21000-16-10-15-081-03-02 | Bently Nevada 1.0 m Cable Proximity Probe Housing Assembly

Introduction to the Bently Nevada 21000-16-10-15-081-03-02 Proximity Probe Housing Assembly

When machine vibration threatens uptime, the 21000-16-10-15-081-03-02 from Bently Nevada provides a robust solution. This Proximity Probe Housing Assembly is engineered for hazardous area applications, featuring CSA explosion-proof certification and compliance with API 670 standards. With a 1.0 m probe cable and 8 mm 3300 XL probe, it delivers accurate proximity measurements for critical rotating machinery.

Key Features and Technical Specifications

The 21000-16-10-15-081-03-02 combines precision with durability. Below are its core specifications:

• Probe Option: 3300 XL 8 mm probe with connector
• Probe Cable Length: 1.0 m (39 in)
• Standoff Adapter: 1.5 in (38 mm)
• Probe Penetration (D): 8.1 in (081)
• Mounting Thread: 3/4-14 NPT
• Fittings: One 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets for multiple cable sizes
• Material: Aluminum body with 304 stainless steel sleeve
• Weight: 1.1 kg (2.4 lb) typical, without fittings
• Maximum (C)+(D) with visible probe P/N and S/N: 17.0 in (43.18 cm)
• Maximum (C)+(D) Dimension: 32.9 in (83.5 cm)

One distinctive spec is the 8.1 in probe penetration, which allows precise installation in deep bearing housings. This reduces side-view effects and improves measurement accuracy.

Real-World Applications and Use Cases

In the oil and gas industry, the 21000-16-10-15-081-03-02 excels at monitoring compressor and turbine vibrations. For example, a refinery using this housing assembly can detect early shaft displacement, preventing catastrophic failures. Similarly, power generation plants benefit from its CSA Type 4 enclosure rating, which withstands harsh environments. Consequently, maintenance teams gain reliable data for predictive maintenance programs.

Installation Guide and Setup Tips

When installing the 21000-16-10-15-081-03-02, ensure the mounting thread (3/4-14 NPT) aligns with the machine case. For probe penetration lengths between 1.0 and 2.0 inches, counter boring may be necessary to reduce side-view effects. Moreover, if the combined (C)+(D) dimension exceeds 300 mm (12 in), add sleeve support near the probe to prevent resonance. The adjustment range for probe penetration option D is 13 mm (±0.5 in), providing flexibility during setup.

Maintenance and Reliability Tips

Regular inspection of the 21000-16-10-15-081-03-02 ensures long service life. Check the O-rings and thread seal periodically for wear, especially in high-temperature environments (up to 80 °C for T4 rating). Additionally, verify that the cable seal grip grommets remain intact to maintain the explosion-proof seal. By following these steps, you reduce downtime and extend the housing assembly's operational life.

Compatibility and Integration

The 21000-16-10-15-081-03-02 integrates seamlessly with Bently Nevada monitoring systems. It is fully compliant with API 670 for externally mounted proximity probe housings. Furthermore, the CSA certification for Class 1 Divisions 1 and 2 Groups C and D ensures safe operation in hazardous areas. For intrinsically safe applications, pair it with approved proximity probes and Bently Nevada rack-based monitors.
