Installation & Maintenance Notes
The 21000-16-10-00-126-04-02 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
The robust aluminum casing provides reliable protection for the sensitive 8 mm sensor element against heavy industrial dust, lubricant splashes, and corrosive ambient environments, ensuring continuous operational uptime and preventing unpredicted machinery trips in critical process industries. 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.
Because the configured penetration depth is 12.6 inches, which exceeds the 304 mm (12-inch) mechanical threshold, additional internal sleeve support is mandatory to mitigate operational vibration associated with unsupported long lengths. For installations routing through an inner bearing housing, a Bently Nevada probe support and oil seal (Part Number 37948-01) or custom sleeve supports are applicable.

Oil & Gas Refining
High-precision radial vibration and axial thrust monitoring deep within the internal bearings of high-speed centrifugal compressors, utilizing the 12.6-inch sleeve to penetrate thick multi-layered casings.
Thermal Power Generation
Micro-level shaft vibration and thermal eccentricity measurement within main steam turbine bearing housings, requiring extended sleeve lengths to reach the internal shaft surface safely from the exterior housing.
Hydroelectric Power Generation
Radial runout and low-frequency shaft vibration tracking on large vertical guide bearings, leveraging the long sleeve to pass through deep outer structural components.
LNG Liquefaction & Regasification
Precision vibration tracking on cryo-machinery, where the 12.6-inch sleeve isolates the active sensor head from the external environment while penetrating deep insulation layers.
Iron & Steel Metallurgy
Monitoring heavy-duty, high-vibration air supply systems to track unbalance caused by constant industrial dust, utilizing internal sleeve supports to eliminate vibration on the 12.6-inch length.
When using the 21000-16-10-00-126-04-02, since its sleeve length is 12.6 inches (320 mm) and exceeds the 12-inch vibration-free threshold, an additional sleeve support (such as part number 37948-01) must be installed to eliminate mechanical vibrations.
Ensure the internal probe lead is longer than 12.6 inches for a proper connection. Furthermore, because this model carries multiple hazardous area approvals including ATEX/IECEx/CSA (Option -04), certified explosion-proof cable glands must be used during installation in classified areas, and the aluminum housing's O-rings must be inspected periodically to prevent oil leakage or environmental moisture ingress.

Technical notes
This API 670/CSA Type 4 aluminum housing assembly integrates a 3300 XL 8 mm probe (multi-approvals) with a 1.0-meter cable. Configured with a 12.6-inch penetration depth and no standoff adapter, it utilizes a 3/4-14 NPT mounting thread and one 3/4-14 NPT plug. Supplemental internal sleeve support applies to this 12.6-inch length to mitigate operational vibration.
