Bently Nevada 21000-34-10-20-050-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-10-20-050-04-02 are listed below for quick reference:

Real-World Applications in Rotating Machinery

The 2.0 in standoff adapter and 5.0 in probe penetration allow flexible mounting in tight spaces while maintaining the correct gap for accurate eddy-current measurements. The CSA Type 4 enclosure rating ensures operation in wet or dusty environments, reducing false trips and maintenance interventions.

Installation and Setup Guidance

When installing the 21000-34-10-20-050-04-02, ensure the mounting thread (3/4-14 NPT) matches the machine port. The probe cable length of 1.0 m (39 in) limits the distance to the extension cable junction. Use the supplied 3/4-14 NPT plug for unused conduit entries to maintain the explosion-proof seal. Verify that the probe tip extends through the sleeve by the correct amount per the manufacturer's gap setting procedure.

Maintenance and Reliability

Periodically inspect the housing for signs of corrosion, especially on the aluminum body if exposed to caustic chemicals. Check the O-rings and thread seal integrity during each turnaround to prevent moisture ingress. The 304 stainless steel sleeve resists wear from probe insertion and removal. No internal adjustments are required; the assembly is designed for long-term, maintenance-free operation.

Robust Protection for Critical Vibration Monitoring

Industrial rotating machinery demands precise vibration monitoring to prevent catastrophic failures. The Bently Nevada 21000-34-10-20-050-04-02 proximity probe housing assembly provides a rugged, sealed enclosure for 3300 XL 8 mm probes in harsh environments. This assembly ensures reliable, accurate measurements while protecting the sensor from contaminants, moisture, and mechanical damage.

Compatibility and Integration

The 21000-34-10-20-050-04-02 is designed for use with Bently Nevada 3300 XL 8 mm proximity probes. It is fully compliant with the American Petroleum Institute's API 670 Standard for externally mounted proximity probe housings. The CSA Type 4 enclosure rating and explosion-proof certification (with appropriate options) allow integration into hazardous area installations without additional enclosure modifications.

Selection Guide and Purchasing Advice

When selecting a proximity probe housing, verify that the probe option, cable length, standoff adapter, and penetration match your machine's geometry and access constraints. The 21000-34-10-20-050-04-02 is a standard configuration for many turbomachinery applications. AutoDCSTech stocks this assembly as new and original in factory packing with a 12-month warranty.
