21000-34-10-30-065-03-02 | Bently Nevada 1.0 m Probe Housing Assembly

Introduction to the 21000-34-10-30-065-03-02

When industrial environments demand precise vibration monitoring, the 21000-34-10-30-065-03-02 from Bently Nevada provides a robust solution. This proximity probe housing assembly is engineered for hazardous areas, featuring CSA Type 4 enclosure certification and API 670 compliance. With a 1.0 m probe cable and selectable hazardous area approvals, it meets rigorous safety standards while ensuring reliable data collection.

The 21000 series has evolved to address the growing need for durable, externally mounted probes in rotating machinery applications. The 21000-34-10-30-065-03-02 combines an aluminum body with a 304 stainless steel sleeve, offering corrosion resistance and mechanical strength. Its design includes a dome cover, threaded conduit ports, and an optional standoff adapter, making it adaptable to various installation scenarios.

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: 3.0 in
• Probe Penetration: 6.5 in
• Mounting Thread: 3/4-14 NPT
• Material: Aluminum body with 304 stainless steel sleeve
• Maximum (C) + (D) Dimension: 32.9 in (83.5 cm)
• Weight: 1.1 kg (2.4 lb) typical, without fittings

One distinctive spec is the 3.0 in standoff adapter, which allows precise positioning of the probe relative to the shaft. This feature reduces installation errors and improves measurement accuracy in tight spaces.

Applications and Use Cases

Engineers commonly deploy the 21000-34-10-30-065-03-02 in turbine, compressor, and pump monitoring systems. Its explosion-proof rating makes it suitable for oil and gas facilities, chemical plants, and refineries. The assembly supports both radial and axial vibration measurements, helping operators detect early signs of bearing wear or imbalance. Because it complies with API 670, it integrates seamlessly into existing protection systems.

Installation and Setup

Mounting the 21000-34-10-30-065-03-02 requires a 3/4-14 NPT threaded port. The kit includes one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and a cable seal grip with grommets for cable sizes from 1/8 to 3/8 inches. Ensure the probe sleeve penetrates 6.5 in into the housing. Use the standoff adapter to set the gap correctly. Always follow the manufacturer's manual for torque specifications and wiring.

Maintenance and Reliability

Routine inspection of the 21000-34-10-30-065-03-02 extends its service life. Check the O-rings and thread seal for wear every six months. Verify the cable grip remains tight to prevent moisture ingress. The aluminum and stainless steel construction resists corrosion in harsh environments, reducing replacement costs over time. For hazardous area installations, follow all local safety regulations during maintenance.

Compatibility and Integration

The 21000-34-10-30-065-03-02 works with Bently Nevada 3300 XL 8 mm proximity probes and compatible monitoring systems. It supports both standard and intrinsically safe applications. The CSA Type 4 enclosure ensures dust and water resistance, making it suitable for outdoor or washdown areas. For system integration, refer to the API 670 standard for externally mounted probe housings.
