Industry Applications
The 21000-16-10-00-072-03-02 is ideal for machinery protection in rotating equipment such as turbines, compressors, and pumps. In a typical scenario, this housing protects the proximity probe while maintaining precise gap settings, enabling accurate shaft vibration and axial position monitoring. The explosion-proof rating makes it suitable for hazardous areas in oil refineries, chemical plants, and gas processing facilities.
Installation & Setup Guidance
When installing the 21000-16-10-00-072-03-02, ensure the mounting thread (3/4-14 NPT) is properly sealed and torqued to prevent leakage. The cable seal grip must accommodate the probe cable diameter; use the appropriate grommet from the provided set. Position the housing so that the probe tip reaches the target surface with the correct penetration depth (7.2 in). Verify that the probe cable length (1.0 m) is sufficient for routing to the monitor. For hazardous areas, follow all applicable local codes and use conduit connections as required.
Maintenance & Reliability
Regularly inspect the housing for signs of corrosion, especially at threaded joints and seals. Check the O-rings and thread seal for wear and replace them if damaged. Ensure the cable seal grip remains tight to maintain the environmental seal. Because the 21000-16-10-00-072-03-02 is built to API 670 standards, it offers long service life, reducing downtime and maintenance costs—a key consideration for budget-conscious operations.
Selection Guide & Purchasing Advice
Before ordering, verify that the 21000-16-10-00-072-03-02 matches your probe type (3300 XL 8 mm) and cable length requirements. Confirm the mounting thread and fitting options suit your installation.
