FAQ

Q1: How does the 3300 XL 8 mm probe achieve accurate displacement measurement?

A1: It uses eddy-current technology that generates a stable magnetic field, detecting changes in distance between the probe tip and the shaft surface.

Q2: Can this probe be directly connected to the monitoring system without a proximitor?

A2: No, it must be connected to a 3300 XL Proximitor Sensor, which conditions the signal before transmission to the monitoring system.

Q3: What is the typical sensitivity calibration of this probe?

A3: The probe provides a sensitivity of approximately 200 mV/mil (7.87 mV/µm), ensuring precise measurement of shaft displacement.

Q4: Is the probe affected by shaft surface conditions?

A4: Yes, shaft material and surface finish can influence accuracy; standard practice recommends using a conductive, polished surface.

Q5: How is electrical noise minimized in this probe?

A5: The cable and probe feature superior shielding to suppress EMI and RFI, ensuring clean signals even in noisy industrial environments.

Q6: What happens if the system length does not match probe specifications?

A6: Mismatched system lengths can result in incorrect calibration and inaccurate measurements; probes must be paired with the correct extension cable and proximitor.

Q7: How does temperature variation impact probe performance?

A7: The probe is designed with thermal stability, maintaining accuracy across -35 °C to +177 °C, though extreme fluctuations may still introduce minor drift.

Q8: Can the probe be used in hazardous environments?

A8: Yes, when installed with properly rated proximitor and extension cables, it can comply with hazardous area certifications.

Q9: How is probe linearity tested?

A9: Linearity is verified during calibration using reference targets, ensuring consistent response throughout the measurement range.

Q10: What is the maximum cable length supported in this configuration?

A10: The system supports a total length of 5 m, comprising the probe cable and extension cable, without affecting accuracy.
