This robust aluminum housing assembly provides a secure, explosion-proof enclosure for proximity probes, facilitating precise radial vibration and axial position measurements on high-speed turbines, compressors, and motors. Engineered for high-reliability scenarios, it allows for seamless probe adjustment and replacement without machine disassembly, directly supporting Turbine Supervisory Instrumentation (TSI) accuracy. By isolating the sensor from harsh external elements while maintaining rigid mechanical alignment, this housing ensures that the Bently Nevada 3500 system receives stable, high-fidelity signals necessary for preventing catastrophic asset failure and optimizing maintenance intervals.\u003c\/p\u003e\n\u003ch2 data-path-to-node=\"8\"\u003eModel Configuration Analysis\u003c\/h2\u003e\n\u003ch3 data-path-to-node=\"9\"\u003e21000 - Proximity Probe Housing Series\u003c\/h3\u003e\n\u003cp data-path-to-node=\"10\"\u003eThe 21000 series is the foundational aluminum housing designed for global industrial applications requiring hazardous area certifications and rugged environmental protection.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"11\"\u003e-33-10-00 - Mounting and Thread Geometry\u003c\/h3\u003e\n\u003cp data-path-to-node=\"12\"\u003eThe \"-33\" indicates a 3.3-inch unthreaded sleeve length, allowing the probe to bypass thick insulation or casing walls.

Rotate the probe sleeve until the Proximitor Sensor output registers approximately -10.0 Vdc, ensuring the sensor operates in the center of its linear region. Apply a high-quality thread lubricant to the 3\/4-14 NPT housing threads to prevent seizing in high-heat environments. Always verify that the flexible conduit has sufficient slack to accommodate machine thermal expansion; failure to do so can strain the probe lead and introduce signal noise into the DCS or 3500 rack.\u003c\/p\u003e\n\u003ch2 data-path-to-node=\"21\"\u003eCritical Environment Performance\u003c\/h2\u003e\n\u003cp data-path-to-node=\"22\"\u003eThe 21000-33-10-00-087-04-02 excels where standard mounts fail. Its anodized aluminum construction resists oxidation and chemical exposure, maintaining an airtight seal against oil mist and moisture. This housing provides the mechanical damping required to eliminate parasitic vibrations that could lead to \"False Trips\" in systems like Honeywell Experion PKS. By ensuring a rigid, fixed distance between the probe and the shaft, it provides the sub-micron resolution needed for predictive diagnostics in high-pressure steam and gas turbine applications.\u003c\/p\u003e\n\u003ch2 data-path-to-node=\"23\"\u003eOrdering info\u003c\/h2\u003e\n\u003cul data-path-to-node=\"24\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"24,0,0\"\u003eOne (1) Brand New Bently Nevada 21000 Aluminum Housing.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"24,1,0\"\u003eInternal adjustable probe sleeve (8.7 inch total length).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"24,2,0\"\u003eSealing O-ring and gasket kit for environmental protection.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"24,3,0\"\u003eLocking nut for secure probe positioning.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"24,4,0\"\u003eManufacturer's Certificate of Conformance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 data-path-to-node=\"25\"\u003eShipping \u0026amp; Global Dispatch\u003c\/h2\u003e\n\u003cp data-path-to-node=\"26\"\u003eDelivery time: 3-5 days when payment finish through our preferred carriers DHL, FEDEX, or UPS.
