The 330180-51-CN is an industrial eddy current proximity probe designed for high-precision monitoring of shaft vibration and displacement in rotating machinery. It is widely used in condition monitoring systems that require continuous, non-contact measurement of machine dynamics to ensure operational safety and reliability.
This probe is typically installed in turbines, compressors, pumps, and other critical rotating equipment where real-time vibration and position data are essential for predictive maintenance. It forms part of a complete measurement system that includes extension cables and signal conditioning modules.
The “CN” suffix generally indicates a regional configuration variant optimized for specific installation standards, packaging requirements, or environmental compliance conditions.
