Bently Nevada 21504-08-32-10-02 8 mm Proximity Probe, 80 mm Unthreaded Length

Technical Specifications Breakdown

Key parameters for the 21504-08-32-10-02 are listed below for quick reference:

Industry Applications and Failure Prevention

In steam turbines, the 8 mm probe detects shaft vibration within a calibrated range of 80 mils (2.0 mm), enabling early detection of imbalance or misalignment. For centrifugal compressors, the 200 mV/mil scale factor provides high-resolution data for trend analysis, reducing unplanned downtime. The probe's corrosion resistance to air, water, lube oil, and common chemicals ensures reliable operation in refinery and chemical plant environments.

Installation and Setup Guidance

Proper installation is critical for accurate readings. Mount the probe with the 3/8-24 thread configuration, ensuring the tip is positioned within the calibrated range (begins at approximately 10 mils from the probe face). The total length of 1.0 metre (39 inches) with a miniature male coaxial connector simplifies wiring to the proximitor. Maintain a clean, non-conductive gap between the probe face and the target surface to avoid false signals.

Maintenance and Reliability

Routine inspection of the probe and cable is recommended, especially in high-temperature or corrosive environments. The probe operates reliably from -30°F to +350°F (-34°C to +177°C), but verify that the proximitor remains within its -60°F to +212°F range. Check the connector for corrosion or damage periodically. The system weight of 1.3 lbs (0.59 kg) is minimal, reducing mechanical stress on mounting brackets.

Reliable Vibration Monitoring with the Bently Nevada 21504-08-32-10-02

Industrial rotating machinery demands precise, continuous vibration monitoring to prevent catastrophic failures. The Bently Nevada 21504-08-32-10-02 is an 8 mm proximity probe designed for the 7200 series, delivering accurate displacement measurements in harsh environments. This component is essential for protecting turbines, compressors, and pumps by detecting shaft vibration and position changes early.

Compatibility and Integration

The 21504-08-32-10-02 is part of the Bently Nevada 7200 Proximity Transducer Systems family. The 8 mm probe diameter and 3/8-24 thread are standard for many industrial applications, allowing straightforward replacement of existing probes.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the unthreaded length (80 mm), overall case length (3.2 in), and total length (1.0 m) match your installation requirements. The connector option (miniature male coaxial) ensures compatibility with your system. AutoDCSTech stocks this Bently Nevada probe as new and original in factory packing with a 12-month warranty.
