is the advantage of the 11 mm probe versus the standard 8 mm version?
A: The 11 mm probe provides a wider linear range (typically 4.0 mm / 160 mils), offering more margin for machines with large shaft movement or thermal expansion.
Q: Is this housing suitable for hazardous areas?
A: Yes. It includes explosion-proof fittings and is certified for CSA, ATEX, and IECEx compliance.
