FAQ
Q1: What is the maximum operating frequency for this probe?
A1: The probe operates effectively up to 10 kHz, ensuring accurate response for most rotating machinery applications.
Q2: Can this probe be used in high-temperature environments above 120°C?
A2: Standard operation is rated to 121°C; for higher temperatures, specialized high-temperature probes should be considered.
Q3: What type of signal does the 3300 XL probe output?
A3: The probe generates an AC voltage signal proportional to the target’s displacement.
Q4: Is the probe shielded against electromagnetic interference (EMI)?
A4: Yes, it uses a coaxial shielded cable to minimize EMI and maintain signal integrity.
Q5: Can this probe measure axial and radial shaft movement?
A5: It is primarily designed for radial displacement; axial measurements require a specific setup or additional probes.
Q6: What is the recommended mounting distance from the target shaft?
A6: The standard gap is 0.25–1.0 mm for optimal linearity and signal strength.
Q7: Can the cable length be extended beyond 1 meter?
A7: Yes, extensions are possible, but signal integrity must be verified for longer lengths.
Q8: How resistant is the probe to vibration and shock?
A8: It is rated to withstand up to 100 g vibrations and transient mechanical shocks.
Q9: Does the probe require calibration before installation?
A9: Each probe is factory-calibrated; however, verification is recommended during initial system setup.
Q10: Can this probe be used with non-Bently monitoring systems?
A10: It may function with other systems, but optimal performance and signal interpretation are guaranteed only with the 3300 XL system.
