Features:
- External Housing Protection for Machine Casing Mounts with CSA Explosion-Proof Rating
- Houses 3300 XL 8mm Reverse Mount Probe with 0.5m Cable and 13.0-Inch Sleeve Penetration
- Features All-Aluminum Construction with 3/4-14 NPT Mounting Thread and Plug Fitting
The Bently Nevada 21000-28-05-00-130-04-02 Proximity Probe Housing Assembly serves as an all-metal external protective enclosure designed to securely accommodate proximity sensors mounted on industrial machinery. The aluminum body, combined with its threaded dome cover, O-rings, and thread seal, seals the internal sensor components and cable connections against environmental elements while enabling physical vibration and displacement measurements.
The 21000-28-05-00-130-04-02 performs vital protective functions for the transducer system, serving as a key hardware component that directly enables safe and accurate proximity monitoring in hazardous areas. It carries Canadian Standards Association (CSA) approvals, certifying it as explosion-proof for hazardous locations. The entire assembly secures directly to the machine via a 3/4-14 NPT mounting thread and includes one 3/4-14 NPT plug with no standoff adapter configured.
For external mounting applications, the 21000-28-05-00-130-04-02 assembly facilitates sensor installation and maintenance without requiring complete disassembly of the machine housing. During operation or routine inspection, technicians can access the internal 3300 XL 8mm reverse mount probe and perform gap adjustments directly through the sleeve assembly. The threaded conduit ports and supplied 3/4-14 NPT plug ensure that the enclosure maintains its structural integrity and explosion-proof sealing around the probe's cable connection.
The 21000-28-05-00-130-04-02 Bently Nevada Proximity Probe Housing Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Machine Components Monitored: It is installed on steam turbines, gas turbines, centrifugal compressors, large industrial pumps, and gearboxes.
- Vibration and Position Tracking: The housing preserves precise target-to-shaft gap settings required to monitor radial vibration, axial thrust position, and shaft speed.
- External Maintenance Access: It allows engineers external access to the proximity probe and its extension cable. This permits routine gap adjustments or complete probe replacements without requiring the disassembly of the machine, minimizing plant downtime.
- Mechanical Gap Adjustment: Calibration is performed by manually rotating the probe within its reverse-mount sleeve. Technicians monitor the voltage output using a digital multimeter or a calibration instrument to match the correct DC bias voltage (typically -10 VDC for a centered gap).
- Sleeve Structural Support: Because this configuration dictates a long 13.0-inch penetration depth (exceeding 12 inches), it requires additional internal structural sleeve support to reduce the vibration associated with unsupported long sleeve lengths.
- Transducer System Pairing: The 3300 XL 8 mm probe must be wired back to its paired 3300 XL Proximitor Sensor. Any digital programming is conducted on the downstream machinery protection monitor (such as the Bently Nevada 3500 series rack), where users configure alert/trip setpoints and input scale factors.
- API 670 Compliance: Both housings are certified as CSA Type 4 enclosures and are fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings.
- Hazardous Area Approvals: The suffix code "-28" specifies a probe bundle carrying multiple international agency certifications. The housing assembly itself is rated explosion-proof for Class I, II, and III, Divisions 1 and 2 locations under Canadian Standards Association (CSA) guidelines.
- Environmental Sealing: The enclosure is certified to CSA Type 4 / IP66 ratings, ensuring it is fully dust-tight and rainproof against high-pressure water spray from any direction.
- Material Compliance: The assembly adheres to the RoHS Directive for hazardous materials restriction.
