Frequently Asked Questions (FAQ)
-
What sensing principle does this probe use?
It employs eddy-current sensing to measure shaft displacement without physical contact. -
How is signal linearity maintained?
Internal calibration circuits and temperature-compensated materials ensure consistent, linear output. -
Can it be used with Bently Nevada 3300 XL Proximitor® modules?
Yes, it is fully compatible for accurate displacement monitoring. -
How does the probe handle electromagnetic interference?
Shielded housing and proper grounding minimize signal distortion caused by EMI. -
Is it capable of capturing high-frequency vibrations?
Yes, its frequency response up to 10 kHz allows detection of rapid shaft motion. -
What is required for proper mounting?
Install on a rigid, flat surface with correct alignment and recommended probe-to-shaft gap. -
Which shaft types are supported?
Conductive metallic shafts work best; non-conductive coatings can interfere with measurement. -
Does temperature affect accuracy?
Low-expansion materials and built-in compensation minimize errors from temperature changes. -
