FAQ

Q1: How does the probe maintain accuracy in high-temperature environments?

A1: The probe is constructed with temperature-stable materials and calibration that compensates for expansion effects, ensuring consistent sensitivity up to +177 °C.

Q2: Can the probe be used with extension cables longer than 9 m?

A2: The probe is calibrated for specific cable lengths. Using longer cables may affect signal integrity and is not recommended without factory re-calibration.

Q3: What is the typical signal output when measuring shaft displacement?

A3: The probe outputs a voltage signal proportional to shaft displacement, typically -200 mV per mil of displacement.

Q4: Is the probe immune to oil film interference in journal bearings?

A4: Yes, the probe is designed to penetrate oil films and maintain accurate measurement of shaft-to-probe distance.

Q5: How does the probe perform in electrically noisy environments?

A5: The coaxial cable design and shielding provide strong noise immunity, maintaining accuracy in environments with high EMI.

Q6: Can the probe be installed in both axial and radial configurations?

A6: Yes, it can be mounted to measure shaft vibration radially or thrust position axially, depending on monitoring requirements.

Q7: What happens if the probe is not calibrated with the correct cable length?

A7: Mismatch in probe, extension cable, and proximitor length can cause errors in sensitivity and linearity. Correct matching is essential.

Q8: Does the probe require periodic recalibration?

A8: Factory calibration is highly stable. Recalibration is typically only needed after cable replacement or system modification.

Q9: How does the probe respond to very high-frequency vibrations?

A9: It maintains effective response up to 10 kHz, suitable for most rotating machinery monitoring applications.

Q10: Can this probe detect shaft rub or misalignment events?

A10: Yes, the probe can capture sudden displacement spikes or changes in vibration patterns that indicate rubs, misalignment, or rotor instability.
