FAQ

Q1: What is the optimal probe gap for accurate measurement?

A1: The optimal gap for the 8 mm probe tip is 0.13 mm to 0.25 mm (5–10 mils) depending on the shaft material and rotation speed.

Q2: Can this probe be used with non-ferrous shafts?

A2: Yes, the probe operates on eddy current principles and can detect both ferrous and non-ferrous materials.

Q3: What is the maximum cable length without signal degradation?

A3: The 3300 XL system supports cable lengths up to 30 meters while maintaining signal fidelity.

Q4: Is this probe compatible with all 3300 XL monitors?

A4: Yes, it is fully compatible with standard 3300 XL monitors that accept 8 mm probes.

Q5: How does temperature affect the probe performance?

A5: The probe operates reliably within -40°C to +125°C. Temperature variations within this range have negligible impact on measurement accuracy.

Q6: Can the probe detect shaft vibration at high RPMs?

A6: Yes, it supports a frequency response up to 25 kHz, suitable for high-speed machinery applications.

Q7: Is the probe resistant to electromagnetic interference (EMI)?

A7: Yes, the coaxial cable design and grounding method provide excellent EMI resistance.

Q8: How does the probe output signal behave under shaft misalignment?
