Bently Nevada 21000-16-10-15-256-03-02 Proximity Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21000-16-10-15-256-03-02 are listed below for quick reference:

Industry Applications

Turbine and Compressor Protection

In steam turbines and centrifugal compressors, shaft vibration must be monitored continuously. The 21000 housing, with its 3300 XL 8 mm probe and 1.0 m cable, provides precise proximity sensing. The CSA explosion-proof rating allows installation in Class 1 Division 1 areas where flammable gases may be present.

Pump and Motor Monitoring

For large pumps and electric motors, the 25.6 in probe penetration enables deep insertion into bearing housings. The aluminum body with 304 stainless steel sleeve resists corrosion in wet or chemical environments. This assembly meets API 670 standards for externally mounted proximity probe housings.

Installation & Setup Guidance

Mounting Considerations

Use the 3/4-14 NPT mounting thread to secure the housing to the machine case. For probe penetration lengths 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 probe penetration (C plus D) exceeds 300 mm (12 in), add sleeve support near the probe to prevent resonance.

Cable and Fitting Installation

The included fittings allow flexible conduit connections. The 3/4-14 NPT plug and reducer accommodate standard conduit sizes. The cable seal grip with grommets supports cable diameters from 1/8 to 3/8 inches. Ensure a proper seal to maintain the explosion-proof integrity of the enclosure.

Maintenance & Reliability

Inspection Intervals

Periodically inspect the housing for signs of corrosion or mechanical damage. Verify that all fittings remain tight and that the cable seal grip maintains a secure seal. The CSA Type 4 enclosure rating provides protection against water ingress, but regular visual checks are recommended.

Environmental Considerations

The housing is rated for ambient temperatures from -50 °C to +80 °C (T4 rating) or -50 °C to +40 °C (T5 rating). Ensure the operating environment stays within these limits to maintain safety certifications. Avoid exposing the assembly to excessive vibration beyond its design specifications.

Engineered for Reliable Vibration Monitoring

In rotating machinery, accurate vibration measurement is critical to prevent catastrophic failures. The Bently Nevada 21000-16-10-15-256-03-02 proximity probe housing assembly provides a robust, sealed enclosure for proximity probes in harsh industrial settings. This component is essential for continuous machine health monitoring, helping operators avoid unplanned downtime and extend equipment life.

Compatibility & Integration

This proximity probe housing assembly is designed for use with Bently Nevada 3300 XL 8 mm proximity probes. The 21000 series is fully compliant with API 670 standards, ensuring compatibility with most industrial vibration monitoring systems. The CSA hazardous area approvals make it suitable for global installations requiring explosion-proof equipment.
