Applications
The Bently Nevada 21000-28-10-00-180-00-02 is ideal for vibration monitoring in critical rotating equipment such as turbines, compressors, pumps, and motors. Its explosion-proof certification makes it suitable for hazardous environments in oil and gas, chemical, and petrochemical plants. The 18-inch probe penetration allows installation in deeper machine casings, ensuring accurate measurement of shaft vibration and position.
This housing assembly is also a smart replacement for older probe housings, offering improved compliance with API 670 and CSA Type 4 enclosure ratings. Its robust construction minimizes maintenance needs, contributing to reduced downtime and lower total cost of ownership.
Installation and Setup
When installing the Bently Nevada 21000-28-10-00-180-00-02, ensure the mounting thread (3/4-14 NPT) is properly sealed to prevent leakage. The probe sleeve length should be chosen to match the required penetration depth. Verify that the cable length (1.0 m) reaches the junction box without strain. For hazardous area installations, follow the wiring drawing 140979 to maintain non-incendive circuit integrity.
Maintenance and Reliability
The 21000 series housing is designed for long service life with minimal maintenance. Regularly inspect the O-rings and thread seal for wear to maintain explosion-proof integrity. Periodically verify the probe's visible P/N and S/N for traceability. The aluminum body with stainless steel sleeve resists corrosion, but in extreme environments, occasional cleaning is recommended.
Selection Guide
Before ordering, confirm that the probe cable length (1.0 m) and penetration (18 in) match your machine's requirements. Verify the mounting thread option (3/4-14 NPT) fits your installation. If you need fittings or a standoff adapter, select the appropriate suffix codes. For North American end users, CA versions are available; for other regions, use the standard 21000 housing.
