Bently Nevada 21504-00-48-10-00 Proximity Probe Vibration Sensor

Technical Specifications Breakdown

Key parameters for the 21504-00-48-10-00 are listed below for quick reference:

Industry Applications and Failure Prevention

The 80 mil (2.0 mm) calibrated range and 200 mV/mil scale factor provide high-resolution data for early detection of shaft rub, imbalance, or misalignment. By catching these faults early, maintenance teams can avoid catastrophic failures and unplanned downtime. The probe's corrosion resistance to common industrial fluids like lube oil and water makes it suitable for refinery and power generation environments.

Installation and Setup Guidance

Proper installation is critical for accurate readings. The 21504-00-48-10-00 features a 3/8-24 thread and an unthreaded length of 0 mm, meaning the entire case length (4.8 in) is threaded. Ensure the probe face is clean and the target surface is smooth. The calibrated range begins at approximately 10 mils (0.25 mm) from the probe face. Use the supplied 1.0 metre cable (without connector) to connect to the proximitor. Avoid sharp bends in the cable and secure it away from high-voltage lines.

Maintenance and Reliability

The probe is designed for long-term reliability with no moving parts. Periodically inspect the cable for abrasion or chemical attack. The system operates reliably in relative humidity up to 95% noncondensing. For 8 mm probes, operation is not affected by direct contact with air, water, lube oil, ammonium hydroxide, 10% sulfuric acid, MEK, or DMF. No field calibration is required if the system was factory-calibrated; however, verify the scale factor periodically per plant procedures.

Selecting the Right Vibration Sensor for Rotating Machinery

When monitoring critical rotating assets, the choice of proximity probe directly impacts measurement accuracy and machine reliability. The Bently Nevada 21504-00-48-10-00 is an 8 mm proximity probe from the trusted 7200 series, engineered for continuous vibration and position monitoring in harsh industrial environments. This guide helps you evaluate whether this sensor meets your application requirements.

Compatibility and Integration

This probe is part of the Bently Nevada 7200 proximity transducer system. It is designed to work with compatible proximitors and extension cables. The -00 connector option indicates no connector is included, so you must select the appropriate mating connector for your system. The frequency response of 0 to 10 kHz covers most machinery vibration monitoring needs, including high-speed turbines.

Selection Guide and Purchasing Advice

When selecting the 21504-00-48-10-00, confirm your required total length (1.0 m in this variant) and connector type.
