FAQ

Q1: What is the maximum cable length supported without signal loss?

A1: Standard cable length is 5 m, but extensions up to 30 m can be used with appropriate signal conditioning.

Q2: Can this probe operate in high humidity environments?

A2: Yes, the probe housing is sealed and suitable for humid or wet industrial conditions.

Q3: What type of output does the probe provide?

A3: The probe provides eddy-current AC signal compatible with 3300 XL monitor inputs.

Q4: Is it compatible with non-ferromagnetic targets?

A4: No, eddy-current probes require ferromagnetic target materials for proper operation.

Q5: What is the frequency range of the sensor?

A5: The sensor supports up to 50 kHz, making it suitable for high-speed machinery.

Q6: How is the probe calibrated?

A6: Calibration is performed using standard Bently Nevada calibration fixtures or via the monitor’s built-in calibration routine.

Q7: Can this probe detect both radial and axial vibration?

A7: It primarily measures radial shaft displacement; axial measurements require appropriate sensor orientation.

Q8: What mounting options are available?

A8: Threaded mounting and push-fit installation are supported for flexible integration.

Q9: How resistant is the probe to electrical noise?

A9: The probe is designed with shielding to minimize electromagnetic interference in industrial environments.
