Product Precautions
The 21000-16-10-00-167-04-02 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 physical configuration of this specific part number delivers an extra-long 16.7-inch (424 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.
Because the sleeve length exceeds 12 inches (304 mm), an additional sleeve support is required to reduce the vibration associated with unsupported long sleeve lengths. The paramount technical advantage of this assembly is its online serviceability, enabling safe insertion, micro-gap calibration adjustment (typically to -10 VDC), or complete replacement of the internal sensor from the outside while the machinery remains fully operational.

Thermal Power Generation
Installed on the high-pressure double-shell casings of large 1000MW conventional island steam turbines, using the 16.7-inch extra-long sleeve to penetrate the vacuum gap between casings to precisely monitor main shaft radial vibration.
LNG Liquefaction & Storage
Used on high-pressure mixed refrigerant compressors within large LNG cold boxes, providing fully sealed, extra-long physical isolation and intrinsically safe explosion-proof protection for the sensors.
Coal Gasification & Synthetic Ammonia
Used on high-pressure CO2 compressors and reciprocating pumps where thick machine walls and toxic high-pressure environments exist, enabling external gap adjustments without teardown and high-grade explosion-proof sealing.
Nuclear Power
Used on the thick double-walled protective casings of reactor main feedwater pumps and auxiliary steam turbines in nuclear power plants, fulfilling API 670 standards for highly reliable, long-term external mechanical protection.
Hydroelectric & Pumped Storage Power
Installed on deeply buried lower guide bearings or large-capacity pump runout measurement locations of vertical hydro-generators, penetrating thick outer seal structures to measure dynamic shaft runout.
Geothermal Steam Power Generation
Used on low-pressure corrosive steam turbine casings of geothermal generator sets, utilizing the long stainless steel sleeve and explosion-proof box to isolate high-concentration H2S gas, securing the vibration monitoring loop.
Given its extra-long 16.7-inch (424 mm) penetration depth, an additional internal sleeve support must be installed inside the machine casing to suppress mechanical vibrations associated with the unsupported long sleeve length.
During external installation and online maintenance, strict adherence to intrinsically safe codes and torque specifications for the 3/4-14 NPT tapered pipe threads is required to prevent stripping the aluminum housing. When extracting, adjusting the internal probe gap (typically calibrated to -10 VDC), or replacing the sensor while the machinery is running, the axial insertion and rotation must be executed extremely slowly to avoid catastrophic physical contact between the extra-long sleeve/probe tip and the high-speed rotating shaft.
Furthermore, verify that static seals like O-rings at the 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.
