FAQ

Q1: How does the 330903-00-03-50-02-RU probe measure shaft vibration?
A1: It uses eddy current technology, generating an electromagnetic field and detecting changes in the conductive shaft surface to measure displacement and vibration.

Q2: What signal does the probe provide to the monitoring system?
A2: It outputs a voltage proportional to the shaft-to-probe distance, typically -200 mV/μm.

Q3: Can this probe be used with standard 3300 Proximitor sensors?
A3: No, it is specifically designed for the 3300 NSv Proximitor sensors to ensure proper calibration and linearity.

Q4: What is the typical linear range of the probe?
A4: The linear range is 0.25 mm to 2.0 mm (10 to 80 mils).

Q5: How does temperature affect measurement accuracy?
A5: The probe is designed with temperature compensation to minimize drift across its full operating range (-35°C to +177°C).

Q6: What is the maximum pressure rating of the probe housing?
A6: It can withstand up to 10,000 psi, making it suitable for high-pressure machinery.

Q7: What type of connector is used on this probe?
A7: It uses a miniature coaxial connector compatible with NSv extension cables.

Q8: Can the probe be installed in hazardous environments?
A8: Yes, with proper certifications and installation guidelines, it is suitable for hazardous and explosive environments.

Q9: Does the probe require recalibration during its service life?
A9: Typically, no recalibration is needed unless there is cable damage or sensor replacement.

Q10: How is electrical interference minimized in this probe?
A10: It features shielded coaxial cable design and grounded stainless steel housing to reduce noise and interference.
