21000-34-10-20-095-03-02 | Bently Nevada 8 mm Probe Housing Assembly

Introduction to the 21000-34-10-20-095-03-02

When industrial machinery demands precise vibration monitoring, the 21000-34-10-20-095-03-02 from Bently Nevada provides a robust solution. This proximity probe housing assembly is part of the 21000 series, engineered for hazardous area applications. It combines an aluminum body with a 304 stainless steel sleeve for durability. The assembly includes a 3300 XL 8 mm probe with connector protector, selectable hazardous area approvals, and a 1.0 m probe cable. This model supports reliable data collection in demanding environments.

Key Features and Technical Specifications

• Probe Option: 3300 XL 8 mm probe with connector protector and selectable hazardous area approvals.
• Probe Cable Length: 1.0 m (39 in).
• Standoff Adapter: 2.0 in.
• Probe Penetration: 9.5 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: 32.9 in (83.5 cm).

The unique spec here is the 9.5 in probe penetration, which allows deep insertion into machinery for accurate vibration readings. This feature reduces signal loss and improves monitoring reliability.

Applications and Use Cases

In the oil and gas industry, the 21000-34-10-20-095-03-02 excels at monitoring rotating equipment like pumps and compressors. Its CSA Type 4 enclosure and explosion-proof rating make it suitable for hazardous areas. Additionally, the assembly complies with API 670 standards, ensuring compatibility with external proximity probe installations. This model is ideal for predictive maintenance programs that require consistent data from harsh environments.

Installation and Setup

Mount the assembly using the 3/4-14 NPT thread option. The standoff adapter length of 2.0 in simplifies positioning. Included conduit 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 various cable sizes—streamline wiring. Ensure the probe sleeve is correctly inserted to achieve the 9.5 in penetration depth. Always follow Bently Nevada's installation manual for torque specifications.

Maintenance and Reliability

Regularly inspect the O-rings and thread seal for wear. The aluminum body and stainless steel sleeve resist corrosion in humid or corrosive environments. Periodic checks of the cable seal grip grommets maintain ingress protection. This assembly's robust construction minimizes downtime, offering long-term value in continuous operation settings.

Compatibility and Integration

The 21000-34-10-20-095-03-02 integrates with Bently Nevada monitoring systems and third-party data acquisition units. Its 8 mm probe output is compatible with standard vibration analyzers. For hazardous area use, pair it with intrinsically safe barriers as needed. The assembly's CSA approval ensures compliance with North American safety standards.
