FAQ

Q1: How does the 330103-00-08-05-12-05 proximity probe measure shaft vibration?

A1: It uses an eddy current principle to sense changes in the electromagnetic field caused by shaft motion, converting them into voltage signals proportional to displacement.

Q2: What signal output does this probe generate?

A2: The probe produces a linear output of approximately 200 mV per mil (7.87 mV/µm) of shaft displacement.

Q3: Can this probe be used with extension cables of different lengths?

A3: Yes, but it must be matched with the correct Proximitor sensor to maintain calibration and accuracy.

Q4: How is the probe gap adjusted during installation?

A4: The probe should be set to its nominal gap (typically 1.0 mm) using a non-conductive feeler gauge to ensure accurate baseline measurements.

Q5: Is the probe resistant to electromagnetic interference (EMI)?

A5: Yes, the 3300 XL series incorporates shielding to reduce the effects of EMI in industrial environments.

Q6: What type of shaft materials provide optimal performance with this probe?

A6: The probe is calibrated for 4140 steel (with a conductivity factor of 1.0). Performance may vary slightly with other alloys.

Q7: How does the probe interface with a monitoring system?

A7: It connects via an extension cable to a 3300 XL Proximitor sensor, which conditions the signal for monitoring and protection systems.

Q8: Can the probe be used in hazardous environments?

A8: Yes, with proper installation and certification, the probe can be used in ATEX or Class I Division 2 hazardous environments.

Q9: What happens if the probe is mounted too close or too far from the shaft?

A9: Incorrect gap settings can cause non-linear output, reduced sensitivity, or inaccurate displacement readings.

Q10: Does the probe support dynamic vibration and static position measurements?

A10: Yes, it is designed to provide both static shaft position and dynamic vibration monitoring simultaneously.
