Bently Nevada 21000-16-05-15-085-03-02 Proximity Probe Housing Assembly

Product Introduction

The Bently Nevada 21000-16-05-15-085-03-02 is a comprehensive proximity probe housing assembly. It combines a 3300 XL 8 mm probe with a protective housing and necessary fittings. This assembly simplifies installation and ensures reliable probe performance. The housing protects the probe from environmental damage. It also provides secure conduit connections and a mounting thread. This specific configuration includes a 0.5-meter probe cable and a standoff adapter. The 21000 Proximity Probe Housing Assembly is an ideal choice for external mounting on rotating machinery. It supports predictive maintenance and machine protection strategies.

Ordering Configuration Details

The 21000-16-05-15-085-03-02 follows a systematic ordering code. The suffix "16" specifies the probe option as a 3300 XL 8 mm probe. The "05" indicates a probe cable length of 0.5 meters (20 inches). Next, the "15" designates a standoff adapter length of 1.5 inches (38 mm). The "085" represents the probe penetration dimension (Option D) of 8.5 inches. Finally, the "03" and "02" suffixes define the fittings and mounting thread options, respectively. This structured code ensures accurate specification of each assembly component.

Mechanical Specifications

The housing body is constructed from aluminum with a 304 stainless steel sleeve. This combination offers a good balance of weight and corrosion resistance. The mounting thread is 3/4-14 NPT, which is a standard size for many industrial applications. Moreover, the assembly includes a dome cover that screws into the housing body. Threaded ports are provided for conduit connections. The probe sleeve is available in an optional length to suit different installation needs. O-rings and a thread seal ensure a tight, leak-proof installation.

Fittings Included

This assembly comes with a comprehensive set of fittings. It includes one 3/4-14 NPT plug. Additionally, it provides one 3/4-14 to 1/2-14 NPT reducer. This reducer offers flexibility for connecting to different conduit sizes. Furthermore, the package includes a cable seal grip with multiple grommets. These grommets accommodate cable sizes of 1/8 to 3/16 inches, 1/4 to 5/16 inches, and 5/16 to 3/8 inches. This variety ensures a secure seal for various cable diameters. Consequently, the Bently Nevada 21000-16-05-15-085-03-02 is ready for installation with minimal additional parts.

Probe Penetration Considerations

The probe penetration length is the sum of Options C (standoff adapter) and D (probe penetration). For this model, the standoff adapter is 1.5 inches, and the probe penetration is 8.5 inches. The total visible probe length, however, may not show the probe P/N and S/N on a flag label for some combinations. For penetration lengths between 1.0 and 2.0 inches, counter-boring the machine case may be necessary. This reduces side view or rear view effects that could affect measurement accuracy. If the total penetration exceeds 300 mm (12 inches), additional sleeve support is required near the probe to prevent resonance. The adjustment range for Option D is 13 mm (± 0.5 in), allowing fine-tuning during installation.

Compliance and Certifications

The 21000 Proximity Probe Housing Assembly meets several important standards. It complies with Part 15 of the FCC Rules. It also adheres to the RoHS Directive 2011/65/EU. Furthermore, the assembly is certified for hazardous area applications. The Canadian Standards Association (CSA) provides explosion-proof ratings for North America. It is certified for Class 1 Divisions 1 and 2 Groups C and D. Additionally, it is rated for Class 2 Divisions 1 and 2 Groups E, F, and G. The circuit is non-incendive when connected per drawing 140979. The enclosure is Type 4 rated, ensuring protection against ingress of water and dust. Temperature classifications include T5 at Ta = -50°C to +40°C and T4 at Ta = -50°C to +80°C.

Installation Guidance

Installing the Bently Nevada 21000-16-05-15-085-03-02 requires careful attention to detail. First, select a suitable location on the machine casing. Ensure the area is clean and accessible. Next, prepare the mounting hole with the required 3/4-14 NPT thread. Thread the housing assembly into the prepared hole. Use the included thread seal to prevent leaks. Then, connect the conduit using the provided plug or reducer as needed. The cable seal grip should be fitted with the appropriate grommet for your cable size. After securing the assembly, adjust the probe penetration using the adjustment range of Option D. Finally, connect the probe cable to the extension cable using the Miniature ClickLoc connector. Proper installation is crucial for accurate and reliable vibration data.

Frequently Asked Questions (FAQ)

1. Is the Bently Nevada 21000-16-05-15-085-03-02 suitable for intrinsically safe applications?
Yes, the 21000 housing supports intrinsically safe applications when used with approved proximity probes and appropriate barriers. However, this specific model includes a standard probe. You should verify the complete system configuration for intrinsic safety compliance.

2. What does the "085" option represent in the model number?
The "085" specifies the probe penetration dimension (Option D) as 8.5 inches. This is the length the probe extends beyond the housing into the machine casing. It is adjustable within a range of 13 mm (± 0.5 in).

3. Can I use this housing assembly with a different probe length?
The housing is designed to accommodate the specific probe included in the assembly. Changing the probe length would alter the penetration and may require a different housing configuration. For custom requirements, please consult Bently Nevada.

4. What is the purpose of the standoff adapter (Option C)?
The standoff adapter provides additional spacing between the housing and the machine. This can help reduce side view effects. It also aids in positioning the probe tip at the optimal distance from the target surface. The 21000-16-05-15-085-03-02 includes a 1.5-inch standoff adapter.

5. How do I adjust the probe penetration after installation?
The probe penetration (Option D) has an adjustment range of 13 mm (± 0.5 in). This is achieved by rotating the probe within the housing. However, do not exceed the specified range to avoid damaging the probe or affecting measurement accuracy.
