The 21000-34-10-00-078-04-02 is a protective enclosure installed externally on a machine, containing a 3300 XL 8mm probe for monitoring vibration or displacement of rotating machinery in harsh environments.
Threaded ports for conduit connections
A probe sleeve of optional length
Optional conduit fittings
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.

Oil & Gas
Monitoring radial vibration of large centrifugal compressors by penetrating thick casings with the 198mm depth.
Petrochemical
Condition monitoring of critical feed pumps,using the aluminum housing to shield electromagnetic interference.
Hydroelectric Power
Measuring shaft runout of hydro turbines,providing IP66 protection for monitoring low-speed heavy shafts in humid conditions.
Steel & Metallurgy
Blast furnace blower protection,utilizing online maintainability to fine-tune probe gaps without disassembling large units.
Pulp & Paper
Monitoring pulper and dryer bearings,protecting probe cable connections from environmental corrosion in outdoor or high-temp areas.
Marine Engineering
Monitoring main propulsion shafting; tracking vibration and eccentricity using the rugged aluminum housing to withstand marine vibrations.
When using the 21000-34-10-00-078-04-02 aluminum housing assembly, the primary considerations are the precision of online adjustment and the physical stability of the long sleeve. First, given its 7.8-inch (198mm)penetration depth, it is critical to verify the casing wall thickness before installation to prevent mechanical collision between the probe and the rotating shaft. When fine-tuning the gap externally, monitor the bias voltage in real-time to lock it at the -10VDC linear center.Second, due to its aluminum construction, you should periodically inspect the surface for galvanic corrosion and ensure the Viton O-rings are intact to prevent lubricating oil leakage. Additionally, as this model features a 1.0-meter cable, it must be paired with a correctly lengthened 3300 XL extension cable. Finally,when used in hazardous areas, strict adherence to explosion-proof wiring and shielding/grounding protocols corresponding to its -34 multiple approvals is mandatory to ensure signal transmission stability.
It is a Bently Nevada 21000 series aluminum proximity probe housing assembly.
How to use products like the 21000-34-10-00-078-04-02?
It is screwed into the bearing housing or machine casing via its 3/4-14 NPT thread. During use, technicians can precisely set the voltage gap between the probe and the shaft externally using the adjustment mechanism at the base of the housing without disassembling the machine.
What is the primary advantage of the 21000-34-10-00-078-04-02?
The core advantage is online maintainability. It complies with the API 670 standard, allowing for probe replacement or gap adjustment while the machine is running. Its aluminum housing is rugged and effectively resists outdoor rain and sand.
Does the 21000-34-10-00-078-04-02 include a Proximitor?
No, it does not. It only includes the housing and the probe. You must separately purchase a 3300 XL Proximitor and a matching 3300 XL extension cable to form a complete measurement system.
Can the 21000-34-10-00-078-04-02 be used in hazardous areas?
Yes. The -34 option indicates that the built-in probe carries multiple agency approvals (such as CSA, ATEX, IECEx). When used with correct safety barriers, it is suitable for flammable and explosive environments.
