The 21000-34-05-00-015-04-02 is an aluminum proximity probe housing assembly belonging to the 21000 series. This complete part number signifies that it includes an internal 3300 XL 8 mm proximity probe with a connector protector and a 0.5-meter probe cable. In a hardware structure without a standoff adapter, it is equipped with a 304 stainless steel sleeve providing a penetration depth of 1.5 inches. Its conduit outlet fitting option includes only one 3/4-14 NPT threaded metal plug, and it utilizes a 3/4-14 NPT base mounting thread to connect with the machine casing.
A reverse mount proximity probe
A probe sleeve of optional length
A dome cover that screws into the body of the housing
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.
Bently Nevada 21000-34-05-00-015-04-02 serves as the core node for the physical protection of the underlying sensor. To achieve closed-loop monitoring of the rotating machinery shaft condition, after the housing assembly is rigidly fixed to the external wall of the bearing housing via the 3/4-14 NPT base thread, the 0.5-meter coaxial cable extending from the internal 3300 XL 8 mm probe cannot be routed directly over a long distance. Instead, it must interconnect with an external dedicated extension cable inside the cavity of the aluminum housing.

Oil and Gas Refining
Installed on the bearing housings of large centrifugal and rich gas compressors in refinery fluid catalytic cracking units to monitor shaft radial vibration and axial displacement online.
Thermal Power Plants
Deployed on the high-temperature bearing pedestals of main steam turbine generator sets, large boiler feed pumps, and induced draft fans to collect non-contact shaft mechanical vibration signals in real time.
Hydroelectric Power Plants
Used for vertical or horizontal bearing shaft monitoring of hydro-generator units, protecting probe cable connectors from moisture ingress in extremely damp turbine pit environments.
Oil and Gas Pipelines
Installed on the rotors of main steam turbines, main feed pumps, and condensate pumps in conventional islands, working with Proximitors to convert mechanical displacement into standard voltage signals.
Ironmaking and Metallurgical Blast Furnaces
Deployed on blast furnace top gas energy recovery turbine (TRT) power generation units and blast furnace blower sets to withstand severe environmental mechanical vibration and dust accumulation in metallurgical workshops.
Mining and Mineral Processing
Used for shaft bearing monitoring of large ball mill and semi-autogenous (SAG) mill main gearboxes and high-power exhaust fans, preventing heavy mine dust and slurry from entering the probe.
When installing and using this housing, position the probe penetration length according to the 1.5-inch specification to prevent tip collision with the rotor.
Protect the 0.5m cable during routing and secure the connector protector against water and oil. Seal the threaded connections according to standards to comply with hazardous area explosion-proof requirements.
Bently Nevada 21000-34-05-00-015-04-02 carries a CSA Type 4 environmental enclosure rating to provide low-level physical protection for shaft condition monitoring systems on large rotating machinery. This model excludes external standoff adapters and features a rigid 304 stainless steel sleeve with a factory-set mechanical penetration depth of 1.5 inches.
