Applications
The 21000-16-10-15-102-03-02 is ideal for vibration monitoring on rotating machinery such as turbines, compressors, pumps, and motors. In petrochemical plants, refineries, and power generation facilities, this housing assembly provides reliable probe mounting in potentially explosive atmospheres. Its compliance with API 670 ensures it meets the stringent requirements of the oil and gas industry, making it a preferred choice for critical asset protection.
For example, in a refinery, the 21000-16-10-15-102-03-02 can be used to mount a 3300 XL 8 mm proximity probe to monitor shaft vibration in a large centrifugal compressor. The 1.5-inch standoff adapter and 10.2-inch probe penetration allow for precise positioning within the bearing housing, while the 3/4-14 NPT mounting thread ensures a secure, leak-proof fit.
Installation & Setup Guidance
Proper installation is critical for accurate vibration measurement. Begin by verifying that the mounting thread (3/4-14 NPT) matches the machine's tapping. Apply a suitable thread sealant to prevent leakage. When inserting the probe, ensure the probe tip is positioned according to the manufacturer's recommended gap (typically specified in the probe datasheet). Use the cable seal grip to secure the probe cable, ensuring that the grommet size matches the cable diameter to maintain the explosion-proof seal. Tighten all fittings to the recommended torque to avoid damaging the housing or the probe.
Maintenance & Reliability
Regular inspection of the housing assembly ensures long-term reliability. Periodically check for signs of corrosion, especially on the aluminum body, and verify that all fittings remain tight. The stainless steel sleeve resists wear, but inspect the probe tip for damage or buildup. In harsh environments, clean the exterior with a non-abrasive cleaner. Because the 21000-16-10-15-102-03-02 is designed for hazardous areas, always follow site-specific safety procedures when performing maintenance. Proper care extends the service life and reduces unplanned downtime, contributing to lower overall maintenance costs.
Selection Guide & Purchasing Advice
Before ordering the 21000-16-10-15-102-03-02, verify that the probe cable length (1.0 m) and standoff adapter (1.5 in) meet your application requirements. Confirm that the mounting thread (3/4-14 NPT) matches your machine's connection. If you need different cable lengths or adapters, consider other suffix codes in the 21000 series. Ensure the probe is compatible with your monitoring system.
