Technical Specifications Breakdown

Key parameters for the 24701-28-05-00-070-00-02 are listed below for quick reference:

Industry Applications: Solving Real-World Vibration Monitoring Challenges

Consider a gas turbine in a power plant where bearing housing vibration must be measured with high repeatability. The 24701-28-05-00-070-00-02 housing assembly secures the 3300 XL 8mm probe at a precise 0.7-inch penetration depth, preventing probe retraction due to thermal expansion or mechanical shock. The 303 stainless steel body resists corrosion from lubricating oil and moisture, while the 304 stainless steel sleeve protects the probe cable from abrasion.

Installation & Setup Guidance

Before installation, verify that the mounting surface is clean and free of debris. The 3/4-14 NPT thread (Mounting Thread Option 02) allows direct threading into standard conduit ports or standoff adapters. Ensure the probe cable length of 0.5 m is sufficient to reach the monitoring system without excessive bending. The probe penetration of 0.7 in must be set precisely to achieve the recommended gap voltage for the 3300 XL system. Use the included O-rings and thread seal to prevent leakage of process fluids into the housing. Do not overtighten the dome cover—hand-tighten plus one-quarter turn is typically sufficient.

Maintenance & Reliability

Periodically inspect the housing assembly for signs of corrosion, especially in outdoor or washdown areas. Check the O-rings for cracking or compression set every 12 months. Verify that the probe cable is not pinched or chafed at the entry point. The 303/304 stainless steel construction provides resistance to most industrial environments, but avoid exposure to chlorides above 50 ppm to prevent pitting. If the assembly is removed for maintenance, replace the thread seal and O-rings to ensure a proper seal.

Robust Protection for Critical Vibration Monitoring

In industrial rotating machinery, accurate vibration measurement depends on a stable, well-protected proximity probe installation. The Bently Nevada 24701-28-05-00-070-00-02 Proximity Probe Housing Assembly provides a rugged, sealed enclosure for the 3300 XL 8mm probe, ensuring reliable data collection in harsh environments. This assembly eliminates common failure points such as probe movement, contamination, and cable strain, making it a trusted choice for turbine, compressor, and pump monitoring systems.

Compatibility & Integration

The 24701-28-05-00-070-00-02 is designed for use with Bently Nevada 3300 XL 8mm proximity probes and compatible monitors (e.g., 3500, 3300 series). The assembly includes a reverse mount proximity probe and a probe sleeve of optional length. The optional standoff adapter (not included in this suffix code) can be ordered separately if additional standoff length is needed. The 3/4-14 NPT mounting thread is a common industrial standard, simplifying integration into existing conduit systems.

Selection Guide & Purchasing Advice

When ordering the 24701-28-05-00-070-00-02, confirm that the probe cable length (0.5 m) and penetration depth (0.7 in) match your application requirements. If you need a different cable length or penetration, select the appropriate suffix codes. The assembly is supplied without fittings (Fittings Option 00); order conduit fittings separately if required. AutoDCSTech offers this assembly as new and original in factory packing, backed by a 12-month warranty. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
