Key Features and Technical Specifications

The 24701-28-05-00-070-04-01 is engineered for durability and precision. Its 303 stainless steel body, complemented by a 304 stainless steel sleeve, offers excellent corrosion resistance in demanding industrial environments. The housing assembly includes a dome cover, threaded ports for conduit connections, a probe sleeve, O-rings, a reverse mount proximity probe, and a thread seal. Optional conduit fittings and a standoff adapter are available to suit specific installation needs.

• Probe option: 3300 XL 8mm with approval option
• Probe cable length: 0.5 m (20 in)
• Probe penetration: 0.7 in
• Fittings option: One 3/4-14 NPT plug only
• Mounting thread option: As cast without threads
• Weight: 1.8 kg (4.1 lb) typical, without fittings
• Maximum (C) + (D) dimension: 13.5 in (34.3 mm)

The 8mm probe size is a distinctive feature, making it suitable for applications where space is limited yet accuracy is paramount. This compact form factor allows for installation in tighter locations without compromising measurement integrity.

Applications and Use Cases

This housing assembly is ideal for use in turbines, compressors, pumps, and other rotating equipment where shaft vibration and position monitoring are critical. In petrochemical plants, the stainless steel construction withstands harsh chemicals and moisture. For power generation facilities, the reliable enclosure helps maintain continuous operation. Moreover, the 0.5 m cable length is well-suited for installations where the monitor is close to the machine, reducing signal loss. Consequently, this product supports predictive maintenance strategies that minimize unplanned downtime.

Installation and Setup Guidance

Proper installation is essential for accurate readings. Begin by verifying the mounting thread option—this unit is supplied as cast without threads, so you may need to prepare the mounting surface accordingly. The probe penetration of 0.7 in must be set precisely to achieve the correct gap. Use the included 3/4-14 NPT plug for conduit connections, ensuring a secure and moisture-resistant seal. Always follow the manufacturer's manual for torque specifications and alignment procedures. Additionally, check that the probe cable length of 0.5 m is sufficient for your routing path without sharp bends.

Maintenance and Reliability

Routine inspection of the housing assembly is straightforward. Periodically check the O-rings and thread seal for signs of wear or degradation. Verify that the dome cover is tightened properly to prevent ingress of contaminants. Since the housing is made of stainless steel, it resists corrosion, but regular cleaning with a mild detergent and water is recommended to maintain surface integrity. By adhering to these simple practices, you extend the service life of the assembly and ensure consistent monitoring performance.

Compatibility and Integration

The 24701-28-05-00-070-04-01 is part of the Bently Nevada 3300 XL family, designed to work seamlessly with compatible proximity probe systems. The 8mm probe with approval option ensures it meets specific regulatory requirements. While this housing assembly does not include a standoff adapter, you can order one separately if your installation requires additional standoff distance. For integration with existing monitoring systems, consult the Bently Nevada documentation to confirm compatibility with your current setup.

Troubleshooting and Common Issues

If you encounter erratic readings, first verify the probe cable connection and ensure the cable length is not stretched or damaged. Check the probe penetration—if it is not set to 0.7 in, the gap may be incorrect. Also, inspect the O-rings for leaks that could allow moisture into the housing. In case of signal loss, confirm that the 3/4-14 NPT plug is properly sealed. For persistent issues, refer to the Bently Nevada troubleshooting guide or contact Petro Auto Tech for technical assistance.
