The 21000-34-10-00-071-04-02 is an external protective enclosure that houses a 3300 XL 8mm probe, specifically designed for monitoring vibration or displacement of rotating machinery in harsh environments.
A dome cover that screws into the body of the housing
A probe sleeve of optional length
A reverse mount proximity probe
The 21000, 24701, and 164818 Proximity Probe Housing Assemblies are available with Canadian Standards Association (CSA) approvals. They are rated explosion proof for hazardous areas.You can order hazardous area approved proximity probes with 21000 aluminum and 24701 stainless steel housings for intrinsically safe applications. Both housings are certified as CSA Type 4 enclosures and are fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings.

Air Separation
Monitoring turboexpanders,utilizing 3300 XL technology to precisely measure micron-level shaft vibration at high speeds.
Pulp & Paper
Monitoring pulper and dryer bearings,protecting probe cable connections from environmental corrosion in outdoor or high-temp areas.
When using the 21000-34-10-00-071-04-02 aluminum housing assembly, the primary considerations are online adjustment safety and physical installation compatibility. Given its 7.1-inch (180mm) penetration depth, it is crucial to verify internal casing dimensions before installation to prevent collision between the probe and the rotating shaft; when fine-tuning the gap via the external nut during operation, monitor the bias voltage in real-time to lock it at the -10VDC linear center. Additionally, considering the limitations of aluminum housing in highly corrosive chemical environments, periodically inspect surface integrity and the condition of Viton O-rings to prevent lubricating oil leakage. Finally, ensure the use of a correctly matched 3300 XL extension cable and strictly adhere to the electrical grounding protocols corresponding to its -34 multiple approvals in hazardous areas.
It is a Bently Nevada 21000 series aluminum proximity probe housing assembly. It is a metal protective enclosure installed externally on a machine, housing a 3300 XL 8mm probe to monitor vibration or displacement of rotating machinery.
How to use products like the 21000-34-10-00-071-04-02?
It is installed onto the bearing housing via a 3/4-14 NPT thread. During operation, technicians can fine-tune the voltage gap between the probe and the shaft externally using the adjustment mechanism at the base of the housing without disassembling the casing.
What is the difference between 21000-34-10-00-071-04-02 and the 31000 series?
The primary difference is the material. The 21000 series uses an aluminum housing, whereas the 31000 series uses PPS (Polyphenylene Sulfide). The 21000 is suitable for standard industrial environments, while the 31000 is better for highly corrosive chemical environments.
What should be noted during the maintenance of the 21000-34-10-00-071-04-02?
You should periodically check the aluminum housing for signs of galvanic corrosion and ensure the sealing O-rings are intact to prevent lubricating oil from leaking from the bearing box into the housing.
What is the protection rating of the 21000-34-10-00-071-04-02?
It carries IP66 and CSA Type 4 ratings. This means it is completely dust-tight and can resist powerful industrial water jets and heavy rain.
