Industry Applications for the 24701-28-10-00-110-04-01
The 3300 XL 8mm probe provides accurate displacement measurements. Typical applications include:
- Steam Turbines: The 11-inch probe penetration allows installation through bearing housings. The stainless steel construction resists oil and moisture.
- Centrifugal Compressors: The sealed housing protects the probe from process gas leaks. The 1.0 m cable length suits compact installations.
- Large Pumps: The assembly withstands high vibration levels. The NPT plug fitting simplifies conduit connections.

Installation & Setup Guidance
Mount the housing assembly securely to the machine case using the as-cast mounting thread option. Ensure the probe tip is properly positioned per the manufacturer's gap setting guidelines. Use the provided O-rings and thread seal to maintain environmental integrity. The 3/4-14 NPT plug fitting should be tightened to prevent leakage. Verify cable routing to avoid sharp bends or abrasion.
Maintenance & Reliability
Periodically inspect the dome cover and conduit fittings for signs of corrosion or loosening. The 303/304 stainless steel materials offer good resistance to industrial atmospheres. Check the O-rings during routine machine outages and replace if hardened or cracked. No internal adjustments are required.
Robust Vibration Monitoring with the Bently Nevada 24701-28-10-00-110-04-01
Industrial rotating machinery demands precise and reliable vibration monitoring to prevent catastrophic failures. The Bently Nevada 24701-28-10-00-110-04-01 Proximity Probe Housing Assembly provides a complete, sealed solution for mounting a proximity probe in harsh environments. This assembly integrates a 3300 XL 8mm probe with a 1.0 m cable, an 11-inch probe penetration, and a 303 stainless steel body with a 304 stainless steel sleeve. It is designed for continuous operation in critical applications such as steam turbines, compressors, and pumps.

Compatibility & Integration
The assembly accepts a 3300 XL 8mm proximity probe with a connector. It is compatible with Bently Nevada monitor systems that accept 8mm probe inputs. The 1.0 m cable length may require extension cables for distant monitor racks.
