• Standoff Adapter: 2.0 inches, allowing correct probe positioning relative to the target surface.
• Probe Penetration: 2.4 inches, defining how far the probe extends into the housing.
• Mounting Thread: 3/4-14 NPT, a common industrial standard for secure installation.
• Fittings Option: 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 various cable sizes.
• Material: 303 stainless steel body with a 304 stainless steel sleeve, offering corrosion resistance and durability.
• Weight: 1.8 kg (4.1 lb) typical without fittings, making it manageable for installation.

These specifications combine to deliver a housing that protects the probe and maintains signal integrity. The stainless steel construction ensures longevity even in harsh industrial settings.

Applications and Use Cases

The 24701-28-05-20-024-03-02 is well-suited for vibration monitoring on rotating equipment such as turbines, compressors, and pumps. In these applications, accurate proximity measurement is critical for detecting shaft vibration and axial position. By using this housing assembly, you can mount the probe securely and consistently, reducing measurement variability.

For example, in a steam turbine installation, the housing protects the probe from environmental contaminants while maintaining the correct gap. This reliability helps in early detection of mechanical issues, potentially avoiding costly downtime. Additionally, the housing's design allows for easy access during maintenance, simplifying routine checks.

Installation and Setup

Proper installation is essential for optimal performance of the 24701-28-05-20-024-03-02. Begin by verifying that the mounting thread (3/4-14 NPT) matches your installation point. The standoff adapter (2.0 inches) should be used to position the probe correctly relative to the target surface, ensuring the probe penetration (2.4 inches) is achieved.

When connecting the probe cable (0.5 m), ensure that the cable seal grip is used with the appropriate grommet for your cable diameter. The fittings option includes grommets for cable sizes from 1/8 to 3/8 inches, providing flexibility. Tighten all connections securely to prevent loosening due to vibration. It is also important to follow the manufacturer's guidelines for probe gap setting to achieve accurate readings.

Maintenance and Reliability

Regular maintenance of the 24701-28-05-20-024-03-02 ensures long-term reliability. Periodically inspect the housing for signs of wear or damage, especially the O-rings and thread seal. These components help maintain the integrity of the enclosure, protecting the probe from moisture and debris.

Because the housing is made of stainless steel, it resists corrosion, but it is still wise to check for any buildup of contaminants that could affect performance. If the probe cable or connector shows signs of damage, replace them promptly to avoid signal loss. Following a routine inspection schedule, as recommended by Bently Nevada, will help extend the service life of the assembly.

Compatibility and Integration

The 24701-28-05-20-024-03-02 is designed to work with 3300 XL 8mm proximity probes, which are widely used in Bently Nevada monitoring systems. This housing assembly integrates seamlessly with these probes, ensuring that you can maintain a consistent monitoring setup. The mounting thread option (3/4-14 NPT) is a standard industrial connection, making it compatible with many existing installations.

For systems that require a different mounting configuration, the standoff adapter can be adjusted, but note that the mounting thread option must be selected when the standoff adapter length is not -00. This flexibility allows the housing to be adapted to various machine geometries, enhancing its versatility.
