FAQ

Q1: What is the primary function of the 330903 NSv probe?

A1: Its main function is to measure shaft vibration and displacement in rotating machinery for monitoring and protection.

Q2: Can this probe operate with standard 3300 XL systems?

A2: The probe is designed specifically for the NSv system and should be used with its dedicated NSv Proximitor sensor, not directly with standard XL systems.

Q3: What is the sensitivity rating of this probe?

A3: It has a sensitivity of 7.87 mV/µm (200 mV/mil).

Q4: How does it differ from the standard 3300 XL probe?

A4: The NSv version is optimized for applications with narrow gaps and limited clearance, unlike the standard XL probes.

Q5: Is the probe suitable for axial position monitoring?

A5: Yes, it is widely used for thrust position monitoring in turbines and compressors.

Q6: What is the frequency response range of this probe?

A6: It supports DC to 10 kHz frequency response.

Q7: Does the probe require calibration after installation?

A7: Factory calibration ensures accuracy, but system verification and loop checks are recommended after installation.

Q8: Can it withstand high-temperature environments?

A8: Yes, it is rated to operate from -35 °C up to +177 °C.

Q9: What type of signal does the probe generate?

A9: It generates a voltage signal proportional to shaft displacement, which is processed by the Proximitor sensor.

Q10: Is it API 670 compliant?

A10: Yes, it fully meets the API 670 standards for machinery protection.
