FAQ

Q1: How does the probe measure shaft vibration?

A1: It uses eddy-current sensing technology to detect changes in the distance between the probe tip and the target shaft surface.

Q2: What is the output signal type?

A2: The probe produces an AC voltage signal proportional to the distance, compatible with 3300 XL monitoring modules.

Q3: Can it be used in high-speed turbines?

A3: Yes, the 8 mm measurement range and high-frequency response make it suitable for high-speed machinery.

Q4: What is the required excitation voltage?

A4: It is designed for use with standard 3300 XL proximity monitoring modules, which provide the correct excitation voltage.

Q5: How is the probe electrically connected?

A5: Through a coaxial cable with BNC or specified connector compatible with 3300 XL systems.

Q6: Is it suitable for wet or humid environments?

A6: Yes, the stainless steel housing and sealed design allow operation in moist conditions.

Q7: Can the probe detect axial as well as radial vibration?

A7: It primarily measures radial shaft displacement; axial vibration monitoring requires multiple probes or specialized configuration.

Q8: How fast can the probe respond to vibration changes?

A8: The probe has a high-frequency response capable of detecting vibrations up to several kHz, suitable for most rotating machinery.

Q9: Does the probe require calibration?

A9: Factory calibration ensures accuracy, but in-field verification may be performed for critical applications.
