Descripción del producto
21000-00-00-15-226-03-02 Bently Nevada Proximity Probe Housing Assemblies For External Mounting Of Proximity Probes
The Bently Nevada 21000-00-00-15-226-03-02 is an all-metal, aluminum-body external proximity probe housing assembly engineered to protect proximity sensors on heavy machinery. This specific configuration is shipped without an integrated internal probe or cable, allowing operators to deploy or retrofit their existing sensors into a ruggedized, API 670-compliant enclosure. By housing the sensor externally, it resolves the financial bottleneck of forced plant shutdowns for routine instrumentation tuning, allowing technicians to swap probes or adjust target clearances entirely from the outside while the machinery remains fully operational. It is ideal for large-footprint rotating machinery, such as steam turbines, industrial fans, and centrifugal compressors, that are wrapped in heavy thermal insulation and exposed to high outdoor vibrations.
Engineer's Note
"When installing a 21000 series housing with an extra-long sleeve like this 22.6-inch model, our vibration group notes that unsupported sleeves exceeding 12 inches (304 mm) can develop mechanical resonance from fluid flow or case vibration. For this specific -226 configuration, you must install an intermediate external sleeve support or use Bently Nevada's dedicated internal oil seal support (such as part number 37948-01). This simple additional step dampens high-frequency sleeve whip and ensures your proximity readings reflect actual shaft motion rather than housing shake."
Project Case
"This exact 22.6-inch extended 21000-00-00-15-226-03-02 empty housing arrangement was successfully selected and retrofitted onto a series of large-diameter double-suction cooling water pumps. By using the 1.5" standoff and long penetration sleeves, the facility managed to run existing 3300 XL sensors through deep internal water-jacket cavities, keeping the probe electronics safe from moisture while allowing external gap calibration while running."
Custom FAQ
Q: Can I install a 3300 XL 8mm reverse-mount probe into this empty housing later?
A: Yes. The housing accommodates all standard Bently Nevada 3300 XL 8mm, 11mm, or NSv reverse-mount probe profiles. Simply choose the matching internal adapter sleeve bushings to lock your sensor into the 22.6-inch track.
Q: What specific items are included under the -03 Fitting Option?
A: The -03 option provides a full terminal entry kit containing one 3/4-14 NPT steel blanking plug, one 3/4-14 to 1/2-14 NPT stepping reducer, and a cable seal grip equipped with three interchangeable compression rubber grommets fitting 1/8", 1/4", and 5/16" cable diameters.
Q: Is this aluminum housing recommended for use on open-deck offshore oil platforms?
A: Although the assembly holds a robust CSA Type 4 weatherproof seal, salt spray can pit anodized aluminum over several years. For raw coastal or offshore marine environments, we recommend specifying the all-stainless steel 24701 version instead.
