Industry Applications
The 3300 XL 8mm probe provides high-resolution displacement measurements, enabling early detection of bearing wear, imbalance, or misalignment. By integrating this assembly into a Bently Nevada monitoring system, operators can reduce unplanned outages and extend machinery life.

Installation & Setup Guidance
Mount the housing securely to the machine casing using the 3/4-14 NPT port. Ensure the probe tip is positioned per the manufacturer's gap setting guidelines for the 3300 XL series. The 1.0 m cable allows flexible routing to a junction box or monitor. Use the included thread seal on the NPT plug to maintain environmental integrity. Do not overtighten the dome cover or probe sleeve to avoid thread damage.
Maintenance & Reliability
The 303 stainless steel body and 304 stainless steel sleeve resist corrosion in humid or chemically aggressive atmospheres. Inspect the O-rings and thread seal annually for degradation. Verify cable integrity and connector tightness during routine shutdowns. Replace the assembly if probe tip wear or cable damage is detected. No internal adjustments are required.
Robust Vibration Monitoring for Critical Machinery
In rotating machinery, undetected shaft vibration can lead to catastrophic failure and unplanned downtime. The Bently Nevada 24701-28-10-00-140-04-01 proximity probe housing assembly provides a rugged, sealed enclosure for precise vibration measurement in harsh industrial environments. This assembly integrates a 3300 XL 8mm probe with a 1.0 m cable and a 14-inch probe penetration, ensuring reliable data collection for predictive maintenance programs.

Compatibility & Integration
This assembly is designed for Bently Nevada 3300 XL series proximity probes and compatible monitors (e.g., 3500, 3300 racks). The 14-inch probe penetration suits machines with thick casings or insulation. Verify the mounting thread option (as cast without threads) matches your installation point; if threads are needed, order the appropriate variant.
Selection Guide & Purchasing Advice
When selecting a proximity probe housing, match the probe length, cable length, and penetration to your machine geometry.
