FAQ

Q1: How does the 330903-00-04-05-02-RU achieve non-contact measurement?

A1: It uses an eddy-current principle, generating a magnetic field at the probe tip which interacts with the conductive shaft surface to measure displacement.

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

A2: It typically supports 0.25 mm to 2.0 mm of linear range for accurate vibration detection.

Q3: Is this probe optimized for small-diameter shafts?

A3: Yes, the NSv design specifically enhances sensitivity for smaller shafts where traditional probes may not provide reliable measurements.

Q4: Can it be used in high-temperature environments?

A4: It operates effectively from -35 °C to +180 °C, making it suitable for most industrial temperature ranges.

Q5: What Proximitor driver is required for proper operation?

A5: It must be used with the 3300 NSv Proximitor sensor, which is calibrated specifically for this probe series.

Q6: How does the probe handle electromagnetic interference?

A6: The cable and probe assembly are shielded to minimize the effects of EMI and ensure stable output signals.

Q7: What is the typical output sensitivity of this probe?

A7: It delivers around 200 mV/mil (7.87 V/mm), which matches standard Bently Nevada system requirements.

Q8: Can this probe be installed in oil-lubricated machine housings?

A8: Yes, it is designed with robust sealing and insulation, allowing installation in lubricated or contaminated environments.
