The 21000-28-05-00-031-01-02 is an industrial-grade probe protective housing assembly that combines efficient maintainability with adaptability to harsh environments. It serves as a critical physical protection layer in eddy current sensor systems, with particular emphasis on ease of maintenance.
Threaded ports for conduit connections
A reverse mount proximity probe
O-rings
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. The 164818 Compact Proximity Probe Housing is also available for applications with space restrictions. Ceramic capped probes are available with the 164818 housing. Sleeve length is determined by the location in which the probe and housing are installed. The probe lead must be longer than the sleeve. Sleeve lengths longer than 304 mm (12 inches) require additional sleeve support to reduce the vibration associated with unsupported long sleeve lengths. Bently Nevada offers a probe support and oil seal (part number 37948-01) for long sleeves that must go through an inner bearing housing. We also make custom sleeve supports.

Oil & Gas Refining
The “28” reverse installation allows for the rapid replacement of core sensors without disassembling complex explosion-proof pipelines, ensuring uninterrupted oil refining production.
Gas Pipelines
It meets multiple international explosion-proof standards and is suitable for pressurization stations along the line that are remote and have an explosion risk.
Centrifuge Manufacturing
The 3.1-inch depth is suitable for the bearing housing thickness of most centrifuges, and the reverse installation greatly facilitates after-sales maintenance.
Industrial Gearbox
The “00” main body design is highly compact, allowing it to be easily installed on the outside of a gearbox where space is extremely limited.
Marine Engineering
The robust aluminum alloy or stainless steel casing can withstand the high humidity and salt spray corrosion at sea.
The "28" in the model designation specifies that the probe must be used with the Bently Nevada 3300 XL 8 mm reverse-mount probe. Standard probes (threaded at the head) cannot be inserted from the rear of the housing; forcing them in will result in damage. Before inserting the probe into a 3.1-inch (79 mm) tube, check that the probe cable connector is intact and it is recommended to use a dedicated connector protector to prevent scratches during insertion.
Option “28” means that the housing is compatible with the 3300 XL 8 mm reverse-mount probe.
Is 21000-28-05-00-031-01-02 made entirely of stainless steel?
The Bently Nevada 21000 series casings are typically made of corrosion-resistant aluminum alloy (anodized).
Can the
Yes, that's its main function.
After purchasing model 21000-28-05-00-031-01-02, will it be necessary to stop the machine and disassemble the entire casing when changing the probe in the future?
No need. That's precisely the biggest selling point of this model.
What type of equipment housing is model 21000-28-05-00-031-01-02 suitable for?
It is ideal for installation on equipment with medium-thickness housings, such as medium-sized centrifugal pumps, compact gearboxes, or bearing housings for medium-sized motors.
