Industry Applications for the 21505-00-28-10-02
Its 200 mV/mil scale factor provides high-resolution data for early fault detection. The stainless steel armor protects the cable in harsh industrial environments, while the 8 mm tip fits standard mounting configurations. By integrating this sensor into your condition monitoring program, you reduce unplanned downtime and extend equipment life.
Installation & Setup Guidance
Mount the 21505-00-28-10-02 using the 3/8-24 thread into a suitable probe holder. Ensure the probe face is clean and the target surface is smooth. Connect the miniature male coaxial connector to the extension cable or proximitor. Power the system with -17.5 Vdc to -26 Vdc at up to 12 mA. Verify the gap voltage at the calibrated range start (approximately 10 mils from probe face) to confirm proper installation.
Maintenance & Reliability
Inspect the probe and cable periodically for physical damage. The stainless steel armor resists corrosion from air, water, lube oil, and several chemicals (ammonium hydroxide, 10% sulfuric acid, MEK, DMF). Keep the probe face free of debris. The system operates reliably from -30°F to +350°F for the probe and cable, making it suitable for demanding environments.
Reliable Vibration Monitoring with the Bently Nevada 21505-00-28-10-02
For maintenance engineers, accurate vibration measurement is critical to protecting rotating machinery. The Bently Nevada 21505-00-28-10-02 is an 8 mm proximity probe designed for the 7200 Proximity Transducer System. This sensor delivers precise, non-contact displacement readings, helping you detect shaft vibration and position changes before they lead to costly failures.
Selection Guide & Purchasing Advice
When selecting a replacement or spare probe, verify the total length and connector type. The 21505-00-28-10-02 includes a 1.0 metre cable with a miniature male coaxial connector. AutoDCSTech stocks this Bently Nevada probe in new, factory-sealed packaging with a 12-month warranty. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
