Bently Nevada 21000-34-10-30-018-03-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-10-30-018-03-02 are listed below for quick reference:

Installation Guidance for Maximum Performance

When mounting this assembly, ensure the standoff adapter (3.0 in) and probe penetration (1.8 in) match your machine's clearance requirements. The 3/4-14 NPT mounting thread requires proper thread sealant to maintain explosion-proof integrity. Use the provided cable seal grip with appropriate grommet (for cable sizes 1/8 to 3/16, 1/4 to 5/16, or 5/16 to 3/8 inches) to prevent moisture ingress. Always verify the probe cable length (1.0 m) is sufficient to reach your monitor without strain.

Engineered for Hazardous Area Reliability

The 21000-34-10-30-018-03-02 is certified as CSA Type 4 enclosure and fully compliant with API 670 Standard for externally mounted proximity probe housings. The aluminum body with 304 stainless steel sleeve resists corrosion, while the included conduit fittings (3/4-14 NPT plug, reducer, and cable seal grip) simplify field wiring.

Maintenance and Reliability Tips

Periodically inspect the dome cover and conduit connections for signs of corrosion or loosening. The 0-rings inside the assembly should be replaced during any probe replacement to maintain the seal. Avoid overtightening fittings, as this can distort the housing threads. For long-term reliability, keep the probe tip and target surface clean per API 670 guidelines.

Robust Protection for Critical Vibration Monitoring

In rotating machinery monitoring, probe housing integrity directly impacts measurement reliability. The Bently Nevada 21000-34-10-30-018-03-02 Proximity Probe Housing Assembly provides a sealed, explosion-proof enclosure for 3300 XL 8 mm probes in harsh industrial environments. This assembly eliminates signal degradation from moisture, debris, and mechanical stress, ensuring accurate shaft vibration and position data.

Selection Guide and Purchasing Advice

When selecting a replacement housing, confirm your existing probe type and cable length. The 21000-34-10-30-018-03-02 is specifically configured for 3300 XL 8 mm probes with a 1.0 m cable. If your application requires different standoff or penetration, consult AutoDCSTech for alternative suffix options. All units are supplied new in factory packing with a 12-month warranty. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
