Bently Nevada 330103-00-08-10-12-RU 3300 XL 8 mm Proximity Probe

FAQ

• Q: What is the required target material for this probe to achieve specified performance?

  • A: The probe is calibrated for use with 4140 steel or material with equivalent electromagnetic properties.

• Q: What is the maximum extension cable length that can be used with this probe?

  • A: The total system cable length (probe + extension) should not exceed 305 meters (1000 feet) to ensure signal integrity.

• Q: Can this probe be used to measure the vibration of brass or aluminum shafts?

  • A: No, it is not recommended. The probe is calibrated for steel. Measurements on non-ferrous materials like brass or aluminum will be inaccurate due to different material conductivity and permeability.

• Q: What is the purpose of the RU suffix in the model number?

  • A: The “RU” typically indicates regional or special certification, often for the Russian market or Customs Union (EAC certification).

• Q: How is the probe’s output voltage interpreted?

  • A: The DC voltage represents the average gap (position) between the probe tip and the target. The AC voltage superimposed on the DC signal represents dynamic motion (vibration).

• Q: What is the recommended installation gap (air gap) for this probe?

  • A: The optimal initial gap is typically between 0.76 mm and 1.27 mm (30 mils and 50 mils) from the target, within its linear range, to allow for both positive and negative vibration.

• Q: Is this probe intrinsically safe for use in hazardous environments?

  • A: The probe itself is a passive sensor. Intrinsic safety is achieved by connecting it to a compatible intrinsically safe certified monitor/system that provides appropriate energy-limiting barriers.

• Q: Can the probe cable be spliced or repaired if damaged?

  • A: It is strongly discouraged. Any splice or repair can significantly alter cable capacitance and electrical characteristics, degrading system performance and calibration. Replacement of the entire cable assembly is the recommended practice.
