Installation & Setup
Proper installation is vital for optimal performance of the 21000-16-10-15-092-03-02. Follow these guidelines to ensure accurate measurements:
-
Mounting: Use the 3/4-14 NPT mounting thread for secure attachment to the machine casing. Ensure the mounting surface is clean and free of debris to prevent misalignment.
-
Probe insertion: Adjust the probe penetration (D dimension) to 9.2 in as specified. The probe should be positioned to achieve the correct gap voltage according to the monitoring system's requirements.
-
Cable routing: Route the probe cable through the provided cable seal grip, selecting the appropriate grommet size (1/8–3/16, 1/4–5/16, or 5/16–3/8 inches) for a tight seal.
-
Conduit connections: Use the included 3/4-14 NPT plug and reducer to connect conduit properly, maintaining the explosion-proof integrity.
-
Verification: After installation, verify that the probe is visible through the housing (if applicable) and that the cable is securely fastened.
For hazardous area installations, ensure that all connections follow the non-incendive circuit requirements per drawing 140979.
Maintenance & Reliability
The 21000-16-10-15-092-03-02 is designed for minimal maintenance, but periodic inspections are recommended to ensure long-term reliability:
