Precision Vibration Monitoring with the Bently Nevada 21500-00-12-10-02
Industrial rotating machinery demands reliable, accurate vibration monitoring to prevent catastrophic failures. The Bently Nevada 21500-00-12-10-02 proximity probe is engineered to deliver consistent performance in harsh environments. This 5 mm diameter probe, part of the 7200 Proximitor system, provides non-contact measurement of shaft vibration and position, enabling early detection of issues like imbalance, misalignment, and bearing wear.
Technical Specifications Breakdown
Key parameters for the 21500-00-12-10-02 are listed below for quick reference:

Critical Applications in Rotating Machinery
Its 200 mV/mil scale factor and 0 to 10 kHz frequency response capture both low-speed run-up and high-speed vibration events.
Installation and Setup Guidance
Mount the probe using the 1/4-28 threaded case into a standard mounting hole. Ensure the probe face is within the calibrated range of 10 to 80 mils from the target surface. Use the miniature male coaxial connector for a secure, low-noise connection to the extension cable. Verify total length tolerance of +.25 metre, -.10 metre to avoid cable strain.
Maintenance and Reliability
The probe's stainless steel construction resists corrosion from air, water, lube oil, ammonium hydroxide, sulfuric acid (10%), MEK, or DMF, as specified for 8 mm probes. Inspect the cable and connector periodically for damage. Operating temperature limits of -30°F to +350°F for the probe ensure reliable performance in extreme environments.
Compatibility and Integration
This probe is designed for use with Bently Nevada 7200 series Proximitor systems. The 200 mV/mil output is directly compatible with standard vibration monitors and data collectors. For optimal accuracy, calibrate the probe as a system with its Proximitor and cable.
Selection Guide and Purchasing Advice
When selecting a replacement or spare probe, verify the unthreaded length (0 mm), overall case length (1.2 in), and connector option (miniature male coaxial).
