Frequently Asked Questions (FAQ)

1. How does the PR6424/118-100 detect shaft movement?

   It uses the eddy current principle, sensing changes in the electromagnetic field caused by a conductive target moving near the sensor head.

2. What type of output does the sensor provide?

   It outputs a voltage proportional to displacement, which can be conditioned by a compatible converter.

3. What is the sensor’s frequency range?

   The sensor operates from DC up to 10 kHz, suitable for static and dynamic monitoring.

4. Can it measure both radial and axial movements?

   It is designed primarily for radial displacement measurement. Axial changes may influence readings slightly.

5. How is accuracy maintained in noisy environments?

   Shielded coaxial cable and proper grounding, along with the stainless steel housing, minimize interference.

6. Is it suitable for predictive maintenance?

   Yes, it can monitor vibration trends and detect early signs of unbalance or misalignment.

7. How does it interface with monitoring systems?

   Through a CON021 or CON041 converter, which provides power and conditions the output for integration.

8. What target materials can it detect?

   It measures conductive materials like steel or metal alloys. Non-conductive targets cannot be measured.

9. Can it provide real-time data for protection systems?
