FAQ
Q1: What is the operating principle of the 3300 XL 25 mm probe?
A1: It uses the eddy current principle, generating a signal proportional to the distance between the probe tip and the conductive shaft surface.
Q2: Can this probe detect both static and dynamic shaft movements?
A2: Yes, it measures static shaft position (displacement) and dynamic vibration simultaneously.
Q3: How does the probe maintain accuracy in high-temperature environments?
A3: The design incorporates temperature-compensated electronics and robust materials to ensure stable output.
Q4: What type of cable is used with this probe?
A4: It uses a durable coaxial cable with integrated shielding to minimize signal interference.
Q5: Is this probe interchangeable with other 3300 XL series probes?
A5: Yes, but calibration and driver compatibility must be confirmed to ensure system accuracy.
Q6: What is the frequency response capability of this probe?
A6: It supports frequency response up to 10 kHz, making it suitable for most machinery vibration monitoring.
Q7: Can it be used for thrust position monitoring?
A7: Yes, the probe is designed for both radial vibration and axial (thrust) position measurements.
Q8: How is the probe calibrated?
A8: Calibration is performed using Bently Nevada Proximitor drivers to match probe characteristics.
Q9: Does the probe support long cable extensions?
A9: Yes, but only with specific matched cable lengths as per Bently Nevada’s specifications to maintain accuracy.
Q10: What is the typical installation distance (gap) from the shaft surface?
A10: The probe is typically installed with a nominal gap of 2 mm, but exact values depend on shaft material and driver settings.
