The 21000-34-05-00-022-03-02 is an Aluminum Proximity Probe Housing Assembly with Canadian Standards Association (CSA) approvals. It carries an explosion-proof rating for hazardous areas and applies to intrinsically safe installations. The housing functions as a certified CSA Type 4 enclosure and maintains full compliance with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings.
Threaded ports for conduit connections
Optional conduit fittings
A dome cover that screws into the body of the housing
This specific configuration incorporates a 3300 XL 11 mm proximity probe with multiple hazardous area approvals, featuring a 0.5-meter (20-inch) probe cable length. The assembly features a no-standoff adapter configuration (0.0 inches) and provides a precise probe penetration depth of 2.2 inches. For mechanical installation, it utilizes a 3/4-14 NPT mechanical mounting thread and includes a fittings configuration of one 3/4-14 NPT elbow.
The sleeve length of this assembly depends directly on the location in which the probe and housing are installed, ensuring the probe lead remains longer than the sleeve. For applications where unsupported sleeve lengths exceed 304 mm (12 inches), additional sleeve support is mandatory to mitigate vibration. For installations routing through an inner bearing housing, a Bently Nevada probe support and oil seal (Part Number 37948-01) or custom sleeve supports can be utilized.

Oil & Gas Upstream & Midstream
Used on natural gas compressor packages along long-distance pipelines to monitor rotor shaft vibration, preventing mechanical damage caused by pipeline pressure fluctuations.
Thermal Power Generation
Used on the external bearing pedestals of large steam turbine-generator sets to precisely measure main shaft vibration and eccentricity through the casing.
Nuclear Power Generation
Used on reactor main feedwater pumps and coolant circulation pumps to monitor rotor operating status in harsh environments near high temperature, high pressure, and radiation borders.
Hydroelectric Power Generation
Installed on the guide bearings of large hydro-generator units to measure radial vibration and runout of the turbine shaft, preventing hydraulic imbalance from damaging equipment.
Iron & Steel / Metallurgy Industry
Vibration monitoring of cryogenic machinery operating under extreme sub-zero temperatures, ensuring the integrity of the external probe housing housing.
Mining & Coal Industry
Used on primary mine ventilation fans and coal gasification units; its explosion-proof housing allows safe operation in coal mine sites containing methane gas while delivering speed and vibration signals.
When installing or adjusting this housing assembly, disconnect the cable before rotating the sleeve to prevent twisting and damaging the signal wire. Use a multimeter to monitor voltage and precisely calibrate the initial probe gap.
Ensure the dome cap and NPT connections are securely tightened to maintain strict explosion-proof and waterproof sealing. Lastly, route the cable through a metal conduit and keep it isolated from high-power interference sources to ensure precise and stable vibration measurements.
The Bently Nevada CA21000-34-05-00-022-03-02 is an external proximity probe housing assembly featuring a reverse-mount 3300 XL 8mm probe with M10×1 threads and a 0.3-meter cable. Utilizing a 2.2-inch stainless steel casing, it provides an externally adjustable, hazardous-area certified, and IP-rated weatherproof enclosure for precise vibration and displacement monitoring on rotating machinery where internal mounting is unavailable.
It is an External Proximity Probe Housing Assembly (containing a 3300 XL 8mm probe) manufactured by Bently Nevada, primarily used for vibration, displacement, and speed monitoring of industrial rotating machinery.
What is the primary operating principle of 21000-34-05-00-022-03-02?
It utilizes the eddy current effect. When the probe tip receives a high-frequency current, it generates eddy currents on the target metal shaft. Changes in shaft distance cause impedance variations in the probe coil, which are converted into voltage signals.
How to correctly install and use 21000-34-05-00-022-03-02?
Mount the housing base onto the machine casing, adjust the internal casing to point the probe perpendicularly at the shaft, monitor the gap voltage using a multimeter, lock the nuts once the target value is reached, and close the external dome cap.
