FAQ

Q1: What is the operating principle of this proximity probe?

A1: It works on the eddy current principle, generating a high-frequency magnetic field that induces eddy currents in the conductive shaft surface. The probe detects changes in current flow proportional to the shaft distance.

Q2: Can this probe measure both radial and axial displacement?

A2: Yes, the probe can be mounted either radially to monitor shaft vibration or axially to monitor thrust position.

Q3: What is the maximum gap voltage output of the probe?

A3: The probe provides a DC voltage proportional to shaft displacement, typically up to -24 VDC at maximum gap.

Q4: How is linearity maintained across the measurement range?

A4: The probe, extension cable, and Proximitor® sensor are matched as a calibrated system, ensuring linear response across the 2 mm range.

Q5: What is the effect of target material on measurement accuracy?

A5: The probe is factory-calibrated for 4140 steel; use with other materials requires correction factors to maintain accuracy.

Q6: Is the probe shielded against electromagnetic interference?

A6: Yes, the probe incorporates coaxial shielding to minimize EMI, ensuring reliable performance in noisy environments.

Q7: What frequency response does the system support?

A7: The probe supports DC to 10 kHz frequency response, suitable for monitoring high-speed rotating machinery.

Q8: Can the probe operate in hazardous areas?

A8: Certain variants are available with hazardous area certifications (ATEX, CSA, IECEx). Users should verify the marking on the device.

Q9: What is the recommended installation torque for the mounting thread?

A9: Typically, 2.8 to 3.4 N·m is recommended, ensuring secure mounting without damaging the probe.

Q10: Does cable length affect probe calibration?

A10: Yes, the system is calibrated for specific cable lengths (e.g., 5 m, 9 m). Using incorrect cable lengths without recalibration will reduce accuracy.
