FAQ

Q1: How does the 330102-00-48-05-02-05 probe detect shaft vibration?

A1: It uses eddy current principles to measure the distance between the probe tip and the conductive shaft surface, converting this displacement into an electrical signal.

Q2: What is the linear measurement range of this probe?

A2: The probe offers a linear range of 2.0 mm (80 mils).

Q3: Can this probe operate in high-temperature environments?

A3: Yes, it supports operating temperatures up to +177 °C, suitable for most industrial rotating equipment.

Q4: Is the probe compatible with older Bently Nevada monitoring systems?

A4: It is optimized for the 3300 XL Proximitor sensors, but also backward compatible with certain earlier systems when matched correctly.

Q5: How is the probe signal transmitted to the monitoring system?

A5: The probe connects to an extension cable, which links to the Proximitor sensor. The conditioned signal is then transmitted to monitoring equipment.

Q6: What type of shielding is used to prevent interference?

A6: The probe incorporates advanced electromagnetic shielding and grounded stainless steel construction.

Q7: Can the probe be used for both vibration and position measurements?

A7: Yes, it can measure both dynamic vibration and static shaft position (relative displacement).

Q8: What is the sensitivity of this probe?

A8: The sensitivity is 200 mV/mil (±6.5%).

Q9: Does cable length affect calibration accuracy?

A9: Yes, probes are calibrated with specific extension cable lengths. Using mismatched lengths may affect linearity and accuracy.
