Bently Nevada 21000-34-10-20-058-04-02 Probe Housing Assembly
An aluminum external probe housing with a 3300 XL 8 mm probe, 1 m cable and defined standoff geometry.
Product Overview
21000-34-10-20-058-04-02 is a Bently Nevada aluminum proximity probe housing assembly for externally mounting a reverse-mount probe. The assembly includes the housing architecture, probe sleeve, sealing parts and configured probe options.
Its ordering code specifies a 3300 XL 8 mm probe with connector protector and multiple approvals, a 1.0 m probe cable, a 2.0 in standoff adapter, 5.8 in probe penetration, one 3/4-14 NPT plug and a 3/4-14 NPT mounting thread.
Performance
- Provides protected external access for probe adjustment, inspection and replacement.
- Establishes the mechanical insertion path and standoff geometry for the 8 mm probe.
- Uses an aluminum housing body and the sealing arrangement defined for the 21000 family.

FAQ
Which probe is included in 21000-34-10-20-058-04-02?
Option 34 identifies a 3300 XL 8 mm probe with connector protector and the multiple-approvals execution.
What are the key mechanical dimensions of 21000-34-10-20-058-04-02?
The code specifies a 2.0 in standoff adapter and 5.8 in probe penetration.
Why does 21000-34-10-20-058-04-02 use mounting option 02?
Because a non-zero standoff adapter is specified, the official ordering rules require the 3/4-14 NPT mounting-thread option.
Is 21000-34-10-20-058-04-02 the complete electronic transducer system?
No. The matching extension cable, Proximitor Sensor and monitoring channel must still be confirmed.
What evidence should accompany a 21000-34-10-20-058-04-02 enquiry?
Send the housing label, machine mounting drawing, sleeve and penetration dimensions, sensor and cable labels, and hazardous-area documentation.
