FAQ
Q1: Can the probe measure both radial and axial displacement?
A1: The probe is designed primarily for radial displacement monitoring. Axial measurements require special mounting configurations and additional system considerations.
Q2: What is the signal output type for the 330905 probe?
A2: The probe outputs an AC voltage proportional to shaft displacement, compatible with 3300 NSv monitoring modules.
Q3: Is the 330905 probe compatible with all 3300 series monitors?
A3: Yes, it is compatible with all Bently Nevada 3300 series proximity monitoring systems.
Q4: Can the probe operate at temperatures above 121°C?
A4: The standard model operates up to 121°C. For higher temperatures, a high-temperature variant is required.
Q5: How long can the signal cable be extended beyond 7 meters?
A5: Extensions can affect signal quality. It is recommended to consult Bently Nevada for approved extension cables.
Q6: Does the probe require recalibration after installation?
A6: Factory calibration is sufficient for typical installation, but field verification is recommended to ensure system accuracy.
Q7: Can this probe handle high-speed machinery vibration?
A7: Yes, it is designed for high-speed rotating equipment, providing high-resolution signals up to several kHz.
Q8: What is the expected electrical output range?
A8: The AC voltage output typically varies from 0–10 V peak-to-peak depending on shaft displacement.
Q9: Is the probe shielded against electromagnetic interference?
A9: Yes, the probe cable is shielded to minimize EMI and maintain signal integrity.
Q10: Can the probe be used in explosive or hazardous environments?
A10: Standard probes are not rated for hazardous environments; explosion-proof or intrinsically safe variants are required.
