Frequently Asked Questions (FAQ)
1. What does the part number 330101-00-12-05-02-00 indicate?
It refers to a Bently Nevada 3300 XL 8mm probe with a 12-foot cable, 1/4-28 UNF thread, straight connector, and standard configuration without armor.
2. Can this probe be used with all Proximitor sensors?
It is designed to be used specifically with the 3300 XL Proximitor Sensor for optimal performance and accuracy.
3. Is this probe suitable for high-temperature environments?
Yes. It supports operation up to 177°C (350°F), making it ideal for turbines and compressors.
4. What material is the probe calibrated to?
It is factory calibrated to AISI 4140 steel, a common shaft material in industrial equipment.
5. Can this be used for thrust position measurement?
Yes. When mounted axially, it effectively monitors shaft position to track thrust bearing wear.
6. Does it require recalibration over time?
Recalibration is not typically needed unless environmental conditions significantly change or the installation is disturbed.
7. How is the cable terminated?
The probe uses a ClickLoc™ coaxial connector which ensures a secure and tool-free connection to the extension cable.
8. What is the recommended gap between the probe and shaft?
The nominal gap is 1.0 mm (40 mils), adjustable during installation to suit target material and desired output.
9. How do I identify cable length from the part number?
The third and fourth digits (00-12) refer to the 12-foot length of the probe cable.
10. What is the typical output signal of this probe?
It provides a voltage output of approximately -200 mV/mil (≈ -7.87 mV/μm), linear over its full range.
