FAQ
1. What is the recommended linear range of this probe?
The probe offers a typical linear range of up to 2 mm when used with the correct Proximitor sensor.
2. Does the 5 m cable length affect calibration?
No, as long as the probe, extension cable, and Proximitor are ordered and matched as a system, calibration is preserved.
3. Can the probe be used for both radial and axial measurements?
Yes, it can be installed for either radial shaft vibration monitoring or axial thrust position measurement.
4. How does the probe interface with the monitoring system?
It connects to an extension cable and Proximitor sensor, which converts displacement into a proportional voltage signal for monitoring modules.
5. What is the signal output characteristic?
It provides a voltage signal linearly proportional to the distance between the probe tip and the shaft surface.
6. Can the probe be used in hazardous or classified environments?
Yes, with proper installation and certified Proximitor systems, it is suitable for hazardous industrial zones.
7. What impact does probe tip size have on measurement?
The 8 mm probe tip is optimized for balance between measurement range and installation space, making it suitable for a wide range of machinery.
8. Does this probe require grounding or shielding?
Yes, proper grounding and shielding are required to minimize electrical noise and ensure accurate measurements.
9. How does temperature variation influence probe accuracy?
The probe is designed with thermal stability features, ensuring minimal drift across its –35 °C to +180 °C operating range.
10. Is the probe backward compatible with legacy Bently Nevada systems?
Yes, it is compatible with most existing 3300 and 3500 series monitoring systems, supporting legacy installations.
