製品紹介
The Bently Nevada 330906-02-12-10-12-RU 3300 NSv Reverse Mount Probe is a precision-engineered, non-contact eddy-current sensor specifically designed for reverse mounting in critical rotating machinery. This model enables installation in restricted or unconventional locations where standard probe orientation is not feasible. As part / the 3300 NSv (Narrow Side-view) series, it provides highly reliable shaft vibration and displacement measurements, ensuring early detection / mechanical issues such as rotor imbalance, misalignment, and bearing wear. Built to withstand harsh industrial environments, this probe features robust stainless-steel construction and integrated electromagnetic interference (EMI) protection, making it a critical component for predictive maintenance and machinery protection programs.

FAQ
-
How is the 330906-02-12-10-12-RU probe calibrated for accurate displacement measurement?
Each 台 is factory-calibrated using an AISI 4140 steel target to ensure linearity and sensitivity. -
Can this reverse mount probe work with standard Bently Nevada Proximitor drivers?
Yes, it integrates seamlessly with the 3300 XL Proximitor and approved NSv extension cables. -
What is the maximum measurable vibration frequency for this probe?
It accurately measures vibration signals up to 10 kHz within its linear range. -
What type / output signal does the probe provide?
The output is a voltage proportional to shaft displacement, typically 0–20 V peak-to-peak. -
Is additional electromagnetic shielding required in high-noise areas?
番号 Integrated EMI shielding ensures reliable performance without external shielding. -
Can the probe be installed in pressurized or oil-submerged environments?
Yes, it is rated up to 500 psi and suitable for submerged or pressurized applications. -
How is measurement accuracy maintained across wide temperature variations?
