FAQ

Q1: What is the probe’s frequency response range?

A1: The 3300 XL 8 mm Proximity Probe operates effectively from 0 Hz up to 25 kHz, supporting high-speed shaft monitoring.

Q2: Can this probe be used in explosive environments?

A2: Yes, when paired with an intrinsically safe barrier and proper certification, it can be used in hazardous locations.

Q3: What is the minimum radial clearance for accurate measurement?

A3: For optimal performance, the probe should be installed with a radial clearance of 0.05–0.25 mm from the shaft.

Q4: Does the probe support dual-channel vibration measurement?

A4: It is compatible with dual-channel 3300 XL systems, allowing simultaneous position and vibration monitoring.

Q5: What is the recommended mounting orientation?

A5: The probe can be mounted in any orientation; however, alignment with the monitored shaft centerline is critical.

Q6: How does cable length affect signal accuracy?

A6: Standard 1 m cables maintain signal integrity; longer cables may require signal conditioning to prevent attenuation.

Q7: Can the probe withstand shaft misalignment?

A7: Minor misalignments are tolerated, but large deviations can reduce measurement accuracy and increase wear.

Q8: Is the probe compatible with non-ferrous shafts?

A8: Yes, it functions with both ferrous and non-ferrous shafts, though calibration may differ slightly.

Q9: What type of output does the probe provide?

A9: The probe provides a variable inductive AC output proportional to the gap between the probe tip and shaft.

Q10: How does temperature affect probe readings?

A10: The probe is rated for -40°C to 120°C, and readings remain accurate across this range with minor temperature compensation.
