Bently Nevada 21000-28-00-20-065-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-28-00-20-065-04-02 are listed below for quick reference:

Industry Applications for Reliable Vibration Monitoring

The 3300 XL 8 mm probe inside provides accurate proximity measurements for shaft vibration and thrust position monitoring. By selecting the 21000-28-00-20-065-04-02, engineers ensure compliance with API 670 standards, reducing the risk of false trips and unplanned downtime.

Installation and Setup Guidance

When installing the 21000-28-00-20-065-04-02, consider the probe penetration length (Option C + D). For penetrations between 1.0 and 2.0 inches, counter boring the machine case may be necessary to reduce side view or rear view effects. If the total penetration exceeds 300 mm (12 in), add sleeve support near the probe to prevent resonance. The adjustment range of probe penetration option D is 13 mm (± 0.5 in). Ensure the 3/4-14 NPT mounting thread is properly sealed to maintain the explosion-proof rating.

Maintenance and Reliability

Periodically inspect the housing for corrosion or damage, especially in harsh environments. The aluminum body with 304 stainless steel sleeve offers good corrosion resistance, but regular visual checks are recommended. Verify that all O-rings and thread seals remain intact to preserve the CSA Type 4 enclosure integrity. Clean the exterior with a non-abrasive cloth; avoid disassembling the housing unless necessary.

Robust Protection for Critical Rotating Machinery

When monitoring vibration and position on turbines, compressors, and pumps, the probe housing is as vital as the probe itself. The Bently Nevada 21000-28-00-20-065-04-02 Proximity Probe Housing Assembly provides a rugged, explosion-proof enclosure for the 3300 XL 8mm proximity probe, ensuring reliable data collection in hazardous environments. This assembly is engineered to meet API 670 standards for externally mounted housings, offering a secure solution for continuous machinery protection.

Compatibility and Integration

The 21000 series housing is designed to work with Bently Nevada 3300 XL 8 mm proximity probes. The housing includes threaded ports for conduit connections, making field wiring straightforward. Always use approved hazardous area probe configurations for intrinsically safe applications.

Selection Guide and Purchasing Advice

When ordering the 21000-28-00-20-065-04-02, confirm that the standoff adapter length (2 inches) and probe penetration (6.5 inches) match your machine geometry. If you need a different configuration, refer to the suffix code structure: 21000 - AA-BB-CC-DDD-EE-FF. AutoDCSTech stocks this assembly new and original in factory packing with a 12-month warranty.
