製品紹介
The Bently Nevada 330102-00-28-10-02-00 is a complete 8mm proximity transducer system from the 3300 XL series. It serves as the primary sensor for measuring vibration and axial position on critical rotating machinery like turbines, compressors, and pumps. The system works on the eddy current principle to provide accurate, non-contact monitoring, converting physical shaft motion into a precise DC voltage signal for the 3300 XL monitor to interpret.

FAQ
1. Why is the target material specification critical?
The electrical calibration is specific to steel. Non-standard materials (e.g., stainless, aluminum) will produce inaccurate readings.
2. Can a damaged extension cable be repaired?
番号 Any repair changes the cable’s capacitance, distorting the signal. The entire cable must be replaced.
3. What does the negative output voltage indicate?
It is a system convention. A voltage near -2V indicates a small gap, near -18V a large gap, and -24V indicates an open circuit fault.
4. What is electrical runout?
An error signal caused by variations in the shaft material’s magnetic properties, which can be misinterpreted as vibration.
5. How is the system calibrated?
The scale factor is set in the monitor. Field verification is done by measuring the output voltage at a known physical gap.
6. What does a “Probe Gap” fault mean?
This indicates an open circuit or short circuit in the probe system, requiring electrical troubleshooting / the loop.
7. What is the difference between standard and reverse-drive probes?
Standard probes (this model) have electronics in the connector. Reverse-drive models have electronics in the tip for higher temperature applications.
8. Why is the frequency response important?
A 10 kHz range ensures the system can accurately capture high-frequency vibration events common in machinery.
9. Can this probe measure casing vibration?
番号 It measures relative shaft displacement. For absolute casing vibration, an accelerometer is required.
10. What is the purpose / the termination resistor?
It prevents signal reflection on the cable. An incorrect value will distort the measurement signal.
