Applications
The Bently Nevada 21000-00-00-15-050-00-02 is ideal for use in the oil & gas, power generation, and heavy manufacturing industries. It is designed to house proximity probes that monitor shaft vibration and position in turbines, compressors, pumps, and motors. The housing's explosion-proof rating makes it suitable for hazardous areas where flammable gases or dust may be present. Its compliance with API 670 ensures it meets the stringent requirements of the petroleum industry.
Installation & Setup
When installing the 21000-00-00-15-050-00-02, ensure the mounting thread (3/4-14 NPT) is properly sealed to maintain the enclosure's integrity. The standoff adapter (minimum length 1.5 inches) must be used to position the probe correctly. Since the probe and cable are not included (suffix 00), you will need to order them separately. Follow the manufacturer's guidelines for torquing and alignment to achieve accurate measurements.
Maintenance & Reliability
Regular inspection of the housing is recommended to ensure the O-rings and thread seals remain in good condition. The aluminum body with stainless steel sleeve resists corrosion, but periodic cleaning and checking for any damage will extend the service life. The housing's robust construction minimizes downtime, making it a cost-effective choice for critical machinery monitoring.
Selection Guide
Before ordering, verify that the probe penetration (5 inches) and standoff adapter length (1.5 inches) match your application requirements. The mounting thread option 02 (3/4-14 NPT) is mandatory when the standoff adapter is not 00. For hazardous area installations, confirm that the housing's CSA certifications align with your site's classification.
