24701-16-10-00-090-03-02 | Bently Nevada 8mm Proximity Probe Housing

Introduction to the Bently Nevada 24701-16-10-00-090-03-02

When a rotating machine begins to vibrate unexpectedly, the 24701-16-10-00-090-03-02 from Bently Nevada provides the precise mounting solution needed for accurate proximity probe readings. This housing assembly is engineered to protect the probe and maintain consistent gap measurements in demanding industrial environments.

As part of the 24701 series, this model is built with a 303 stainless steel body and a 304 stainless steel sleeve, ensuring durability and corrosion resistance. The assembly includes a dome cover, threaded ports for conduit connections, a probe sleeve, O-rings, a reverse mount proximity probe, and a thread seal, along with optional conduit fittings and standoff adapter.

Key Features and Technical Specifications

• Probe Option: 16 = 3300 XL 8mm probe with connector
• Probe Cable Length: 10 = 39 in (1.0 m)
• Standoff Adapter: None (00)
• Probe Penetration: 090 = 9 in
• Fittings Option: 03 – includes one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer, and one cable seal grip with grommets for cable sizes 1/8 to 3/16, 1/4 to 5/16, and 5/16 to 3/8 inches
• Mounting Thread: 02 = 3/4-14 NPT (required when standoff adapter option is not -00)
• Material: 303 stainless steel body, 304 stainless steel sleeve
• Weight: 1.8 kg (4.1 lb) typical, without fittings

The maximum (C) + (D) dimension with visible probe (P/N and S/N) is 17.0 in (43.18 mm), and the overall maximum is 29.2 in (74.2 mm). These dimensions ensure proper probe positioning for accurate measurements.

Real-World Application and Performance

In a typical scenario, a plant engineer notices increased vibration on a critical pump. The 24701-16-10-00-090-03-02 housing assembly allows them to mount the 3300 XL 8mm probe securely, providing reliable data for condition monitoring. The 9-inch penetration depth suits installations where the probe must reach through thick machine casings.

Because the housing is made of stainless steel, it withstands harsh process environments without degrading. The included fittings simplify conduit connections, reducing installation time. With a 1.0 m cable, the probe connects easily to nearby monitoring equipment.

Installation and Setup Guidance

When installing the 24701-16-10-00-090-03-02, ensure the mounting thread (3/4-14 NPT) is properly sealed to prevent leakage. Use the provided cable seal grip with the appropriate grommet for your cable diameter. Verify that the probe penetration depth matches your machine's requirements—this model offers 9 inches.

For best results, follow the manufacturer's recommended torque values for the dome cover and fittings. Always check that the probe tip is positioned correctly relative to the target surface, as the gap affects the measurement accuracy.

Maintenance and Reliability

Regular inspection of the housing assembly helps maintain reliable performance. Periodically check the O-rings and thread seal for wear, and ensure the dome cover remains tight. Clean the exterior with a soft cloth to remove dirt and debris, but avoid using solvents that could damage the seals.

Because the housing is constructed from corrosion-resistant stainless steel, it offers long service life even in humid or chemical-laden atmospheres. This durability reduces replacement frequency, contributing to lower maintenance costs over time.

Compatibility and Integration

The 24701-16-10-00-090-03-02 is designed for use with Bently Nevada 3300 XL 8mm proximity probes. It integrates seamlessly with Bently Nevada monitoring systems, providing accurate vibration and position signals. The 1.0 m cable length is suitable for many machine train configurations.

For installations requiring a standoff adapter, note that this model does not include one (option 00). If your application needs a standoff, please contact Petro Auto Tech for guidance on the correct variant.
