Bently Nevada 21000-27-05-40-026-03-02 Proximity Probe Housing Assembly – 3300 XL Series
When a proximity probe loses its mechanical housing integrity, the consequences extend far beyond a simple sensor failure. In rotating machinery environments — turbines, compressors, pumps, and generators — an unprotected or misaligned probe means loss of accurate shaft displacement data. Without reliable radial vibration feedback, your condition monitoring system goes blind at the most critical point: the rotating shaft itself. Undetected imbalance, misalignment, or oil whirl can escalate within minutes into catastrophic bearing failure, unplanned shutdown, and six-figure repair costs. The housing assembly is not a peripheral accessory — it is the structural backbone that keeps your probe precisely positioned, mechanically protected, and electrically isolated under continuous industrial stress.
The Bently Nevada 21000-27-05-40-026-03-02 is a precision-engineered proximity probe housing assembly designed for use within the Bently Nevada 3300 XL Series eddy-current transducer system — one of the most widely deployed vibration monitoring platforms in global heavy industry. This specific part number encodes a defined probe length, cable configuration, and mounting geometry, making it a non-interchangeable, application-specific component. Trusted by OEMs and end-users across power generation, oil & gas, petrochemical, and marine propulsion sectors, the 3300 XL Series maintains API 670 compliance and is the de facto standard for turbomachinery protection systems worldwide.
