FAQ
-
How is the 330905-07-17-05-02-05 probe calibrated for precise displacement measurement?
Each unit is factory-calibrated using an AISI 4140 steel target to maintain sensitivity and linearity. -
Can this probe interface with different Bently Nevada Proximitor drivers?
Yes, it integrates seamlessly with the 3300 XL Proximitor and approved NSv extension cables. -
What is the maximum vibration frequency range it can detect?
It measures vibration signals up to 10 kHz within the specified linear range. -
What is the typical output signal characteristic of this probe?
The output is a voltage signal proportional to shaft displacement, typically 0–20 V peak-to-peak. -
Is additional electromagnetic shielding required for high-noise environments?
No. Integrated shielding ensures stable performance without external EMI protection. -
Can the probe operate in pressurized or oil-submerged environments?
Yes, it is pressure-rated up to 500 psi and suitable for submerged installations. -
How is measurement accuracy maintained under temperature fluctuations?
Stainless-steel construction and internal compensation preserve accuracy across the operating range. -
Is the probe capable of monitoring both radial and axial displacement?
Yes, orientation during installation determines whether radial or axial vibration is monitored. -
What signal conditioning equipment is required for optimal operation?
A Bently Nevada 3300 XL Proximitor or equivalent driver provides the required power and signal processing. -
Does the extension cable length affect calibration or sensitivity?
Yes. Each probe is calibrated for a specific cable length, so the correct matching extension cable is essential.
