FAQ
Q1: How does the 330901-00-21-05-12-05 probe interface with the monitoring system?
A1: It connects through an extension cable to the 3300 NSv driver, which conditions and transmits the signal to the monitoring system.
Q2: What is the primary output of this probe?
A2: The probe provides a voltage proportional to the distance between the probe tip and the shaft surface.
Q3: Is the probe suitable for high-speed rotating machinery?
A3: Yes, it is optimized for turbomachinery and other high-speed applications requiring precise vibration monitoring.
Q4: Can the probe detect both vibration and position?
A4: Yes, it measures dynamic vibration as well as static shaft position (axial displacement).
Q5: What type of target material does it require for accurate operation?
A5: The probe is designed for conductive targets, typically steel shaft surfaces.
Q6: How does the probe handle electrical noise?
A6: Shielded cabling and proper grounding minimize interference, ensuring signal integrity.
Q7: What happens if the probe-to-target gap exceeds its linear range?
A7: The output becomes nonlinear, reducing measurement accuracy and requiring repositioning.
Q8: Can this probe be used interchangeably with standard 3300 XL probes?
A8: No, the 3300 NSv series is specifically designed for narrow-space applications and requires its matching drivers and cables.
Q9: Does the probe require calibration in the field?
A9: No, the probe is factory-calibrated but should be installed at the recommended gap to ensure accuracy.
Q10: How does the probe behave under extreme temperature variations?
A10: It maintains performance within its specified operating temperature range of -35 °C to +177 °C.
