Bently Nevada 21504-00-36-10-02 Proximity Probe Vibration Sensor

Technical Specifications Breakdown

Key parameters for the 21504-00-36-10-02 are listed below for quick reference:

Industry Applications: Preventing Costly Failures

The 80 mil (2.0 mm) calibrated range and 200 mV/mil scale factor provide high-resolution data for trend analysis. With a frequency response up to 10 kHz, it captures both low-speed runout and high-frequency vibration events, enabling operators to schedule maintenance before catastrophic failure occurs.

Installation and Setup Guidance

Mount the probe using the 3/8-24 thread into a properly tapped hole, ensuring the probe face is clean and free of debris. The unthreaded length option 00 (0 mm) means the tip extends directly from the case. Connect the miniature male coaxial connector to the extension cable, observing the -17.5 Vdc to -26 Vdc power requirement. Verify the gap voltage at initial installation to confirm the probe is within the linear range (approximately 10 mils from the target surface).

Maintenance and Reliability

The probe and extension cable operate reliably from -30°F to +350°F, making them suitable for high-temperature turbine environments. The 8 mm probe construction resists corrosion from air, water, lube oil, ammonium hydroxide, sulfuric acid (10%), MEK, and DMF. Inspect the probe tip and cable periodically for physical damage or contamination. No special maintenance is required beyond routine visual checks and verifying system calibration annually.

Reliable Vibration Monitoring for Critical Machinery

Unplanned downtime from rotating machinery failures can cost industrial plants thousands per hour. The Bently Nevada 21504-00-36-10-02 proximity probe provides precise, non-contact vibration and position measurements, enabling early detection of shaft instability, misalignment, and bearing wear. This 8 mm diameter probe is engineered for continuous operation in harsh environments, delivering the accuracy needed for predictive maintenance programs.

Compatibility and Integration

This probe is part of the Bently Nevada 7200 Proximity Transducer System. It interfaces directly with compatible proximitor and monitor modules. The miniature male coaxial connector ensures a secure, noise-resistant connection. For best performance, use the probe with Bently Nevada extension cables and proximitors designed for 8 mm probes.

Selection Guide and Purchasing Advice

When selecting a replacement or spare probe, verify the overall case length (3.6 in) and total cable length (1.0 metre) match your installation requirements. The 21504-00-36-10-02 is supplied new in original factory packing with a 12-month warranty from AutoDCSTech. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
