Installation Guide for the Bently Nevada 21000-16-10-15-092-03-02

Mount the housing using the 3/4-14 NPT thread into a compatible port. Ensure the probe penetration (9.2 in) matches the required depth for your machine. Connect the cable using the supplied seal grip and grommets, selecting the appropriate size for your cable diameter (1/8 to 3/8 inches). For hazardous area installations, follow the wiring diagram 140979 to maintain non-incendive circuit compliance. Always verify the standoff adapter length (1.5 in) before final tightening to avoid probe damage.

Maintenance and Reliability of the 21000-16-10-15-092-03-02

Regularly inspect the O-rings and thread seal for wear to maintain explosion-proof integrity. The aluminum body with stainless steel sleeve resists corrosion, extending service life and reducing replacement frequency. Check cable grommets annually for cracks or hardening, especially in high-temperature environments up to +80 °C. By following these simple steps, you maximize uptime and minimize maintenance costs over the product's lifespan.
