Bently Nevada 21000-16-10-15-070-03-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-16-10-15-070-03-02 are listed below for quick reference:

Industry Applications and Failure Mode Prevention

The 3300 XL 8 mm probe provides high-resolution displacement measurements. In applications where probe penetration exceeds 300 mm (12 in), sleeve support is required to prevent resonance. For probe penetration lengths between 1.0 and 2.0 inches, counter boring the machine case may be necessary to reduce side or rear view effects. By using this assembly, you reduce the risk of undetected shaft vibration that can lead to bearing failure or unplanned downtime.

Installation and Setup Guidance

When installing the 21000-16-10-15-070-03-02, ensure the mounting thread (3/4-14 NPT) is properly sealed to maintain the explosion-proof rating. The standoff adapter (1.5 in) positions the probe at the correct distance from the shaft. The probe penetration (7 in) combined with the cable length (1.0 m) determines the overall reach. For optimal performance, verify that the probe tip is within the specified gap range. Use the provided cable seal grip with appropriate grommet size (1/8 to 3/16 inches, 1/4 to 5/16 inches, or 5/16 to 3/8 inches) to secure the cable entry.

Maintenance and Reliability

Periodically inspect the housing for signs of corrosion or damage, especially in harsh environments. The aluminum body with 304 stainless steel sleeve offers corrosion resistance. Check the O-rings and thread seal during routine maintenance to ensure the enclosure integrity. The assembly is rated CSA Type 4 and explosion-proof for hazardous areas (Class 1 Divisions 1 and 2 Groups C and D, Class 2 Divisions 1 and 2 Groups E, F and G, Class III). Always follow site safety procedures when working in classified areas.

Robust Protection for Critical Vibration Monitoring

Industrial rotating machinery demands precise and reliable vibration monitoring to prevent catastrophic failures. The Bently Nevada 21000-16-10-15-070-03-02 Proximity Probe Housing Assembly provides a rugged, explosion-proof enclosure for proximity probes in hazardous environments. This assembly is engineered to meet API 670 standards, ensuring consistent performance in the most demanding applications.

Compatibility and Integration

The 21000 housing is designed for use with Bently Nevada proximity probes and monitoring systems. It is fully compliant with API 670 for externally mounted proximity probe housings. The assembly supports both 21000 aluminum and 24701 stainless steel housings for intrinsically safe applications. The CSA certification ensures safe operation in North American hazardous locations.

Selection Guide and Purchasing Advice

When selecting a proximity probe housing assembly, consider the probe type, cable length, standoff adapter, penetration depth, and fittings. The 21000-16-10-15-070-03-02 combines a 3300 XL 8 mm probe with a 1.0 m cable, 1.5 in standoff adapter, and 7 in penetration, making it suitable for many standard machine train configurations.
