Introduction to the 21000-16-05-00-096-00-02

When reliable vibration monitoring is critical for rotating machinery, the 21000-16-05-00-096-00-02 from Bently Nevada provides a robust solution. This proximity probe housing assembly is designed for hazardous area use, featuring an aluminum body with a 304 stainless steel sleeve. It supports a 3300 XL 8 mm probe and offers a 0.5 m probe cable length, making it suitable for tight installations.

Key Features and Technical Specs

• Probe Option: 3300 XL 8 mm probe with connector
• Probe Cable Length: 0.5 m (20 in)
• Probe Penetration: 9.6 in
• Mounting Thread: 3/4-14 NPT
• Material: Aluminum body with 304 stainless steel sleeve
• Weight: 1.1 kg (2.4 lb) typical, without fittings
• Maximum (C) + (D) Dimension: 13.5 in (34.3 mm)
• Approvals: CSA explosion proof for hazardous areas; CSA Type 4 enclosure; compliant with API 670 Standard

The 8 mm probe size is ideal for close-quarters monitoring, while the 0.5 m cable reduces signal loss in short runs. The 3/4-14 NPT thread ensures secure mounting in standard conduit openings.

Applications and Use Cases

Engineers in oil and gas, power generation, and petrochemical industries rely on the 21000-16-05-00-096-00-02 for shaft vibration and position monitoring. Its CSA explosion-proof rating makes it suitable for Class I, Division 1 hazardous locations. Additionally, the housing meets API 670 standards, ensuring compatibility with industry-standard externally mounted probe setups.

Installation and Setup

Mount the housing using the 3/4-14 NPT thread into a conduit opening. Ensure the probe sleeve length matches the required penetration depth of 9.6 in. The assembly includes a dome cover, O-rings, and a thread seal for a weathertight fit. For hazardous areas, follow local electrical codes and use approved conduit fittings.

Maintenance and Reliability

Regularly inspect the O-rings and thread seal for wear, especially in corrosive environments. The stainless steel sleeve resists rust, while the aluminum body provides lightweight durability. Periodic cleaning of the probe face ensures accurate readings. For long-term reliability, verify that the mounting thread remains tight to prevent vibration-induced loosening.

Compatibility and Integration

The 21000-16-05-00-096-00-02 integrates with Bently Nevada monitoring systems using 3300 XL 8 mm probes. It works with standard conduit systems and can be paired with optional standoff adapters (not included). The CSA Type 4 rating allows outdoor installation in wet environments.

Troubleshooting and Common Issues

If signal loss occurs, check the probe cable connection and ensure the 0.5 m cable is not damaged. For mounting issues, verify the 3/4-14 NPT thread is clean and properly aligned. If the probe tip is not visible, confirm the penetration depth is set to 9.6 in. Always refer to the Bently Nevada manual for detailed diagnostics.
