Applications and Use Cases

Engineers rely on the 21000-16-10-15-029-03-02 for vibration monitoring in turbines, compressors, and pumps. Its CSA explosion-proof certification makes it suitable for hazardous areas classified as Class 1 Divisions 1 and 2 Groups C and D. The housing is fully compliant with API 670 standards for externally mounted proximity probes, ensuring consistent performance in critical rotating machinery.

Installation and Setup

During installation, ensure the probe penetration length (C plus D) does not exceed 300 mm (12 in) without sleeve support to prevent resonance. For probe penetration lengths between 1.0 and 2.0 inches, counter boring the machine case may reduce side view effects. The adjustment range of probe penetration option D is 13 mm (± 0.5 in). Use the included fittings to secure conduit connections and seal the cable entry properly.

Maintenance and Reliability

Regular inspection of the housing and probe cable is recommended to maintain measurement accuracy. The aluminum body with 304 stainless steel sleeve provides long-term durability in harsh environments. Verify that the 0-rings and thread seal remain intact to preserve the explosion-proof rating. For best results, follow the manufacturer's guidelines for periodic checks.

Compatibility and Integration

The 21000-16-10-15-029-03-02 integrates with Bently Nevada monitoring systems that accept 8 mm proximity probes. It is compatible with CSA Type 4 enclosures and supports intrinsically safe applications when paired with approved proximity probes. The housing can be ordered with hazardous area approvals for use in North American Class I Division 1 and 2 locations.
