FAQ

1. How does the 330106-05-30-02-CN differ from a standard forward-mount probe?
   The reverse mount version installs from the rear of the mounting structure, reducing exposure to oil or debris and improving probe protection in high-vibration environments.

2. What sensing principle does this probe use?
   It uses the eddy current principle, detecting changes in the electromagnetic field between the probe tip and a conductive target to determine displacement or vibration.

3. Can the probe be connected to any Bently Nevada Proximitor sensor?
   Yes. It is fully compatible with 3300 XL Proximitor sensors and extension cables designed for 8 mm probes.

4. What is the effect of temperature variation on the probe signal?
   The probe is temperature-compensated, maintaining accuracy within ±5% across its full operational temperature range.

5. Is the 330106-05-30-02-CN suitable for use in high-vibration applications?
   Yes. It withstands continuous vibrations up to 20 g and short-term shocks up to 500 g, making it ideal for high-speed rotating equipment.

6. How is electrical noise minimized in this system?
   The probe features an internally shielded coaxial cable that minimizes electromagnetic interference and ground loop effects.

7. What kind of materials can the probe measure?
   It is calibrated for conductive materials, typically AISI 4140 steel, and can measure displacements relative to any ferromagnetic target.

8. Can this probe be used in hazardous areas?
   When used with certified Proximitor sensors, the system can meet ATEX or CSA requirements for hazardous industrial environments.

9. What is the recommended probe gap for optimal measurement?
   The nominal probe-to-target gap is approximately 1.0 mm, adjusted during installation for optimal signal output.

10. How does cable length affect system calibration?
    Each probe and cable assembly is factory-calibrated as a matched system; using non-matching cable lengths can affect sensitivity and linearity.
