The 21000-28-05-00-021-03-02 is a highly compact, explosion-proof probe mounting housing assembly. Specifically designed for precision machinery with extremely limited installation space, its key feature is a "zero-length" body design (option 00), allowing the housing to be mounted flush against the unit surface. It boasts a short penetration depth of 2.1 inches (53 mm), perfectly accommodating 8 mm reverse-mount probes.
An optional standoff adapter
A reverse mount proximity probe
Optional conduit fittings
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.

Chemical Process Pumps
The housing is screwed directly onto the pump's bearing cover, and an 8 mm probe is installed inside to monitor the axial movement of the shaft.
Compact Industrial Motors
Installed on end caps at both ends of the motor, used to monitor the radial vibration of the rotor.
High-Speed Gearboxes
Technicians can adjust the probe gap from the outside through the housing and determine whether the gears are worn or the bearings are failing by monitoring voltage changes, without having to drain the gear oil.
Aerospace Test Cells
Installed on the housing of a high-speed turbopump or fuel regulator, it monitors the stability of the shaft at ultra-high speeds.
Municipal Water & Drainage
The sealed structure of the housing, combined with explosion-proof certification, effectively prevents moisture from penetrating into the sensor core, ensuring that the monitoring system does not give false alarms during critical moments in the flood season.
The "02" at the end of the model number indicates explosion-proof certification. Due to the short housing, the threaded stress area is relatively small. When installing "05" (3/4 NPT thread), rust on the machine opening must be thoroughly cleaned, and a conductive anti-seize compound must be used. This is not only for sealing but also to ensure electrical connection (grounding) between the probe housing and the machine housing, preventing static electricity buildup. Although it is explosion-proof and sealed, oil and condensation can easily accumulate because it is usually installed low and close to the machine body. The outgoing cable must have a downward curve (drip bend) to prevent liquid from directly pressing the seal along the hose.
"00" indicates that the main body length of the casing is 0 inches.
In model 21000-28-05-00-021-03-02, what are the mandatory requirements for the matching probe for the
The "28" designation indicates that the housing must be used with a 3300 XL 8 mm reverse mount probe.
If 21000-28-05-00-021-03-02 is installed on an offshore unit with explosion-proof requirements, what protective function does the
"02" indicates that the product has multiple explosion-proof certifications from North America (CSA) and internationally (ATEX/IECEx).
In model 21000-28-05-00-021-03-02, is it necessary to wrap Teflon tape around the thread corresponding to option
For the 3/4-14 NPT tapered pipe thread represented by "05", it is not recommended to use ordinary PTFE tape, especially in explosion-proof areas.
If the 21000-28-05-00-021-03-02 cable is installed in a vertical position, how can I prevent moisture from entering the cable?
During installation, technicians must connect an explosion-proof conduit or cable seal fitting that meets IP66/IP67 rating at the "03" interface.
