Industry Applications and Cost Impact
By enabling early detection of shaft vibration and position changes, the 21000-16-10-00-120-03-02 helps avoid catastrophic failures that can cost hundreds of thousands in lost production and repairs. Its CSA Type 4 and explosion-proof ratings allow installation in hazardous areas without additional protective enclosures, reducing overall system cost.
Installation and Setup Guidance
Mount the assembly using the 3/4-14 NPT mounting thread. The included fitting kit provides a 3/4-14 NPT plug, a reducer to 1/2-14 NPT, and a cable seal grip with grommets for cable diameters from 1/8 to 3/8 inches. Ensure the probe penetration of 12 inches is correctly set for your machine geometry. The aluminum body with 304 stainless steel sleeve offers corrosion resistance in harsh environments.
Maintenance and Reliability
Regularly inspect the housing for signs of corrosion or mechanical damage. Verify that the cable seal grip maintains a tight seal to prevent moisture ingress. The 21000 assembly is designed for long-term reliability, but periodic checks of the O-rings and thread seal are recommended. Always follow OEM guidelines for probe gap setting and calibration.
Selection Guide and Purchasing Advice
When selecting a proximity probe housing, consider the probe type, cable length, and mounting thread. The 21000-16-10-00-120-03-02 is configured with a 3300 XL 8 mm probe and 1.0 m cable, making it suitable for many standard installations.
