Bently Nevada 21000-34-05-20-018-04-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-34-05-20-018-04-02 are listed below for quick reference:

Industry Applications and Failure Prevention

This housing assembly is designed for externally mounted proximity probes on critical rotating equipment such as turbines, compressors, and pumps. The API 670 compliant design ensures proper probe positioning and protection from contaminants. By using a sealed housing with a connector protector, the risk of signal degradation from moisture or debris is minimized. The 0.5 m probe cable length suits tight installations where the monitor is close to the machine.

Installation and Setup Guidance

Install the housing using the 3/4-14 NPT mounting thread. Ensure the standoff adapter (2.0 in) is correctly set to achieve the desired probe gap. The probe penetration of 1.8 in must be verified during installation to avoid contact with rotating parts. Use the provided 3/4-14 NPT plug for unused conduit ports to maintain enclosure integrity. For hazardous area approvals, order with the appropriate E:00, E:01, E:02, or E:04 options to achieve CSA explosion-proof rating.

Maintenance and Reliability

Periodically inspect the housing for signs of corrosion or damage, especially in harsh environments. Check that the dome cover is securely tightened and O-rings are intact. The 304 stainless steel sleeve resists wear, but verify probe tip condition during routine shutdowns. No internal disassembly is required for standard maintenance.

Robust Protection for Critical Vibration Monitoring

In rotating machinery monitoring, the probe housing is the first line of defense. The Bently Nevada 21000-34-05-20-018-04-02 Proximity Probe Housing Assembly provides a rugged, sealed enclosure for the 3300 XL 8 mm probe, ensuring reliable operation in harsh industrial environments. This assembly combines an aluminum body with a 304 stainless steel sleeve, offering corrosion resistance and mechanical strength.

Compatibility and Integration

This assembly is designed for use with Bently Nevada 3300 XL 8 mm proximity probes. The connector protector ensures compatibility with standard extension cables. The housing is CSA Type 4 rated, making it suitable for outdoor and washdown areas. Always verify that the probe option and cable length match your system requirements.
