PRODUCT DESCRIPTION
Aluminum housing with an eight-inch probe penetration
Bently Nevada 21000-16-05-00-080-04-02 is an aluminum proximity-probe housing configured with a 3300 XL 8 mm probe and a 0.5 m probe cable. Its nominal penetration is 8.0 inches, with no standoff adapter and a threaded machine connection.
The assembly provides external mechanical support and protection for a properly matched proximity measurement channel. Its fittings selection includes one NPT plug only. Verify the machine geometry, probe target, cable routing and connected Proximitor before installation; this ordinary housing designation does not establish CA21000 explosion-proof certification.

ACTUAL APPLICATIONS
Application context for 21000-16-05-00-080-04-02
These uses are supported by the applicable manufacturer documentation. Series-level guidance does not prove that this complete order was installed in a particular customer project.
-
01 · SHAFT VIBRATION
External probe access at fluid-film bearings
The housing supports the configured 8 mm probe at an external machine mounting point. A compatible complete transducer system can measure shaft vibration relative to the bearing; the eight-inch penetration must fit the actual casing and target arrangement. -
02 · POSITION MONITORING
Holding a proximity probe at a static target
An applicable 3300 XL system can measure static displacement from a conductive target. This assembly supplies the mechanical sleeve and housing, while the separately matched probe electronics and target calibration determine the measurement response. -
03 · ROTATION REFERENCE
Maintaining externally mounted Keyphasor pickups
Where target geometry and clearance support a Keyphasor application, the included probe family can provide the rotational reference signal through its matched electronics. Confirm mechanical support and probe gap; the housing itself neither generates nor processes a reference pulse.

Match the probe housing to the machine and sensing chain
This 21000 order combines an aluminum housing and stainless sleeve with the option 16 3300 XL 8 mm probe. The assembly provides mechanical support; it is not a standalone transmitter or signal conditioner.
The ordered 8.0-inch penetration and 3/4-14 NPT mounting thread must match the machine connection and target location. No standoff adapter is supplied, and the probe lead must remain longer than the sleeve.
Select the appropriate probe, extension cable, Proximitor and monitoring channel as a complete system. Check applicable probe instructions and supplied approval markings before connecting or commissioning the installation.
Features:
- Check the eight-inch penetration and machine thread
- Preserve the configured 0.5 m probe cable
- Match the complete proximity measurement channel
The Bently Nevada 21000-16-05-00-080-04-02 proximity probe housing requires the appropriate mounting, connections and configuration to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Use the entire 21000-16-05-00-080-04-02 order when comparing a replacement. A different probe option, standoff or penetration changes the installation even if the housing body looks similar.
The manufacturer recommends 31000/32000 housings for suitable applications not requiring explosion-proof housings. That family recommendation is not proof of direct mechanical or electrical interchangeability with this complete order.
No exact-order discontinuation date, verified product hardware revision or approved replacement order was established in the reviewed official sources. Retain the installed configuration and obtain applicable manufacturer guidance before substitution.
Features:
- Compare every ordered mechanical option
- Do not substitute CA certification
- Verify any newer housing as a system change
The Bently Nevada 21000-16-05-00-080-04-02 proximity probe housing requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 21000-16-05-00-080-04-02
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Does penetration code 080 mean an 80 mm sleeve?
No. The order uses 0.1-inch penetration increments, so 080 specifies an 8.0-inch nominal penetration. This is not a standalone sleeve-length specification; use the assembly drawing and installed geometry. -
Which probe is selected by option 16?
Option 16 specifies a 3300 XL 8 mm probe. Do not describe it as option 28, which separately identifies selectable hazardous-area approvals in the ordering table. -
Does the 0.5 m cable define the complete transducer system length?
No. It identifies the probe cable option supplied with this housing. Select the compatible extension cable and Proximitor using the applicable transducer-system documentation. -
Is a conduit connector included with fittings option 04?
The listed option includes one 3/4-14 NPT plug only. It does not include the additional explosion-proof fitting supplied under option 01. -
When is additional sleeve support required?
The manufacturer requires support near the probe when the combined standoff and penetration exceeds approximately 12 inches. Verify the actual assembled dimensions and use the documented support arrangement to avoid sleeve resonance. -
Can this standard housing be treated as a CA21000 enclosure?
No. The datasheet distinguishes ordinary 21000 housings from CA21000 explosion-proof versions. An enclosure Type 4 rating or a fitting selection does not establish the CA approval for this complete order. -
Can a newer 31000 housing replace it without mechanical checks?
No exact drop-in replacement is established. The manufacturer recommends the newer family for suitable non-explosion-proof installations, but mounting, penetration, environmental requirements and the complete sensing chain still need verification.
