21000-28-10-00-180-00-02 | Bently Nevada 8 mm Probe Housing Assembly

Introduction to the Bently Nevada 21000-28-10-00-180-00-02

When machinery reliability is critical, the 21000-28-10-00-180-00-02 from Bently Nevada provides a robust solution for proximity probe housing. This assembly is designed for hazardous area applications and meets API 670 standards. It includes a 3300 XL 8 mm probe with a 1.0 m cable and a 3/4-14 NPT mounting thread. The aluminum body with a 304 stainless steel sleeve ensures durability in demanding environments.

Key Features and Technical Specifications

• Probe option: 3300 XL 8 mm probe with selectable hazardous area approvals.
• Probe cable length: 1.0 m (39 in) for flexible installation.
• Mounting thread: 3/4-14 NPT for secure attachment.
• Probe penetration: 18 in (180) for deep measurement.
• Material: Aluminum body with 304 stainless steel sleeve for corrosion resistance.
• Weight: 1.1 kg (2.4 lb) typical, without fittings.
• Certified as CSA Type 4 enclosure for explosion-proof hazardous areas.

A distinctive spec is the 18 in probe penetration, which allows installation in thicker machine casings without sacrificing signal accuracy. This feature reduces the need for custom adapters, saving both time and cost.

Applications and Use Cases

Industries such as oil and gas, power generation, and petrochemical processing rely on the 21000-28-10-00-180-00-02 for critical asset monitoring. It is ideal for measuring shaft vibration and position in compressors, turbines, and pumps. Because it is CSA certified for Class I Divisions 1 and 2 Groups C and D, it operates safely in explosive atmospheres. This reduces downtime risks and maintenance costs over the long term.

Installation and Setup

Mount the housing using the 3/4-14 NPT thread directly into a machine port. Ensure the probe penetration of 18 in is correctly set for optimal clearance. Connect the 1.0 m cable to a compatible monitor, following the wiring diagram provided by Bently Nevada. For hazardous area installations, use the supplied thread seal and O-rings to maintain the explosion-proof rating.

Maintenance and Reliability

Inspect the O-rings and thread seal periodically for wear. The aluminum and stainless steel construction resists corrosion, extending service life. Regular checks of the probe cable for damage help prevent signal loss. This routine care minimizes unplanned repairs and supports long-term cost efficiency.

Compatibility and Integration

The 21000-28-10-00-180-00-02 works with Bently Nevada monitoring systems that accept 3300 XL 8 mm probes. It is fully compliant with API 670 standards for externally mounted housings. For intrinsically safe applications, order hazardous area approved probes with the housing. The CSA certification ensures compatibility with North American safety requirements.
