FAQ

1. What is the operating principle of the 330103-05-10-10-12-RU probe?

   The probe works on the eddy-current principle, generating a voltage signal proportional to the distance between the probe tip and the conductive shaft surface.

2. Why is the probe tip size fixed at 8mm?

   The 8mm design balances high sensitivity with durability, ensuring accurate readings even in confined spaces and high-speed machinery applications.

3. How does this probe interact with the proximitor?

   The probe detects shaft displacement, the signal is transmitted through the extension cable, and the proximitor conditions it into a voltage output suitable for monitoring systems.

4. What kind of output signal does the probe deliver?

   It provides a linear voltage output of 7.87 mV/µm (200 mV/mil), standardized across the 3300 XL series.

5. Does cable length affect performance?

   Yes, the probe is factory-calibrated with a specific extension cable length. Using mismatched lengths can result in inaccurate readings.

6. Can this probe operate in hazardous areas?

   When paired with approved proximitor systems, the probe can be applied in hazardous environments as part of certified installations.

7. What is the maximum frequency range supported?

   The probe supports a frequency range up to 10 kHz, ensuring reliable monitoring of both slow-speed and high-speed rotating equipment.

8. Is the probe resistant to electromagnetic interference?

   Yes, it is fully shielded to protect against EMI and RFI, which are common in industrial environments.
