21000-34-05-00-022-03-02

Spare Part Number

PN21000-34-05-00-022-03-02

Product Information:

The 21000-34-05-00-022-03-02 is an external mounting protective housing assembly for the 21000 series metal eddy current probes manufactured by Bently Nevada. This assembly is a complete mechanically integrated hardware package fully compliant with API 670 standards, specifically designed for bearing housing surfaces in large steam turbines, centrifugal compressors, and various high-pressure industrial pumps.

The core design concept of the 21000-34-05-00-022-03-02 is to allow on-site maintenance personnel to safely perform gap calibration, disassembly, cleaning, or complete replacement of the internal probe directly from the outside of the machine without stopping the machine or disassembling the machine casing, greatly simplifying the daily dynamic monitoring and maintenance process for rotating machinery. From its highly customized selection coding breakdown, this assembly belongs to a classic explosion-proof configuration with a short sleeve and pre-installed probe.

The 21000-34-05-00-022-03-02 enclosure boasts an IP66 airtight seal, effectively preventing the penetration and corrosion of fragile internal coaxial joints by high-concentration industrial dust, splashing water, salt spray, and highly corrosive gases. Its robust overall structure perfectly withstands the high pressure of internal processes, effectively preventing lubricant leakage from the bearing housing.

1.High Safety and Explosion-Proof Rating: Option A = 34 indicates that its built-in 3300 XL 8mm probe has passed multiple mainstream explosion-proof certifications (such as ATEX, IECEx, CSA, etc.), making it ideal for hazardous areas (Class I Zone 1 / Zone 0, 1) where flammable and explosive gases are present, such as in the oil, gas, and chemical industries.
2.No Extension Joints and Short Sleeve: The absence of extension joints (Option 00) and a short penetration depth of 2.2 inches (approximately 56mm) indicate that this assembly is designed for bearing housings with extremely thin housings and limited external space. Furthermore, the extension joint-free design lowers the center of gravity of the external junction box, effectively resisting high-frequency vibrations from field machinery.
3.Complete Cable Sealing Protection: Option E = 03 is a fully functional connector assembly. In addition to sealing unused sockets, it provides cable seals (joints) that tightly lock and seal outgoing extension cables, ensuring the entire aluminum junction box achieves NEMA 4 / IP66 waterproof and dustproof performance.
