FAQ
Q1: How does the 330103-00-08-50-12-00 proximity probe measure displacement?
A1: It operates on eddy current principles, generating a voltage proportional to the distance between the probe tip and the conductive shaft surface.
Q2: What is the optimal installation gap for this probe?
A2: The recommended nominal gap is 2.0 mm, which ensures linear operation within the specified measurement range.
Q3: Can this probe be used with extension cables of different lengths?
A3: Yes, it supports extension cables, but they must match Bently Nevada’s 3300 XL specifications to maintain system calibration.
Q4: How does temperature affect measurement accuracy?
A4: The probe is temperature compensated within its operating range, ensuring minimal variation in sensitivity even at high temperatures.
Q5: Is the probe immune to electromagnetic interference?
A5: The coaxial cable design and shielding provide strong resistance to EMI, making it suitable for electrically noisy environments.
Q6: What Proximitor sensor is compatible with this probe?
A6: It is designed to work with the Bently Nevada 3300 XL Proximitor Sensor (model 3300 5 mm/8 mm systems).
Q7: How should the probe be mounted for optimal performance?
A7: It should be threaded securely into a rigid mount, perpendicular to the shaft surface, ensuring stable and repeatable measurements.
Q8: What is the maximum shaft speed this probe can monitor?
A8: While there is no fixed speed limit, it reliably monitors vibration frequencies up to 10 kHz, suitable for high-speed machinery.
Q9: How does cable length affect signal accuracy?
A9: Only specified probe, extension cable, and proximitor combinations ensure calibrated performance; mismatched lengths may cause scale factor errors.
Q10: Can this probe be used in hazardous area installations?
A10: Yes, when paired with certified proximitor sensors and installed according to Bently Nevada’s guidelines for hazardous locations.
