Bently Nevada 21504-00-56-05-02 8mm Proximity Transducer System

Complete Model Structure for 21504-00-56-05-02

• The base model 21504 represents the 7200 Series Proximity Transducer platform from Bently Nevada.
• Suffix "00" indicates an unthreaded length of 0 mm, meaning threads run completely to the probe tip for specific mounting applications.
• Suffix "56" specifies an overall case length of 5.6 inches, ensuring proper fit within your machinery's mounting requirements.
• Suffix "05" designates a cable length of 0.5 meters (20 inches) for flexible routing to the proximitor module.
• Suffix "02" confirms the inclusion of a miniature male coaxial connector for secure and reliable signal transmission.

Key Technical Specifications and Performance Data

• Measurement Range: This 21504-00-56-05-02 system provides a full linear output range of 80 mils (2.0 mm) for comprehensive vibration analysis.
• Initial Gap Setting: The linear measurement starts precisely at 10 mils (0.25 mm) from the probe tip to the target surface.
• Output Sensitivity: It delivers a precise signal output of 200 mV/mil (7.87 V/mm) with system calibration accuracy of ±4%.
• System Linearity: The 21504-00-56-05-02 maintains linearity within 0.8 mils, with a maximum interchange error of ±2.3 mils when swapping probes.
• Frequency Response: This transducer monitors dynamic motion from 0 to 10 kHz, with signal attenuation limited to -5% at maximum frequency.
