PRODUCT DESCRIPTION
External proximity probe housing
Bently Nevada 21000-27-05-40-026-03-02 is a proximity probe housing. The housing mounts a proximity probe externally through the machine casing. Its sleeve, conduit connections and screw-in cover provide a mechanical installation for the selected reverse-mount probe; the housing itself is not a separate vibration transmitter or signal conditioner.
3300 XL NSv probe with selectable approvals. The nominal penetration is 2.6 in. Compare the complete probe selection, lead length, standoff adapter, penetration, conduit fittings and mounting thread with the installed assembly. Unresolved ordering fields must be confirmed before installation; a shared base number is not proof of interchangeability.

ACTUAL APPLICATIONS
Applications for 21000 housing assemblies
These applications describe manufacturer-documented family use. They do not establish that this exact ordering code was installed at a named customer site.
-
01 · EXTERNAL MOUNTING
Machine-case probe installations
The housing positions a compatible reverse-mount probe through the machine case. Select the sleeve reach and mounting thread for the actual shaft target, then connect the appropriate complete transducer chain. -
02 · BEARING ACCESS
Long-sleeve bearing installations
The manufacturer describes sleeve supports for installations passing through an inner bearing housing. Additional support limits unsupported-sleeve vibration; the probe lead must remain longer than the selected sleeve. -
03 · SENSING OPTIONS
Family-specific proximity channels
The ordering tables list different probe-family options. Select the housing with the required probe and electrical chain rather than treating every 21000 or 24701 configuration as the same measurement system.

EXTERNAL PROXIMITY PROBE HOUSING
Integrating 21000-27-05-40-026-03-02
The housing mounts a proximity probe externally through the machine casing. Its sleeve, conduit connections and screw-in cover provide a mechanical installation for the selected reverse-mount probe; the housing itself is not a separate vibration transmitter or signal conditioner.
Choose a probe lead longer than the sleeve and support long sleeves near the probe. Combined standoff and penetration beyond 12 inches require support. Short penetration may require counterboring to limit side-view or rear-view effects; follow the actual machine geometry.
Standard 21000 and 24701 housings are not automatically explosion-proof because an explosion-proof fitting is selected. Only the documented CA versions have the stated CSA explosion-proof rating with the required options. Match the selected probe family and complete sensing chain.
Features:
- Match probe selection, sleeve geometry, fittings and mounting interface
- Follow the applicable installation instructions
- Confirm unverified configuration details
The 21000-27-05-40-026-03-02 proximity probe housing requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Replacement of 21000-27-05-40-026-03-02 requires comparing probe selection, sleeve geometry, fittings and mounting interface. A shared base family or similar appearance does not establish a drop-in replacement for the complete ordered assembly.
The manufacturer recommends 31000/32000 housings for installations not requiring explosion-proof housings. This is a conditional housing recommendation, not an exact-order drop-in replacement or a discontinuation notice. Compare all mechanical, environmental and transducer requirements before changing designs.
No verified exact-order discontinuation date, product revision or designated successor is asserted. Document revisions identify the reference literature, not hardware changes to the supplied product. Unconfirmed replacement options must be resolved before substitution.
Features:
- Preserve the complete ordering identity
- Compare the installed electrical and mechanical interfaces
- Do not infer hardware revisions or successor models
The 21000-27-05-40-026-03-02 proximity probe housing requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 21000-27-05-40-026-03-02
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
What does 21000-27-05-40-026-03-02 identify?
It is a 21000 external proximity-probe housing assembly. The housing mounts a proximity probe externally through the machine casing. Its sleeve, conduit connections and screw-in cover provide a mechanical installation for the selected reverse-mount probe; the housing itself is not a separate vibration transmitter or signal conditioner. -
Which probe and mechanical configuration are selected?
3300 XL NSv probe with selectable approvals. The nominal penetration is 2.6 in. Compare the complete probe selection, lead length, standoff adapter, penetration, conduit fittings and mounting thread with the installed assembly. Unresolved ordering fields must be confirmed before installation; a shared base number is not proof of interchangeability. -
How is this housing integrated into a measuring system?
The selected probe must be connected to its matching extension cable, Proximitor Sensor and monitor configuration. The housing provides mechanical access and mounting rather than independent signal conditioning. Match the full probe-family and cable-length requirements before commissioning. -
Which application is documented for this housing family?
The ordering tables list different probe-family options. Select the housing with the required probe and electrical chain rather than treating every 21000 or 24701 configuration as the same measurement system. -
What installation checks are required for the sleeve?
Choose a probe lead longer than the sleeve and support long sleeves near the probe. Combined standoff and penetration beyond 12 inches require support. Short penetration may require counterboring to limit side-view or rear-view effects; follow the actual machine geometry. -
Does a fitting selection establish explosion-proof protection?
Standard 21000 and 24701 housings are not automatically explosion-proof because an explosion-proof fitting is selected. Only the documented CA versions have the stated CSA explosion-proof rating with the required options. Match the selected probe family and complete sensing chain. Verify the housing marking and controlled installation drawing, not just the fitting. -
Can a different housing family replace this complete order?
The manufacturer recommends 31000/32000 housings for installations not requiring explosion-proof housings. This is a conditional housing recommendation, not an exact-order drop-in replacement or a discontinuation notice. Compare all mechanical, environmental and transducer requirements before changing designs.
