Product Overview
When unexpected machine downtime threatens production schedules, the Bently Nevada 173688-01-20-12-05 3300 XL 8 mm Proximity Probes provide the precise vibration and position measurements needed for predictive maintenance. Part of the trusted 3300 XL series, this probe is designed for reliability in harsh industrial environments.
Technical Specifications Breakdown
The 173688-01-20-12-05 features a mounting thread of 1/2-14 NPT, ensuring secure installation in standard mounting holes. The unthreaded length option is 0.1 inches, and the overall case length is 2.0 inches. The system length is 2.0 meters (6.6 feet), providing ample reach for most machinery. The connector and cable option is a miniature ClickLoc coaxial connector with FluidLoc cable. The probe tip material is polyphenylene sulfide (PPS), and the probe case material is AISI 303 or 304 stainless steel (SST). The agency approval option includes CSA, ATEX, and IECEx approvals. The weight is 0.323 kg.
Industry Applications
These proximity probes are ideal for monitoring rotating machinery such as turbines, compressors, pumps, and motors. In a typical installation, the 173688-01-20-12-05 mounts directly into the machine casing to measure shaft vibration and axial position. The stainless steel case and PPS tip resist corrosion and wear, making them suitable for both oil and gas and power generation applications.
Installation & Setup Guidance
Mount the probe using a 1/2-14 NPT threaded hole. Ensure the probe tip is clean and free of debris before installation. The FluidLoc cable option is not necessary on most 330105 and 330106 installations due to the probe sleeve; consider your application carefully before ordering this option. Connect the miniature ClickLoc coaxial connector to the extension cable, then route the FluidLoc cable to the monitor. Verify the system length of 2.0 meters matches your setup.
Maintenance & Reliability
For maintenance engineers, the 173688-01-20-12-05 offers long-term reliability. The Viton O-ring seals the differential pressure between the probe tip and case, but probes are not pressure tested before shipment. Contact SpareTechPLC if you require a pressure seal test. Regularly inspect the cable and connector for damage. The stainless steel case and PPS tip require minimal maintenance, reducing overall service costs.
Compatible Systems
This probe integrates with Bently Nevada 3300 XL monitoring systems and other compatible vibration monitoring equipment. The miniature ClickLoc coaxial connector ensures a secure signal connection. Verify compatibility with your existing system before ordering.
Selection Guide & Purchasing Advice
Before purchasing the 173688-01-20-12-05, confirm your required system length and mounting thread. The 0.1-inch unthreaded length and 2.0-inch case length are fixed options. For applications requiring CSA, ATEX, or IECEx approvals, this probe meets those standards. SpareTechPLC is a reliable supplier for this Bently Nevada part.
