Technical Specifications Breakdown
The 330903-00-05-50-01-05 provides a linear range of 1.5 mm (60 mils), starting at approximately 0.25 mm from the target. This allows accurate measurement of shaft vibration and axial position within the recommended gap setting of 1.0 mm. The incremental scale factor of 7.87 V/mm ensures consistent output, with interchangeability error accounted for. Deviation from best fit straight line is less than ±0.06 mm, ensuring high measurement accuracy.
The probe operates over a frequency range of 0 to 10 kHz with a typical rolloff of -3 dB, suitable for most rotating machinery monitoring. It can handle field wiring up to 305 meters, making it versatile for various plant layouts.
Industry Applications
-
Process Compressors: The increased chemical resistance of the 330903-00-05-50-01-05 makes it ideal for harsh environments where corrosive media are present.
-
Turbomachinery: Reliable vibration and position monitoring for turbines, compressors, and pumps, ensuring operational safety and efficiency.
-
General Rotating Equipment: Suitable for motors, fans, and gearboxes where shaft proximity measurement is needed for condition monitoring.
Installation & Setup Guidance
Mount the 330903-00-05-50-01-05 with the M8X1 thread, applying finger-tight torque initially, then tighten to a maximum of 0.56 N·m (5 in·lb). Ensure the probe tip is positioned within the recommended gap setting of 1.0 mm (40 mils) from the target surface. For optimal performance, use a three-conductor shielded triad cable with a maximum length of 305 meters between the Proximitor Sensor and the monitor. Follow the frequency response graphs for signal rolloff considerations when using longer field wiring.
Maintenance & Reliability
Regularly inspect the probe cable for damage, especially at bend points, and maintain the minimum bend radius of 25.4 mm to prevent signal degradation. The probe is designed to seal differential pressure with a Viton O-ring; verify the seal integrity during routine maintenance. Operating within the specified temperature range ensures long-term reliability.
Compatibility & Integration
The 330903-00-05-50-01-05 is mechanically and electrically compatible with Bently Nevada's previous 3300 RAM probe and extension cable, allowing seamless upgrades. It works with 3300 XL NSv Proximitor Sensors and compatible monitoring systems. The miniature coaxial ClickLoc connector provides a secure and reliable connection.
Buying Guide
When selecting the 330903-00-05-50-01-05, verify the total probe length (5.0 m) and connector type match your system requirements. Ensure the thread type (M8X1) is compatible with your installation.
