The Bently Nevada 21504-32-56-10-02 is a precision-engineered 5mm and 8mm standard mount proximity probe designed for non-contact vibration and position monitoring in industrial rotating machinery. As part of the 7200 series transducer system, this probe provides reliable gap-to-voltage measurements, capturing both static and dynamic displacement between the probe tip and the target surface.

Features

• Non-contacting measurement technology for reduced mechanical wear.
• Frequency response range from 0 Hz (DC) to 10 kHz.
• Compatible with standard 7200 series Proximitor systems.
• Designed for high-accuracy shaft position and vibration analysis.
• Includes a 1.0-meter integral coaxial cable with a miniature male connector.

Applications

• Turbines: Monitoring shaft vibration and thrust position in steam and gas turbines.
• Compressors: Tracking axial and radial shaft movement in centrifugal and process gas compressors.
• Pumps & Centrifuges: Detecting displacement to prevent bearing and mechanical seal failure.
• Motors & Generators: Monitoring rotor position and shaft imbalance.

Installation Guidelines

• System Compatibility: Ensure the probe, extension cable, and Proximitor are all from the same series (7200 Series) to maintain system calibration.
• Electrical Length: The total length of the probe cable plus the extension cable must match the calibrated length of the Proximitor (typically 5 or 9 meters).
• Target Material: Standard probes are factory-calibrated for AISI 4140 steel. Using different target materials will alter the scale factor (nominal 200 mV/mil).
• Mounting: Ensure the probe is securely mounted to prevent mechanical resonance. Avoid over-tightening the locknuts to prevent damage to the probe threads.
• Handling: Proximity probes are sensitive electronic components. Handle with care to avoid damaging the probe tip or kinking the coaxial cable.

FAQ

What is the 21504-32-56-10-02 used for?

It is a proximity probe used in 7200 series transducer systems to measure radial vibration, axial position, and speed on rotating machinery by converting gap distance into a proportional voltage signal.

Is this probe compatible with newer systems?

The 7200 series is a legacy system. While it remains in use, many facilities are transitioning to 3300 XL or 3500 series monitoring systems. Always verify your existing system architecture before installation.

Does this probe come with calibration data?

No, this item is supplied as a hardware component. Calibration data, manuals, and additional accessories are not included unless explicitly stated.
