Bently Nevada 21000-15-10-00-166-03-02 21000 Proximity Probe Housing Assembly
All-metal external probe housing with 16.6 in penetration
Product Description
21000-15-10-00-166-03-02 is an all-metal Bently Nevada 21000 proximity-probe housing assembly. It combines an aluminum body with a 304 stainless-steel sleeve to protect and position a reverse-mount probe at the machine casing.
The complete code retains legacy probe option 15, a 1.0 m probe cable, no standoff adapter and a 16.6 in penetration dimension. Fitting option 03 adds a plug, reducer and cable-seal grip, while the mounting interface is 3/4-14 NPT.
The long sleeve selection makes mechanical support important for 21000-15-10-00-166-03-02. Sleeves extending beyond 12 in require support near the probe to prevent resonance, and the final probe gap is set only after the housing is secured.

Long-Sleeve Housing Design
The housing moves the probe connector and cable termination outside the machine case while the stainless-steel sleeve controls the insertion path. The aluminum enclosure provides a removable cover and a conduit entry for field access.
A 16.6 in penetration is combined with the 1.0 m probe lead and option-03 fitting hardware. The resulting assembly keeps the probe mechanically supported and gives maintenance personnel access to the connection without opening the machine casing.
Extended Penetration Installation
Extended Penetration Installation in practice
Prepare a 3/4-14 NPT mounting port and confirm that no standoff adapter is required. Thread the housing into the casing, align the conduit entry, and position the sleeve so the probe reaches the intended target without side contact.
Add support near the probe because the selected sleeve length exceeds 12 in. Route the 1.0 m cable through the option-03 seal grip and reducer, close the housing after checking the connector, then set the probe gap and verify the associated monitor channel.
Frequently Asked Questions
Why can the long sleeve on 21000-15-10-00-166-03-02 vibrate even when the housing is tight?
The selected 16.6 in penetration exceeds the 12 in length at which added support near the probe is required. Install that support without forcing the sleeve sideways, then confirm the probe still faces the target and the channel remains stable.
What should be reviewed if the probe in 21000-15-10-00-166-03-02 cannot reach the target?
This configuration uses a 16.6 in penetration with no standoff adapter. Compare the casing port, sleeve path and target location with the installation dimensions before moving the housing or selecting a different penetration code.
How should oil found inside 21000-15-10-00-166-03-02 be addressed?
Inspect the cover, conduit entry, option-03 cable seal grip and the sleeve interface before cleaning and closing the housing. Do not return the point to service until the cable connection is dry and a stable gap voltage is confirmed.
Can legacy probe option 15 in 21000-15-10-00-166-03-02 be replaced using only the 21000 housing dimensions?
No. Keep option 15 tied to the installed probe, extension cable, Proximitor Sensor and monitor channel because housing fit alone does not establish electrical compatibility.
What checks help resolve an unstable reading after 21000-15-10-00-166-03-02 has been replaced?
Confirm sleeve support, connector condition, cable sealing and the absence of probe-to-sleeve contact. Set the gap from the live channel and prove the monitor response before changing machine alarm values.
