FAQ

Q1: What type of signal does the 3300 XL 11 mm probe output?

The probe outputs an AC or DC voltage signal proportional to the displacement of the shaft.

Q2: Can this probe be used on high-speed turbines?

Yes, it is rated for shaft speeds up to 60,000 RPM.

Q3: What is the maximum operating temperature?

The probe operates reliably from -40°C to +120°C.

Q4: Is this probe compatible with non-Bently monitoring systems?

Yes, it can be used with any system that accepts AC/DC voltage displacement signals, provided the input specifications match.

Q5: How should the probe be mounted for accurate readings?

The probe can be mounted using a stud or clamp mount. Proper alignment with the shaft is critical for precise measurements.

Q6: Does the cable require special shielding?

Yes, the cable is a shielded twisted pair, designed to minimize electromagnetic interference.

Q7: Can the probe detect axial as well as radial vibrations?

It is primarily designed for radial vibration and displacement measurement.

Q8: What maintenance is required for this probe?

Routine inspection for cable damage and connector integrity is recommended. No calibration is typically required under normal conditions.

Q9: How long can the cable be extended without affecting performance?

Cable extensions should generally not exceed the manufacturer’s recommended limits (consult Bently Nevada guidelines) to avoid signal attenuation.

Q10: Can the probe be used in explosive or hazardous environments?

The standard probe is not intrinsically safe; for hazardous locations, an approved certified version is required.
