Technical Specifications Breakdown

Key parameters for the 21000-34-10-15-028-04-02 are listed below for quick reference:

Industry Applications

The 1.5 in standoff adapter and 2.8 in probe penetration allow precise positioning for radial vibration measurement. In steam turbines, the 21000-34-10-15-028-04-02 provides a stable, explosion-proof enclosure that meets CSA Type 4 requirements, reducing the risk of false trips due to environmental contamination.

Installation & Setup Guidance

When installing the 21000-34-10-15-028-04-02, ensure the mounting thread (-02 = 3/4-14 NPT) matches the machine case port. The 1.0 m probe cable should be routed without sharp bends to avoid signal degradation. Verify the standoff adapter (1.5 in) provides the correct gap for the 3300 XL 8 mm probe. Use the included 3/4-14 NPT plug for unused conduit ports to maintain enclosure integrity.

Maintenance & Reliability

Inspect the O-rings and dome cover seal periodically to maintain the CSA Type 4 rating. The aluminum body with 304 stainless steel sleeve resists corrosion in typical industrial environments. For hazardous area installations, confirm the probe option (34) with selectable approvals matches the area classification. Replace the assembly if the probe sleeve shows wear or damage.

Robust Vibration Monitoring for Critical Rotating Machinery

In the demanding world of turbomachinery protection, a reliable proximity probe housing is essential for accurate shaft vibration and position measurements. The Bently Nevada 21000-34-10-15-028-04-02 Proximity Probe Housing Assembly provides a rugged, certified enclosure for the 3300 XL 8 mm probe, ensuring consistent performance in hazardous environments. This assembly is designed to meet API 670 standards, making it a trusted choice for compressors, turbines, and pumps.

Selection Guide & Purchasing Advice

When selecting a replacement or new assembly, verify the suffix codes match your application: probe option, cable length, standoff, penetration, fitting, and mounting thread.
