FAQ

1. Q: What is the recommended gap setting for the 8 mm probe?

   A: The typical operating gap is 0.127–2.54 mm (0.005–0.100 in) for optimal signal accuracy.

2. Q: Can this probe handle high-speed machinery vibrations above 20 kHz?

   A: Yes, the probe supports frequency response up to 25 kHz.

3. Q: What type of cable is compatible with this probe?

   A: The probe uses a shielded 2-wire cable designed for 3300 XL systems.

4. Q: Is the probe suitable for explosive atmospheres?

   A: This standard model is not intrinsically safe; an optional certified model is required for hazardous environments.

5. Q: How does the probe interface with the 3300 XL monitor?

   A: The probe provides differential output that connects directly to the 3300 XL module input.

6. Q: Can the probe detect axial as well as radial vibrations?

   A: The probe primarily measures radial shaft vibration; axial vibration requires additional configuration or monitoring probes.

7. Q: How is the probe calibrated?

   A: Calibration is performed using standard shunt calibration or reference gap methods in the 3300 XL system.

8. Q: Can the probe operate in high humidity or wet environments?

   A: Yes, the stainless steel housing and sealed design protect against moisture and condensation.

9. Q: Is there any signal drift over time?

   A: Properly installed 3300 XL probes show minimal signal drift; periodic validation is recommended.

10. Q: What is the maximum cable length without signal degradation?

    A: Standard configuration supports up to 11 meters; longer distances may require signal conditioning.
