FAQ
-
How does the 330105-02-12-05-02-RU probe measure shaft displacement?
It uses the eddy current principle, producing a voltage signal proportional to the distance between the probe tip and the conductive shaft surface. -
What shaft materials are compatible with this probe?
Conductive metals, primarily steel, are recommended for accurate displacement and vibration measurement. -
What is the probe’s frequency response range?
The probe operates from DC to 20 kHz, allowing detection of both slow shaft movements and high-frequency vibrations. -
Can it monitor both radial and axial shaft movement?
Yes, depending on orientation, it can capture either radial vibration or axial displacement. -
How is linearity ensured throughout the measuring range?
The combination of probe design and 3300 XL system linearization maintains measurement within ±1% of full-scale. -
Can this probe integrate with other Bently Nevada systems?
It is optimized for 3300 XL systems but can interface with systems that accept standard voltage outputs. -
How does the probe handle electromagnetic interference?
Shielded cabling and robust electronics reduce the impact of EMI and RFI, ensuring stable output signals. -
Is it suitable for high-temperature industrial environments?
