Description
The Bently Nevada 21000-34-05-00-040-03-02 is a stainless steel proximity probe housing assembly for externally mounting proximity probes on rotating machinery in corrosive and hazardous industrial environments. The 21000-34-05-00-040-03-02 consists of a dome cover that screws into the body of the housing, threaded ports for conduit connections, a probe sleeve of optional length, O-rings, a reverse mount proximity probe, a thread seal, and a cable seal grip with grommets. This comprehensive assembly of the 21000-34-05-00-040-03-02 provides a complete solution for protecting and positioning the proximity probe in demanding industrial environments.
The 21000-34-05-00-040-03-02 features a stainless steel construction that provides superior corrosion resistance compared to aluminum housings, making it ideal for offshore platforms, chemical plants, and other environments where corrosive atmospheres are present. The 21000-34-05-00-040-03-02 includes a 3300XL 8mm reverse mount proximity probe with 3/8-24 UNF threads, enabling external installation from the exterior of the machine case with the probe tip extending inward toward the target surface.

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.
The 21000-34-05-00-040-03-02 features a 4.0-inch (101.6 mm) probe sleeve length with adjustable probe penetration, providing an adjustment range of ±0.5 inch (13 mm) to accommodate various machine case thicknesses and mounting requirements. For probe penetration lengths between 1.0 and 2.0 inches, it may be necessary to counter bore the machine case to reduce probe side view or rear view, as noted in the installation guidelines for the 21000-34-05-00-040-03-02.
The 21000-34-05-00-040-03-02 is rated as a CSA explosion-proof enclosure and is certified as a CSA Type 4 enclosure, providing protection against dust, water, and hazardous atmospheres. The 21000-34-05-00-040-03-02 is fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probes, ensuring it meets the stringent requirements of the oil and gas and petrochemical industries for machinery condition monitoring.

Prepare the Housing: Ensure the housing O-rings and thread seals are in good condition.Probe Insertion: Insert the proximity probe into the probe sleeve of the housing assembly.
Mounting the Housing: Screw the housing assembly into the machine case (or a standoff adapter if your code requires one) using the designated mounting threads.
Depth Adjustment: Adjust the probe penetration depth by threading the probe in or out to achieve the correct gap relative to the target machine shaft.
Technical notes
The 21000-34-05-00-040-03-02 features a 3/4-14 NPT mounting thread for secure attachment to the machine case. The cable seal grip included with the 21000-34-05-00-040-03-02 accommodates cable sizes from 1/8 to 3/8 inches, ensuring proper sealing and strain relief for the probe cable. If the probe penetration length of the 21000-34-05-00-040-03-02 exceeds 300 mm (12 inches), additional sleeve support must be added near the probe to prevent resonance from occurring.
