Product Precautions
The 21000-16-10-00-054-04-02 is an industrial-grade, externally mounted proximity probe housing assembly pre-installed with a 3300 XL 8 mm proximity probe featuring a standard ClickLoc connector and an integrated 1.0-meter coaxial cable.
- A probe sleeve of optional length
- A reverse mount proximity probe
- A dome cover that screws into the body of the housing
Operating via the eddy current principle, the internal sensor performs micron-level precise measurements of shaft vibration, axial position, and Keyphasor references on fluid-film bearing machines. The configuration of this specific part number delivers a 5.4-inch (137 mm) probe penetration sleeve depth and a 3/4-14 NPT tapered pipe mounting thread for direct machine casing installation without a standoff adapter, complete with dedicated sealed conduit and cable gland fittings. The paramount technical advantage of this assembly is its online serviceability, enabling technicians to adjust the micro-gap calibration or completely replace the internal sensor from the outside while the machinery remains fully operational.

Oil & Gas Transmission Industry
Installed on the bearing housings of natural gas pipeline centrifugal compressors at gas transmission stations, leveraging its external locking structure to perform online micro-adjustments of axial displacement probes without shutting down or depressurizing the unit.
Petroleum Refining Industry
Deployed on high-power main air blowers in catalytic cracking units, utilizing the 5.4-inch penetration depth to pass through double-walled casings, providing reliable IP66 fluid-sealing and monitoring shaft runout within high-pressure oil mist environments.
Coal Chemical & Syngas Industry
Used in high-pressure recycle gas compressors for coal-to-liquids projects within hazardous zones filled with toxic, flammable gases, allowing technicians to safely extract and replace a damaged internal vibration sensor from the outside without casing disassembly.
Nuclear Power Generation
Used on the low-pressure rotor section of 1000MW conventional island steam turbine generator sets, leveraging its compact configuration with no standoff adapter to thread directly onto the bearing pedstal exterior for vibration monitoring.
Mining & Heavy Mineral Processing
Installed on the high-speed input shaft housings of heavy-duty SAG mill drive gearboxes, where the high-strength aluminum and stainless steel composite enclosure prevents damage to the sensor from flying rock debris and severe mechanical impacts.
Pulp & Paper Industry
Used on the main shafts of wire section drive gearboxes in modern paper mills, where the protective enclosure stops high-pressure water washdowns and high-temperature white water splashes from permeating electrical junctions, eliminating sensor false alarms.
During installation and online maintenance, technicians must strictly follow intrinsically safe codes and mechanical torque specifications for the 3/4-14 NPT tapered pipe threads to prevent stripping the aluminum housing. Given its 5.4-inch penetration depth, when extracting, adjusting the internal probe gap (typically calibrated to -10 VDC), or replacing the sensor while the machinery is running, the adjustment must be rotated extremely slowly to avoid catastrophic physical contact between the probe tip and the high-speed rotating shaft.
Furthermore, verify that static seals like O-rings at the casing interface remain intact, and securely tighten the external conduit and cable gland combination to maintain its CSA Type 4 (IP66) weatherproof, dustproof, and oil-leakage protection ratings.

Technical notes
Bently Nevada 21000-16-10-00-054-04-02 working via the eddy current principle, the internal probe performs micron-level precise measurements of shaft vibration, axial position, and Keyphasor references fully in compliance with the API 670 Standard. The paramount technical advantage of this assembly is its online serviceability—it enables technicians to adjust the micro-gap calibration (typically to -10 VDC) or completely replace the internal sensor from the outside while the machinery remains fully operational, serving as a critical asset protection component for continuous-process heavy industries.
FAQ View All FAQ
-
What kind of device is Bently Nevada 21000-16-10-00-054-04-02?It is an industrial-grade, externally mounted proximity probe housing assembly (aluminum body with a 304 stainless steel sleeve) pre-installed with a 3300 XL 8 mm sensor probe.
-
What is the primary purpose of 21000-16-10-00-054-04-02?It is installed on the exterior of large machinery to shield internal precision probes from harsh environments, allowing the probe to perform non-contact measurements of micron-level shaft vibration, displacement, and speed.
-
How do you correctly install the 21000-16-10-00-054-04-02 assembly?It must be installed while the machinery is completely at rest, threading the assembly into the casing via the 3/4-14 NPT threads, adjusting the internal probe depth, and locking it once the Proximitor output bias voltage matches the standard value on a multimeter.
-
