21505-00-40-10-02 is a Bently Nevada 7200 Series 8mm non-contact proximity probe featuring rugged stainless steel armor and an integrated miniature male coaxial connector. Fully compatible with 7200 Proximitors and extension cables, this unit works seamlessly with 3300 and 9000 Monitoring Systems to deliver stable non-contact shaft displacement and radial vibration data.
Technical Data Summary
System Type: Noncontacting gap-to-voltage transducer for static and dynamic distance measurements.
Frequency Response: 0 Hz (DC) to 10 kHz, capturing both position and vibration data.
Linear Range: Offers 80 mils (2 mm) of linear measuring range for accurate displacement readings.
Compatibility: Fully compatible with 3300 and 9000 Monitoring Systems and meets API 670 requirements.
Applications: Designed for shaft position and vibration monitoring on turbines, compressors, pumps, and motors.
Configuration: Includes a probe with a 1.0-meter integral coaxial cable and miniature male coaxial connector.
Application
Radial Vibration Monitoring: Continuously tracks shaft movement to indicate oil-film fluid bearing conditions and detect early machine malfunctions such as rotor imbalance and misalignment.
Axial Thrust Position Tracking: Measures dynamic axial displacement to determine thrust bearing wear or potential bearing assembly failure on rotating components.
Mid-Sized Machine Machinery Enclosures: Ideal for intermediate casing depths where the physical mounting wall or bracket thickness requires a medium-length 4.0-inch thread engagement.
