FAQ

Q1: What type of signal output does the probe provide?

A1: The probe provides a voltage output proportional to the distance between the probe tip and the shaft surface, typically 200 mV/mil (7.87 V/mm).

Q2: Can the probe be used with standard 3300 XL Proximitor sensors?

A2: No, it is specifically designed for use with 3300 NSv Proximitor sensors due to its smaller linear range.

Q3: What is the typical linear measurement range of this probe?

A3: The linear range is 0.25 mm to 2.0 mm, optimized for small clearance applications.

Q4: How does cable length affect performance?

A4: The probe is calibrated as part of a matched system with its extension cable and proximitor. Using incorrect cable lengths can result in inaccurate readings.

Q5: Does the probe support both dynamic and static measurements?

A5: Yes, it measures both dynamic shaft vibration (AC) and static shaft position (DC).

Q6: What surface finish is required on the shaft for accurate readings?

A6: A smooth, conductive surface with a recommended finish of 0.8 µm Ra or better is required.

Q7: What is the maximum frequency response of the probe?

A7: The probe can reliably measure signals up to 10 kHz.

Q8: Is the probe affected by temperature variations?

A8: It is temperature-compensated but extreme temperature changes can slightly influence sensitivity.

Q9: Can the probe be used in hazardous (ATEX/IECEx) environments?

A9: Yes, when paired with appropriately certified proximitor systems, it complies with hazardous area requirements.

Q10: How is the probe grounded to minimize electrical noise?

A10: The probe uses a coaxial shield design and should be properly grounded through the proximitor to reduce interference.
