What is 21000-34-10-00-054-04-02?

The Bently Nevada 21000-34-10-00-054-04-02 is an aluminum Proximity Probe Housing Assembly. It allows operators to externally mount and access proximity probes—permitting gap adjustments or probe replacements without having to disassemble the machinery.

What is the primary purpose of this housing assembly?

It is designed for the external mounting of proximity probes on rotating machinery. It provides a secure enclosure for the probe and its extension cable, protecting them from harsh environments while granting easy physical and electrical access.

Can I replace a probe or adjust the gap without stopping the machine?

No. While the housing allows external access for these tasks, the machine must be safely shut down and locked out (if required by your facility's safety protocols) before you open the housing, adjust the gap, or replace a probe.

What does the (-34) probe option signify?

This indicates the inclusion of a Bently Nevada 3300 XL NSv (Near-surface) Proximity Probe. This specific probe is often used in applications with limited side-view clearances, shorter linear ranges, or smaller diameter targets

Are there length restrictions for the probe sleeves?

Yes. If your penetration or standoff options result in a total sleeve length greater than 304 mm (12 inches), Bently Nevada requires an additional sleeve support (e.g., an oil seal/probe support) near the probe tip to prevent vibration and resonance from causing damage.

Sleeve length is determined by the location inwhich the probe and housing are installed. Theprobe lead must be longer than the sleeve.Sleeve lengths longer than 304 mm (12 inches)require additional sleeve support to reduce thevibration associated with unsupported longsleeve lengths.Bently Nevada offers a probe support and oilseal (part number 37948-01) for long sleevesthat must go through an inner bearing housing.

Petrochemical & Refining:Monitors pumps/compressors/turbines in explosion-proof zones
Power Generation Plants:Coal/gas/hydro: monitors large steam & gas turbines
Discrete Manufacturing:High-vibration lines: continuous shaft position monitoring
Oil & Gas Facilities:API 670 & explosion-proof for offshore/LNG
Pulp, Paper, & Steel Mills:Protects sensors from dust/moisture/mechanical stress
Specialized Processing:Fertilizer/sugar/food: machine health critical to output
