Frequently Asked Questions (FAQ)

Q1: What is the primary function of this probe?

A1: It measures the distance between the probe tip and a rotating shaft to monitor vibration or position changes in real time.

Q2: What does the “0.5 meter” cable length mean?

A2: It is the total length of the permanently attached coaxial cable from the probe tip to the angled connector.

Q3: Can this probe be submerged in oil or coolant?

A3: Yes, with its IP68 rating and stainless-steel construction, it is built to withstand immersion in lubricants and fluids.

Q4: What sensor should I use with this probe?

A4: It is designed to be used with Bently Nevada 3300 XL Proximitor® sensors for optimal performance.

Q5: Is the probe suitable for high-temperature environments?

A5: Yes, it is rated to operate in environments ranging from -35°C up to +177°C.

Q6: How do I verify correct installation depth?

A6: Use a calibrated mechanical spacer tool or a dial indicator to ensure the specified probe-to-target gap.

Q7: Will the probe work if mounted near a magnetic field?

A7: Magnetic fields should be avoided, as they can interfere with eddy current measurements.

Q8: What is the benefit of the 90-degree connector?

A8: It simplifies installation in confined spaces and provides strain relief for cable routing.

Q9: Does the probe require recalibration?

A9: No, once installed with compatible hardware, the system is factory calibrated and does not need field calibration.
