SECTION 01
Product Description
The Bently Nevada 21000-16-10-00-076-03-02 is a 21000 aluminum proximity probe housing assembly for mounting a reverse-mount 3300 XL 8 mm probe outside a machine case. It holds the probe body, protects the cable transition and establishes a conduit-entry point while the probe tip faces the monitored target surface.
Installed through its 3/4-14 NPT machine thread, the 21000-16-10-00-076-03-02 uses a stainless steel sleeve to carry the probe through the case. The C00 code removes the standoff adapter, while the D076 sleeve position places the probe at a 7.6 in penetration; the 1.0 m lead then returns through the housing toward the connected transducer-system wiring.
At the cable exit, the 21000-16-10-00-076-03-02 combines the housing's threaded conduit ports with option E03. That fitting set supplies one plug, one 3/4-14 to 1/2-14 NPT reducer and a cable seal grip, so unused entry space can be closed while the outgoing cable passes through a sized sealing grommet.

SECTION 03
Probe Positioning Geometry
The mechanical stack of 21000-16-10-00-076-03-02 begins at the 3/4-14 NPT machine thread and continues directly into the sleeve because this configuration has no standoff adapter. The probe position remains adjustable within the stated D-dimension range before the thread and sleeve are secured.
7.6 inspecified penetration
No standoff
C00 removes the optional adapter, so dimension C contributes no added length.
D076 sleeve position
The ordering code sets the nominal probe penetration at 7.6 in (193 mm).
±0.5 in adjustment
Option D provides a 13 mm (±0.5 in) adjustment range for the probe position.
SECTION 04
Housing Seal and Sleeve Limits
Protected mechanical route
The 21000-16-10-00-076-03-02 uses the housing, O-rings, thread seal and sleeve as one physical boundary around the reverse-mount probe and its lead.
Aluminum and stainless steel
The 21000 body is aluminum, while the probe sleeve is 304 stainless steel.
Seal temperature boundary
The probe range extends to -51 °C, but temperatures below -34 °C can prematurely damage its pressure seals.
Long-sleeve support rule
Additional sleeve support is required only when the combined C plus D penetration exceeds 12 in (300 mm).
Cable length relationship
The probe lead must be longer than the sleeve; the B10 code supplies 1.0 m of probe cable for this configuration.
SECTION 05
Frequently Asked Questions
Does 21000-16-10-00-076-03-02 include the proximity probe?
Yes. The A16 position specifies a 3300 XL 8 mm reverse-mount probe, and the B10 position specifies a 1.0 m probe cable for 21000-16-10-00-076-03-02.
Is 21000-16-10-00-076-03-02 the CSA explosion-proof CA21000 version?
No. 21000-16-10-00-076-03-02 begins with the standard 21000 prefix. CSA explosion-proof configurations use the CA21000 prefix and separate approval-dependent ordering rules.
What machine mounting thread is supplied on 21000-16-10-00-076-03-02?
The F02 position gives 21000-16-10-00-076-03-02 a 3/4-14 NPT mounting thread at the sleeve-to-machine connection.
Does the sleeve on 21000-16-10-00-076-03-02 require additional support?
The C00 and D076 positions produce a 7.6 in penetration length. The additional-support requirement begins when C plus D exceeds 12 in, so 21000-16-10-00-076-03-02 does not reach that stated threshold.
How is the probe lead routed out of 21000-16-10-00-076-03-02?
The 1.0 m probe lead returns through the housing and conduit path. The E03 fitting set for 21000-16-10-00-076-03-02 provides a plug, an NPT reducer and a cable seal grip with three grommet ranges for the outgoing cable.
What low-temperature limit matters for the probe seals in 21000-16-10-00-076-03-02?
The 3300 XL 8 mm probe has a -51 °C operating and storage limit, but exposure below -34 °C can prematurely damage its pressure seals. Both limits must therefore be considered for 21000-16-10-00-076-03-02.
